Then initialize without parameters:

import SapClient from 'sap-integration-suite-client';
import dotenv from 'dotenv';
dotenv.config();

const client = new SapClient(); // Reads from process.env

Direct Configuration

import SapClient from 'sap-integration-suite-client';

const client = new SapClient({
  baseUrl: 'https://your-tenant.integrationsuitetrial-api.eu10.hana.ondemand.com/api/v1',
  oauthClientId: 'your-client-id',
  oauthClientSecret: 'your-client-secret',
  oauthTokenUrl: 'https://your-tenant.authentication.eu10.hana.ondemand.com/oauth/token',
  
  // Optional settings

📚 API Examples

Integration Content Example

Manage integration packages, flows, and other artifacts:

import SapClient from 'sap-integration-suite-client';

const client = new SapClient();

async function managePackages() {
  // List packages (with pagination)
  const packages = await client.integrationContent.getIntegrationPackages({ top: 5 });
  console.log(`Found ${packages.length} packages`);
  
  if (packages.length > 0) {
    const packageId = packages[0].Id;
    
    // Get integration flows in a package
    const flows = await client.integrationContent.getIntegrationFlows(packageId);
    console.log(`Package ${packages[0].Name} has ${flows.length} integration flows`);
    
    // Get a specific flow
    if (flows.length > 0) {
      const flow = await client.integrationContent.getIntegrationFlowById(flows[0].Id);
      console.log(`Flow details: ${flow?.Name}, Version: ${flow?.Version}`);
    }
  }
}

managePackages().catch(console.error);

Message Processing Logs Example

Monitor and analyze message execution:

import SapClient from 'sap-integration-suite-client';

const client = new SapClient();

async function monitorMessages() {
  // Get failed messages from the last 24 hours
  const yesterday = new Date();
  yesterday.setDate(yesterday.getDate() - 1);
  
  const { logs } = await client.messageProcessingLogs.getMessageProcessingLogs({
    filter: `Status eq 'FAILED' and LogEnd gt datetime'${yesterday.toISOString()}'`,
    top: 10,
    orderby: ['LogEnd desc']
  });
  
  console.log(`Found ${logs.length} failed messages in the last 24 hours`);
  
  for (const log of logs) {
    console.log(`Message: ${log.MessageGuid}, Flow: ${log.IntegrationFlowName}`);
    
    // Get error details for a failed message
    const errorInfo = await client.messageProcessingLogs.getLogErrorInformation(log.MessageGuid);
    if (errorInfo) {
      console.log(`Error: ${errorInfo.ErrorMessage}`);
    }
  }
}

monitorMessages().catch(console.error);

Security Content Example

Manage security artifacts like keystores and credentials:

import SapClient from 'sap-integration-suite-client';

const client = new SapClient();

async function manageKeystore() {
  // List keystore entries
  const entries = await client.securityContent.getKeystoreEntries('system');
  console.log(`Found ${entries.length} entries in the system keystore`);
  
  entries.forEach(entry => {
    console.log(`- ${entry.Alias} (${entry.Type}), Valid until: ${entry.Validity}`);
  });
}

manageKeystore().catch(console.error);

Message Store Example

Access persisted messages and their payloads:

import SapClient from 'sap-integration-suite-client';

const client = new SapClient();

async function accessMessageStore(messageGuid: string) {
  // Get store entries for a message
  const entries = await client.messageStore.getMessageStoreEntriesForMessage(messageGuid);
  console.log(`Found ${entries.length} message store entries`);
  
  if (entries.length > 0) {
    // Get entry details
    console.log(`Entry ID: ${entries[0].Id}, Type: ${entries[0].MsgType}`);
    
    // Get payload (if available)
    try {
      const payload = await client.messageStore.getMessageStoreEntryPayload(entries[0].Id);
      console.log('Payload retrieved successfully');
    } catch (error) {
      console.error('Failed to retrieve payload');
    }
  }
}

// Replace with a valid message GUID
accessMessageStore('your-message-guid').catch(console.error);

Log Files Example

Access HTTP and trace logs:

import SapClient from 'sap-integration-suite-client';

const client = new SapClient();

async function accessLogs() {
  // List HTTP log files
  const logs = await client.logFiles.getLogFiles({ 
    filter: "LogFileType eq 'http'"
  });
  
  console.log(`Found ${logs.length} HTTP log files`);
  
  if (logs.length > 0) {
    const recentLog = logs[0];
    console.log(`Recent log: ${recentLog.Name}, Size: ${recentLog.Size} bytes`);
    
    // Download log content
    if (recentLog.Name && recentLog.Application) {
      const content = await client.logFiles.downloadLogFile(
        recentLog.Name, 
        recentLog.Application
      );
      
      // In Node.js, convert content to string
      if (Buffer.isBuffer(content)) {
        const textContent = content.toString('utf-8').substring(0, 500);
        console.log(`Log content preview: ${textContent}...`);
      }
    }
  }
}

accessLogs().catch(console.error);

🔧 Advanced Features

Integration Content Advanced Example

The library provides advanced clients with enhanced capabilities:

import SapClient from 'sap-integration-suite-client';

const client = new SapClient();

async function advancedOperations() {
  // Get packages with all their artifacts in a single operation
  const packagesWithArtifacts = await client.integrationContentAdvanced.getPackagesWithArtifacts({
    top: 5,
    includeEmpty: false,  // Skip packages without artifacts
    parallel: true        // Use parallel requests for better performance
  });
  
  console.log(`Retrieved ${packagesWithArtifacts.length} packages with their artifacts`);
  
  // Example of data available
  if (packagesWithArtifacts.length > 0) {
    const pkg = packagesWithArtifacts[0];
    console.log(`Package: ${pkg.package.Name} (${pkg.package.Id})`);
    console.log(`- Integration Flows: ${pkg.artifacts.integrationFlows.length}`);
    console.log(`- Value Mappings: ${pkg.artifacts.valueMappings.length}`);
    console.log(`- Message Mappings: ${pkg.artifacts.messageMappings.length}`);
    console.log(`- Script Collections: ${pkg.artifacts.scriptCollections.length}`);
  }
}

advancedOperations().catch(console.error);

Extending Your Project

You can extend the library with custom functionality without modifying the node_modules directory:

// src/custom/FlowAnalytics.ts
import { 
  BaseCustomClient, 
  MessageProcessingLogsClient 
} from 'sap-integration-suite-client';

// Create your custom client class
export class FlowAnalytics extends BaseCustomClient<MessageProcessingLogsClient> {
  async getFlowPerformance(flowName: string, days = 7) {
    const fromDate = new Date();
    fromDate.setDate(fromDate.getDate() - days);
    
    const { logs } = await this.client.getMessageProcessingLogs({
      filter: `IntegrationFlowName eq '${flowName}' and Status eq 'COMPLETED' and LogEnd gt datetime'${fromDate.toISOString()}'`,
      top: 100
    });
    
    // Calculate performance metrics
    const durations = logs.map(log => {
      const start = new Date(log.LogStart).getTime();
      const end = new Date(log.LogEnd).getTime();
      return end - start;
    });
    
    return {
      count: logs.length,
      avgDuration: durations.reduce((sum, d) => sum + d, 0) / durations.length || 0,
      minDuration: Math.min(...durations) || 0,
      maxDuration: Math.max(...durations) || 0
    };
  }
}

// src/custom/FlowAnalyticsFactory.ts
import { CustomClientFactory, MessageProcessingLogsClient } from 'sap-integration-suite-client';
import { FlowAnalytics } from './FlowAnalytics';

export class FlowAnalyticsFactory implements CustomClientFactory<MessageProcessingLogsClient, FlowAnalytics> {
  create(baseClient: MessageProcessingLogsClient): FlowAnalytics {
    return new FlowAnalytics(baseClient);
  }
}

// src/index.ts - Using your custom client
import SapClient from 'sap-integration-suite-client';
import { FlowAnalyticsFactory } from './custom/FlowAnalyticsFactory';

const client = new SapClient();

// Register your custom factory
client.customClientRegistry.registerFactory('flow-analytics', new FlowAnalyticsFactory());

// Use your custom client
async function analyzeFlowPerformance() {
  const analytics = client.customClientRegistry.create('flow-analytics', client.messageProcessingLogs);
  
  const performance = await analytics.getFlowPerformance('MyIntegrationFlow');
  console.log('Flow performance:', performance);
}

analyzeFlowPerformance().catch(console.error);

🎣 Error Handling

The client provides enhanced error objects with additional details:

import SapClient from 'sap-integration-suite-client';

const client = new SapClient();

async function handleErrors() {
  try {
    // Try to get a non-existent package
    await client.integrationContent.getIntegrationPackageById('non-existent-id');
  } catch (error: any) {
    console.error('Error occurred:');
    console.error(`- Status Code: ${error.statusCode || 'N/A'}`);
    console.error(`- Status Text: ${error.statusText || 'N/A'}`);
    console.error(`- Message: ${error.message}`);
    
    // SAP specific error details (if available)
    if (error.responseData) {
      console.error('- SAP Error:', error.responseData);
    }
  }
}

handleErrors();

❓ Troubleshooting

Common issues and solutions:

Authentication Problems

• OAuth Errors: Verify your Client ID, Client Secret, and Token URL
• Permission Errors: Ensure your OAuth client has the necessary roles assigned (IntegrationDeveloper, etc.)

API Errors

• 404 Not Found: Check that your baseUrl is correct and includes /api/v1
• 403 Forbidden: Your client might lack necessary permissions for the API
• CSRF Token Errors: Ensure your base URL is correct and allows token fetch operations

Environment-Specific Issues

• Neo vs. Cloud Foundry: Some APIs are environment-specific (Neo-only or CF-only)
• Tenant Configuration: Verify your tenant has the APIs you need enabled
