Introduction

RippleAPI (ripple-lib) is the official client library to the XRP Ledger. Currently, RippleAPI is only available in JavaScript. Using RippleAPI, you can:

• Query transactions from the XRP Ledger history
• Sign transactions securely without connecting to any server
• Submit transactions to the XRP Ledger, including Payments, Orders, Settings changes, and other types
• Generate a new XRP Ledger Address
• ... and much more.

Boilerplate

Use the following boilerplate code to wrap your custom code using RippleAPI.

const RippleAPI = require('ripple-lib').RippleAPI;

const api = new RippleAPI({
  server: 'wss://s1.ripple.com' // Public rippled server hosted by Ripple, Inc.
});
api.on('error', (errorCode, errorMessage) => {
  console.log(errorCode + ': ' + errorMessage);
});
api.on('connected', () => {
  console.log('connected');
});
api.on('disconnected', (code) => {
  // code - [close code](https://developer.mozilla.org/en-US/docs/Web/API/CloseEvent) sent by the server
  // will be 1000 if this was normal closure
  console.log('disconnected, code:', code);
});
api.connect().then(() => {
  /* insert code here */
}).then(() => {
  return api.disconnect();
}).catch(console.error);

RippleAPI is designed to work in Node.js version 6.11.3. RippleAPI may work on older Node.js versions if you use Babel for ECMAScript 6 support.

The code samples in this documentation are written with ECMAScript 6 (ES6) features, but RippleAPI also works with ECMAScript 5 (ES5). Regardless of whether you use ES5 or ES6, the methods that return Promises return ES6-style promises.

All the code snippets in this documentation assume that you have surrounded them with this boilerplate. If you omit the "catch" section, errors may not be visible. The "error" event is emitted whenever an error occurs that cannot be associated with a specific request. If the listener is not registered, an exception will be thrown whenever the event is emitted.

Parameters

The RippleAPI constructor optionally takes one argument, an object with the following options:

Name	Type	Description
authorization	string	Optional Username and password for HTTP basic authentication to the rippled server in the format username:password.
certificate	string	Optional A string containing the certificate key of the client in PEM format. (Can be an array of certificates).
feeCushion	number	Optional Factor to multiply estimated fee by to provide a cushion in case the required fee rises during submission of a transaction. Defaults to 1.2.
key	string	Optional A string containing the private key of the client in PEM format. (Can be an array of keys).
maxFeeXRP	string	Optional Maximum fee to use with transactions, in XRP. Must be a string-encoded number. Defaults to '2'.
passphrase	string	Optional The passphrase for the private key of the client.
proxy	uri string	Optional URI for HTTP/HTTPS proxy to use to connect to the rippled server.
proxyAuthorization	string	Optional Username and password for HTTP basic authentication to the proxy in the format username:password.
server	uri string	Optional URI for rippled websocket port to connect to. Must start with wss:// or ws://.
timeout	integer	Optional Timeout in milliseconds before considering a request to have failed.
trace	boolean	Optional If true, log rippled requests and responses to stdout.
trustedCertificates	array<string>	Optional Array of PEM-formatted SSL certificates to trust when connecting to a proxy. This is useful if you want to use a self-signed certificate on the proxy server. Note: Each element must contain a single certificate; concatenated certificates are not valid.

If you omit the server parameter, RippleAPI operates offline.

Installation

1. Install Node.js and Yarn. Most Linux distros have a package for Node.js; check that it's the version you want.
2. Use yarn to install RippleAPI: yarn add ripple-lib

After you have installed ripple-lib, you can create scripts using the boilerplate and run them using the Node.js executable, typically named node:

  `node script.js`

Offline functionality

RippleAPI can also function without internet connectivity. This can be useful in order to generate secrets and sign transactions from a secure, isolated machine.

To instantiate RippleAPI in offline mode, use the following boilerplate code:

const RippleAPI = require('ripple-lib').RippleAPI;

const api = new RippleAPI();
/* insert code here */

Methods that depend on the state of the XRP Ledger are unavailable in offline mode. To prepare transactions offline, you must specify the fee, sequence, and maxLedgerVersion parameters in the transaction instructions. You can use the following methods while offline:

• preparePayment
• prepareTrustline
• prepareOrder
• prepareOrderCancellation
• prepareSettings
• prepareEscrowCreation
• prepareEscrowCancellation
• prepareEscrowExecution
• sign
• generateAddress
• computeLedgerHash

Basic Types

Address

"r9cZA1mLK5R5Am25ArfXFmqgNwjZgnfk59"

Every XRP Ledger account has an address, which is a base58-encoding of a hash of the account's public key. XRP Ledger addresses always start with the lowercase letter r.

Account Sequence Number

Every XRP Ledger account has a sequence number that is used to keep transactions in order. Every transaction must have a sequence number. A transaction can only be executed if it has the next sequence number in order, of the account sending it. This prevents one transaction from executing twice and transactions executing out of order. The sequence number starts at 1 and increments for each transaction that the account makes.

Currency

Currencies are represented as either 3-character currency codes or 40-character uppercase hexadecimal strings. We recommend using uppercase ISO 4217 Currency Codes only. The string "XRP" is disallowed on trustlines because it is reserved for the XRP Ledger's native currency. The following characters are permitted: all uppercase and lowercase letters, digits, as well as the symbols ?, !, @, #, $, %, ^, &, *, <, >, (, ), {, }, [, ], and |.

Value

A value is a quantity of a currency represented as a decimal string. Be careful: JavaScript's native number format does not have sufficient precision to represent all values. XRP has different precision from other currencies.

XRP has 6 significant digits past the decimal point. In other words, XRP cannot be divided into positive values smaller than 0.000001 (1e-6). This smallest unit is called a "drop". XRP has a maximum value of 100000000000 (1e11). Some RippleAPI methods accept XRP in order to maintain compatibility with older versions of the API. For consistency with the rippled APIs, we recommend formally specifying XRP values in drops in all API requests, and converting them to XRP for display. This is similar to Bitcoin's satoshis and Ethereum's wei. 1 XRP = 1,000,000 drops.

Non-XRP values have 16 decimal digits of precision, with a maximum value of 9999999999999999e80. The smallest positive non-XRP value is 1e-81.

Amount

Example 100.00 USD amount:

{
  "currency": "USD",
  "counterparty": "rMH4UxPrbuMa1spCBR98hLLyNJp4d8p4tM",
  "value": "100"
}

Example 3.0 XRP amount, in drops:

{
  "currency": "drops",
  "value": "3000000"
}

(Requires ripple-lib version 1.0.0 or higher.)

An amount is an object specifying a currency, a quantity of that currency, and the counterparty (issuer) on the trustline that holds the value. For XRP, there is no counterparty.

A lax amount allows the counterparty to be omitted for all currencies. If the counterparty is not specified in an amount within a transaction specification, then any counterparty may be used for that amount.

A lax lax amount allows either or both the counterparty and value to be omitted.

A balance is an amount than can have a negative value.

Name	Type	Description
currency	currency	The three-character code or hexadecimal string used to denote currencies, or "drops" for the smallest unit of XRP.
counterparty	address	Optional The Ripple address of the account that owes or is owed the funds (omitted if currency is "XRP" or "drops")
value	value	Optional The quantity of the currency, denoted as a string to retain floating point precision

Transaction Overview

Transaction Types

A transaction type is specified by the strings in the first column in the table below.

Type	Description
payment	A payment transaction represents a transfer of value from one account to another. Depending on the path taken, additional exchanges of value may occur atomically to facilitate the payment.
order	An order transaction creates a limit order. It defines an intent to exchange currencies, and creates an order in the XRP Ledger's order book if not completely fulfilled when placed. Orders can be partially fulfilled.
orderCancellation	An orderCancellation transaction cancels an order in the XRP Ledger's order book.
trustline	A trustline transactions creates or modifies a trust line between two accounts.
settings	A settings transaction modifies the settings of an account in the XRP Ledger.
escrowCreation	An escrowCreation transaction creates an escrow on the ledger, which locks XRP until a cryptographic condition is met or it expires. It is like an escrow service where the XRP Ledger acts as the escrow agent.
escrowCancellation	An escrowCancellation transaction unlocks the funds in an escrow and sends them back to the creator of the escrow, but it will only work after the escrow expires.
escrowExecution	An escrowExecution transaction unlocks the funds in an escrow and sends them to the destination of the escrow, but it will only work if the cryptographic condition is provided.
checkCreate	A checkCreate transaction creates a check on the ledger, which is a deferred payment that can be cashed by its intended destination.
checkCancel	A checkCancel transaction cancels an unreedemed Check, removing it from the ledger without sending any money.
checkCash	A checkCash transaction redeems a Check to receive up to the amount authorized by the corresponding checkCreate transaction. Only the destination address of a Check can cash it.
paymentChannelCreate	A paymentChannelCreate transaction opens a payment channel between two addresses with XRP set aside for asynchronous payments.
paymentChannelFund	A paymentChannelFund transaction adds XRP to a payment channel and optionally sets a new expiration for the channel.
paymentChannelClaim	A paymentChannelClaim transaction withdraws XRP from a channel and optionally requests to close it.

Transaction Flow

Executing a transaction with RippleAPI requires the following four steps:

1. Prepare - Create an unsigned transaction based on a specification and instructions. There is a method to prepare each type of transaction:
   • preparePayment
   • prepareTrustline
   • prepareOrder
   • prepareOrderCancellation
   • prepareSettings
   • prepareEscrowCreation
   • prepareEscrowCancellation
   • prepareEscrowExecution
   • prepareCheckCreate
   • prepareCheckCancel
   • prepareCheckCash
2. Sign - Cryptographically sign the transaction locally and save the transaction ID. Signing is how the owner of an account authorizes a transaction to take place. For multisignature transactions, the signedTransaction fields returned by sign must be collected and passed to the combine method.
3. Submit - Submit the transaction to the connected server.
4. Verify - Verify that the transaction got validated by querying with getTransaction. This is necessary because transactions may fail even if they were successfully submitted.

Transaction Fees

Every transaction must destroy a small amount of XRP as a cost to send the transaction. This is also called a transaction fee. The transaction cost is designed to increase along with the load on the XRP Ledger, making it very expensive to deliberately or inadvertently overload the peer-to-peer network that powers the XRP Ledger.

You can choose the size of the fee you want to pay or let a default be used. You can get an estimate of the fee required to be included in the next ledger closing with the getFee method.

Transaction Instructions

Transaction instructions indicate how to execute a transaction, complementary with the transaction specification.

Name	Type	Description
fee	value	Optional An exact fee to pay for the transaction. See Transaction Fees for more information.
maxFee	value	Optional Deprecated: Use maxFeeXRP in the RippleAPI constructor instead. The maximum fee to pay for this transaction. If this exceeds maxFeeXRP, maxFeeXRP will be used instead. See Transaction Fees for more information.
maxLedgerVersion	integer,null	Optional The highest ledger version that the transaction can be included in. If this option and maxLedgerVersionOffset are both omitted, the maxLedgerVersion option will default to 3 greater than the current validated ledger version (equivalent to maxLedgerVersionOffset=3). Use null to not set a maximum ledger version.
maxLedgerVersion	string,null	Optional The highest ledger version that the transaction can be included in. If this option and maxLedgerVersionOffset are both omitted, the maxLedgerVersion option will default to 3 greater than the current validated ledger version (equivalent to maxLedgerVersionOffset=3). Use null to not set a maximum ledger version.
maxLedgerVersionOffset	integer	Optional Offset from current validated ledger version to highest ledger version that the transaction can be included in.
sequence	sequence	Optional The initiating account's sequence number for this transaction.
signersCount	integer	Optional Number of signers that will be signing this transaction.

We recommend that you specify a maxLedgerVersion so that you can quickly determine that a failed transaction will never succeeed in the future. It is impossible for a transaction to succeed after the XRP Ledger's consensus-validated ledger version exceeds the transaction's maxLedgerVersion. If you omit maxLedgerVersion, the "prepare*" method automatically supplies a maxLedgerVersion equal to the current ledger plus 3, which it includes in the return value from the "prepare*" method.

Transaction ID

"F4AB442A6D4CBB935D66E1DA7309A5FC71C7143ED4049053EC14E3875B0CF9BF"

A transaction ID is a 64-bit hexadecimal string that uniquely identifies the transaction. The transaction ID is derived from the transaction instruction and specifications, using a strong hash function.

You can look up a transaction by ID using the getTransaction method.

Transaction Memos

Every transaction can optionally have an array of memos for user applications. The memos field in each transaction specification is an array of objects with the following structure:

Name	Type	Description
data	string	Optional Arbitrary string, conventionally containing the content of the memo.
format	string	Optional Conventionally containing information on how the memo is encoded, for example as a MIME type. Only characters allowed in URLs are permitted.
type	string	Optional Conventionally, a unique relation (according to RFC 5988) that defines the format of this memo. Only characters allowed in URLs are permitted.

Transaction Specifications

A transaction specification specifies what a transaction should do. Each Transaction Type has its own type of specification.

Payment

See Transaction Types for a description.

Name	Type	Description
source	object	The source of the funds to be sent.
source. address	address	The address to send from.
source. amount	laxAmount	An exact amount to send. If the counterparty is not specified, amounts with any counterparty may be used. (This field is exclusive with source.maxAmount)
source. tag	integer	Optional An arbitrary unsigned 32-bit integer that identifies a reason for payment or a non-Ripple account.
source. maxAmount	laxAmount	The maximum amount to send. (This field is exclusive with source.amount)
destination	object	The destination of the funds to be sent.
destination. address	address	The address to receive at.
destination. amount	laxAmount	An exact amount to deliver to the recipient. If the counterparty is not specified, amounts with any counterparty may be used. (This field cannot be used with destination.minAmount.)
destination. tag	integer	Optional An arbitrary unsigned 32-bit integer that identifies a reason for payment or a non-Ripple account.
destination. address	address	The address to send to.
destination. minAmount	laxAmount	The minimum amount to be delivered. (This field is exclusive with destination.amount)
allowPartialPayment	boolean	Optional If true, this payment should proceed even if the whole amount cannot be delivered due to a lack of liquidity or a lack of funds in the source account.
invoiceID	string	Optional A 256-bit hash that can be used to identify a particular payment.
limitQuality	boolean	Optional Only take paths where all the conversions have an input:output ratio that is equal or better than the ratio of destination.amount:source.maxAmount.
memos	memos	Optional Array of memos to attach to the transaction.
noDirectRipple	boolean	Optional If true and paths are specified, the sender would like the XRP Ledger to disregard any direct paths from the source account to the destination account. This may be used to take advantage of an arbitrage opportunity or by gateways wishing to issue balances from a hot wallet to a user who has mistakenly set a trustline directly to the hot wallet.
paths	string	Optional The paths of trustlines and orders to use in executing the payment.

immediateOrCancel	boolean	Optional Treat the offer as an Immediate or Cancel order. If enabled, the offer will never become a ledger node: it only attempts to match existing offers in the ledger. This cannot be used with fillOrKill.
memos	memos	Optional Array of memos to attach to the transaction.
orderToReplace	sequence	Optional The account sequence number of an order to cancel before the new order is created, effectively replacing the old order.
passive	boolean	Optional If enabled, the offer will not consume offers that exactly match it, and instead becomes an Offer node in the ledger. It will still consume offers that cross it.

rippled APIs

ripple-lib relies on rippled APIs for all online functionality. With ripple-lib version 1.0.0 and higher, you can easily access rippled APIs through ripple-lib. Use the request(), hasNextPage(), and requestNextPage() methods:

• Use request() to issue any rippled command, including account_currencies, subscribe, and unsubscribe. Full list of API Methods.
• Use hasNextPage() to determine whether a response has more pages. This is true when the response includes a marker field.
• Use requestNextPage() to request the next page of data.

When using rippled APIs:

• Specify XRP amounts in drops.
• Specify timestamps as the number of seconds since the "Ripple Epoch".
• Instead of counterparty, use issuer.

Listening to streams

The rippled server can push updates to your client when various events happen. Refer to Subscriptions in the rippled API docs for details.

Note that the streams parameter for generic streams takes an array. For example, to subscribe to the validations stream, use { streams: [ 'validations' ] }.

The string names of some generic streams to subscribe to are in the table below. (Refer to rippled for an up-to-date list of streams.)

Type	Description
server	Sends a message whenever the status of the rippled server (for example, network connectivity) changes.
ledger	Sends a message whenever the consensus process declares a new validated ledger.
transactions	Sends a message whenever a transaction is included in a closed ledger.
transactions_proposed	Sends a message whenever a transaction is included in a closed ledger, as well as some transactions that have not yet been included in a validated ledger and may never be. Not all proposed transactions appear before validation. Even some transactions that don't succeed are included in validated ledgers because they take the anti-spam transaction fee.
validations	Sends a message whenever the server receives a validation message, also called a validation vote, regardless of whether the server trusts the validator.
manifests	Sends a message whenever the server receives a manifest.
peer_status	(Admin-only) Information about connected peer rippled servers, especially with regards to the consensus process.

When you subscribe to a stream, you must also listen to the relevant message type(s). Some of the available message types are in the table below. (Refer to rippled for an up-to-date list of message types.)

Type	Description
ledgerClosed	Sent by the ledger stream when the consensus process declares a new fully validated ledger. The message identifies the ledger and provides some information about its contents.
validationReceived	Sent by the validations stream when the server receives a validation message, also called a validation vote, regardless of whether the server trusts the validator.
manifestReceived	Sent by the manifests stream when the server receives a manifest.
transaction	Sent by many subscriptions including transactions, transactions_proposed, accounts, accounts_proposed, and book (Order Book). See Transaction Streams for details.
peerStatusChange	(Admin-only) Reports a large amount of information on the activities of other rippled servers to which the server is connected.

To register your listener function, use connection.on(type, handler).

Here is an example of listening for transactions on given account(s):

const account = 'rf1BiGeXwwQoi8Z2ueFYTEXSwuJYfV2Jpn' // Replace with the account you want notifications for
api.connect().then(() => { // Omit this if you are already connected

  // 'transaction' can be replaced with the relevant `type` from the table above
  api.connection.on('transaction', (event) => {

      // Do something useful with `event`
      console.log(JSON.stringify(event, null, 2))
  })

  api.request('subscribe', {
      accounts: [ account ]
  }).then(response => {
      if (response.status === 'success') {
          console.log('Successfully subscribed')
      }
  }).catch(error => {
      // Handle `error`
  })
})

The subscription ends when you unsubscribe or the WebSocket connection is closed.

For full details, see rippled Subscriptions.

request

request(command: string, options: object): Promise<object>

Returns the response from invoking the specified command, with the specified options, on the connected rippled server.

Refer to rippled APIs for commands and options. All XRP amounts must be specified in drops. One drop is equal to 0.000001 XRP. See Specifying Currency Amounts.

Most commands return data for the current (in-progress, open) ledger by default. Do not rely on this. Always specify a ledger version in your request. In the example below, the 'validated' ledger is requested, which is the most recent ledger that has been validated by the whole network. See Specifying Ledgers.

Return Value

This method returns a promise that resolves with the response from rippled.

Example

// Replace 'ledger' with your desired rippled command
return api.request('ledger', {
  ledger_index: 'validated'
}).then(response => {
  /* Do something useful with response */
  console.log(JSON.stringify(response, null, 2))
}).catch(console.error);

hasNextPage

hasNextPage(currentResponse): boolean

Returns true when there are more pages available.

When there are more results than contained in the response, the response includes a marker field. You can use this convenience method, or check for marker yourself.

See Markers and Pagination.

Return Value

This method returns true if currentResponse includes a marker.

Example

return api.request('ledger_data', {
  ledger_index: 'validated'
}).then(response => {
  /* Do something useful with response */

  if (api.hasNextPage(response)) {
    /* There are more pages available */
  }
}).catch(console.error);

requestNextPage

requestNextPage(command: string, params: object = {}, currentResponse: object): Promise<object>

Requests the next page of data.

You can use this convenience method, or include currentResponse.marker in params yourself, when using request.

See Markers and Pagination.

Return Value

This method returns a promise that resolves with the next page of data from rippled.

If the response does not have a next page, the promise will reject with new errors.NotFoundError('response does not have a next page').

Example

const command = 'ledger_data'
const params = {
  ledger_index: 'validated'
}
return api.request(command, params).then(response => {
  return api.requestNextPage(command, params, response)
}).then(response_page_2 => {
  /* Do something useful with second page of response */
}).catch(console.error);

}

getLedger

getLedger(options: Object): Promise<Object>

Returns header information for the specified ledger (or the most recent validated ledger if no ledger is specified). Optionally, all the transactions that were validated in the ledger or the account state information can be returned with the ledger header.

Parameters

Name	Type	Description
options	object	Optional Options affecting what ledger and how much data to return.
options. includeAllData	boolean	Optional Include full transactions and/or state information if includeTransactions and/or includeState is set.
options. includeState	boolean	Optional Return an array of hashes for all state data or an array of all state data in this ledger version, depending on whether includeAllData is set.
options. includeTransactions	boolean	Optional Return an array of hashes for each transaction or an array of all transactions that were validated in this ledger version, depending on whether includeAllData is set.
options. ledgerVersion	integer	Optional Get ledger data for this historical ledger version.
options. ledgerVersion	string	Optional Get ledger data for this historical ledger version.

Return Value

This method returns a promise that resolves with an object with the following structure:

Name	Type	Description
stateHash	string	Hash of all state information in this ledger.
closeTime	date-time string	The time at which this ledger was closed.
closeTimeResolution	integer	Approximate number of seconds between closing one ledger version and closing the next one.
closeFlags	integer	A bit-map of flags relating to the closing of this ledger. Currently, the ledger has only one flag defined for closeFlags: sLCF_NoConsensusTime (value 1). If this flag is enabled, it means that validators were in conflict regarding the correct close time for the ledger, but built otherwise the same ledger, so they declared consensus while "agreeing to disagree" on the close time. In this case, the consensus ledger contains a closeTime value that is 1 second after that of the previous ledger. (In this case, there is no official close time, but the actual real-world close time is probably 3-6 seconds later than the specified closeTime.)
ledgerHash	string	Unique identifying hash of the entire ledger.
ledgerVersion	integer	The ledger version of this ledger.
ledgerVersion	string	The ledger version of this ledger.
parentLedgerHash	string	Unique identifying hash of the ledger that came immediately before this one.
parentCloseTime	date-time string	The time at which the previous ledger was closed.
totalDrops	value	Total number of drops (1/1,000,000th of an XRP) in the network, as a quoted integer. (This decreases as transaction fees cause XRP to be destroyed.)
transactionHash	string	Hash of the transaction information included in this ledger.
rawState	string	Optional A JSON string containing all state data for this ledger in rippled JSON format.
stateHashes	array<string>	Optional An array of hashes of all state data in this ledger.
transactionHashes	array<transactionHash>	Optional An array of hashes of all transactions that were validated in this ledger.
transactions	array<getTransaction>	Optional Array of all transactions that were validated in this ledger. Transactions are represented in the same format as the return value of getTransaction.

Example

return api.getLedger()
  .then(ledger => {/* ... */});

Field mapping: allowCancelAfter is equivalent to rippled's CancelAfter; allowExecuteAfter is equivalent to FinishAfter. At the allowCancelAfter time, the escrow is considered expired. This means that the funds can only be returned to the sender. At the allowExecuteAfter time, the escrow is permitted to be released to the recipient (if the condition is fulfilled).

Note that allowCancelAfter must be chronologically later than allowExecuteAfter.

true

computeLedgerHash

computeLedgerHash(ledger: Object): string

Compute the hash of a ledger.

Parameters

The parameter to this method has the same structure as the return value of getLedger.

Name	Type	Description
ledger	object	The ledger header to hash.
ledger. stateHash	string	Hash of all state information in this ledger.
ledger. closeTime	date-time string	The time at which this ledger was closed.
ledger. closeTimeResolution	integer	Approximate number of seconds between closing one ledger version and closing the next one.
ledger. closeFlags	integer	A bit-map of flags relating to the closing of this ledger. Currently, the ledger has only one flag defined for closeFlags: sLCF_NoConsensusTime (value 1). If this flag is enabled, it means that validators were in conflict regarding the correct close time for the ledger, but built otherwise the same ledger, so they declared consensus while "agreeing to disagree" on the close time. In this case, the consensus ledger contains a closeTime value that is 1 second after that of the previous ledger. (In this case, there is no official close time, but the actual real-world close time is probably 3-6 seconds later than the specified closeTime.)
ledger. ledgerHash	string	Unique identifying hash of the entire ledger.
ledger. ledgerVersion	integer	The ledger version of this ledger.
ledger. ledgerVersion	string	The ledger version of this ledger.
ledger. parentLedgerHash	string	Unique identifying hash of the ledger that came immediately before this one.
ledger. parentCloseTime	date-time string	The time at which the previous ledger was closed.
ledger. totalDrops	value	Total number of drops (1/1,000,000th of an XRP) in the network, as a quoted integer. (This decreases as transaction fees cause XRP to be destroyed.)
ledger. transactionHash	string	Hash of the transaction information included in this ledger.
ledger. rawState	string	Optional A JSON string containing all state data for this ledger in rippled JSON format.
ledger. stateHashes	array<string>	Optional An array of hashes of all state data in this ledger.
ledger. transactionHashes	array<transactionHash>	Optional An array of hashes of all transactions that were validated in this ledger.
ledger. transactions	array<getTransaction>	Optional Array of all transactions that were validated in this ledger. Transactions are represented in the same format as the return value of getTransaction.

Return Value

This method returns an uppercase hexadecimal string representing the hash of the ledger.

Example

const ledger = {
  "stateHash": "D9ABF622DA26EEEE48203085D4BC23B0F77DC6F8724AC33D975DA3CA492D2E44",

API Events

ledger

This event is emitted whenever a new ledger version is validated on the connected server.

Return Value

Name	Type	Description
baseFeeXRP	value	Base fee, in XRP.
ledgerHash	string	Unique hash of the ledger that was closed, as hex.
ledgerTimestamp	date-time string	The time at which this ledger closed.
reserveBaseXRP	value	The minimum reserve, in XRP, that is required for an account.
reserveIncrementXRP	value	The increase in account reserve that is added for each item the account owns, such as offers or trust lines.
transactionCount	integer	Number of new transactions included in this ledger.

Example

api.on('ledger', ledger => {
  console.log(JSON.stringify(ledger, null, 2));
});

}

error

This event is emitted when there is an error on the connection to the server that cannot be associated to a specific request.

Return Value

The first parameter is a string indicating the error type:

• badMessage - rippled returned a malformed message
• websocket - the websocket library emitted an error
• one of the error codes found in the rippled Universal Errors.

The second parameter is a message explaining the error.

The third parameter is:

• the message that caused the error for badMessage
• the error object emitted for websocket
• the parsed response for rippled errors

Example

api.on('error', (errorCode, errorMessage, data) => {
  console.log(errorCode + ': ' + errorMessage);
});

tooBusy: The server is too busy to help you now.

connected

This event is emitted after connection successfully opened.

Example

api.on('connected', () => {
  console.log('Connection is open now.');
});

disconnected

This event is emitted when connection is closed.

Return Value

The only parameter is a number containing the close code send by the server.

Example

api.on('disconnected', (code) => {
  if (code !== 1000) {
    console.log('Connection is closed due to error.');
  } else {
    console.log('Connection is closed normally.');
  }
});
