When you import your PBIX file into your Power BI workspace collection on Azure the service does not include your credentials due to security concerns. After your import is complete you can modify the credentials and / or connection strings using our REST APIs.
Power BI REST APIs
Specifically you'll need to call the PATCH datasource API Patch Gateway Datasource API
Examples of calling these APIs via the SDKs can be found in the following:
- .NET Provision Tool from sample (Update Connection)
- Node JS Command Line tool (Update Connection)
