[Microsoft Power BI][link-powerbi] is a popular business intelligence tool.

Cube Cloud works with both [Power BI Desktop and Power BI Service][link-powerbi-desktop-vs-service].
If you're using Power BI Service, you need to set up an [on-premises data gateway][link-powerbi-gateway].

## Connect to the DAX API

Cube Cloud provides the [DAX API][ref-dax-api] for the native Power BI connectivity.


In Power BI Desktop, choose the **SQL Server Analysis Services database** option
when connecting to a data source. Then, enter the DAX API credentials and choose
**Windows** authentication. It accommodates both [Kerberos][ref-kerberos] and
[NTLM][ref-ntlm] methods.

To find your DAX API credentials, go to the [Integrations][ref-integrations-apis] page,
click **API credentials**, and choose the **DAX API** tab. Use the full DAX API URL,
including the `/cubejs-api/v2/dax` path, as the server name — with a bare hostname, the
client tries to reach an Analysis Services instance on TCP port 2383 and fails to
connect.

Authentication for the DAX API — the XMLA service account, NTLM credentials, and
Kerberos assets — is configured on the **Settings → Power BI** page of your deployment.

### Authentication methods

Cube Cloud supports the following authentication methods for Power BI:

| Application | Authentication | Notes |
| --- | --- | --- |
| Power BI Desktop | [NTLM][ref-ntlm-desktop] | 🟡 Works well for testing purposes |
| Power BI Desktop | [Kerberos][ref-kerberos] | 🟢 Recommended for production |
| Power BI Service | [NTLM][ref-ntlm] + [Kerberos][ref-kerberos] | 🟢 Recommended for production.<br/>Requires [on-premises data gateway][ref-opdg] |

### Connection methods

Cube uses Power BI's [_live connection_][link-powerbi-live] mode. You compose
queries using the Power BI UI, and they run against your Cube semantic model in
real time, so you always work with up-to-date data and an up-to-date model.

<Warning>

Power BI's other connection methods, [_DirectQuery_][link-powerbi-directquery]
and _import mode_, are not supported. Because writing your own DAX queries
requires _DirectQuery_, custom DAX queries are not supported either.

</Warning>

## Connect to the SQL API

You can connect a Cube deployment to Power BI using the [SQL API][ref-sql-api]
as if Cube is a Postgres database. It would provide much more limited functionality
than the DAX API. However, this is the only option when using Cube Core.
