| # DAX API | ||
|
|
||
| The DAX API enables Cube to connect to [Microsoft Power BI][ref-powerbi]. | ||
| It derives its name from [data analysis expressions][link-dax], a query language | ||
| for Power BI and SQL Server Analysis Services. | ||
|
|
||
| Unlike the [SQL API][ref-sql-api], it provides a native experience and superior | ||
| support for Power BI features. | ||
|
|
||
| <SuccessBox> | ||
|
|
||
| The DAX API is available in Cube Cloud on [Enterprise and above](https://cube.dev/pricing) product tiers. | ||
| It also requires the M [deployment tier](/product/deployment/cloud/pricing#deployment-tiers). | ||
|
|
||
| </SuccessBox> | ||
|
|
||
| <WarningBox> | ||
|
|
||
| The DAX API is currently in preview. Please [contact us](https://cube.dev/contact) to enable it for your account. | ||
|
|
||
| </WarningBox> | ||
|
|
||
| Read below about the DAX API [configuration](#configuration), | ||
| [authentication](#authentication), and [using it](#using-dax-api-with-power-bi) with Power BI. | ||
|
|
||
| See the [DAX API reference][ref-ref-dax-api] for the list of supported DAX functions. | ||

|
||
| ## Configuration | ||
|
|
||
| <WarningBox> | ||
|
|
||
| Please contact the customer success team in Cube Cloud so we can guide you | ||
| through the configuration. | ||
|
|
||
| </WarningBox> | ||
|
|
||
| To enable or disable the DAX API on a specific deployment, go to <Btn>Settings</Btn> | ||
| in the Cube Cloud sidebar, then <Btn>Configuration</Btn>, and then toggle the | ||
| <Btn>Enable DAX API</Btn> option. | ||
|
|
||
| ## Authentication | ||
|
|
||
| The DAX API supports the user name and password authentication method. | ||
|
|
||
| ## Using DAX API with Power BI | ||
|
|
||
| <InfoBox> | ||
|
|
||
| The DAX API works only with [views][ref-views], not cubes. | ||
|

| ### Connection methods | ||
|
|
||
| Power BI provides [three methods][link-powerbi-connection] to connect to data | ||
| sources: _live connection_, _DirectQuery_, and _import mode_. | ||
|
|
||
| | | Live connection | DirectQuery | <nobr>Import mode</nobr> | | ||
| | --- | --- | --- | --- | | ||
| | Data location | 🟢 Data source | 🟢 Data source | 🟡 Power BI | | ||
| | Data freshness | 🟢 Real-time data | 🟢 Real-time data | 🟡 Stale copy | | ||
| | Semantic model | <nobr>🟢 Up-to-date model</nobr> | 🟡 Stale copy | 🟡 Stale copy | | ||
| | Queries | <nobr>🟢 Composed in UI</nobr><br/><nobr>🔴 No custom queries</nobr> | <nobr>🟢 Composed in UI</nobr><br/><nobr>🟢 Custom queries</nobr> | <nobr>🟢 Composed in UI</nobr><br/><nobr>🟢 Custom queries</nobr> | | ||
|
|
||
| __It's recommended to use a _live connection_ whenever possible.__ Use _DirectQuery_ | ||
| if you need to write your own DAX queries, but be aware that you must manually | ||
| synchronize semantic models as they evolve. _Import mode_ is not recommended, as | ||
| it removes the benefits of using a semantic layer. | ||
