Power BI Report Builder - WEB Connector - Advanced Options (HTTP request header parameters)

[Luiz_Grillo]

I’d like to request the addition of support for custom HTTP request headers in Power BI Report Builder, similar to what is already available in Power BI Desktop.

Currently, when connecting to APIs in Power BI Report Builder, there is no option to include request headers (for example, Authorization: Bearer <token>). This limitation makes it impossible to connect to APIs that require authentication, which is a very common use case.

In contrast, Power BI Desktop already provides this capability, making it much easier to work with APIs that need authentication or other custom headers.

Hi @Luiz_Grillo 

You are right – Power BI Report Builder does not currently support adding custom HTTP request headers in the Web connector, unlike Power BI Desktop.
This limitation makes it difficult to connect directly to APIs that require authentication (e.g., Authorization: Bearer <token>) or other custom headers.

The current workarounds are either to use Power BI Desktop and then publish the dataset, or to configure an intermediate proxy that injects the required headers.

Opening a new Idea in the Fabric Ideas forum would be the right way to request this capability so the product team can evaluate and prioritize it.

Power BI Report Builder doesn’t support custom HTTP headers like Authorization: Bearer <token>, making it hard to connect to authenticated APIs. Power BI Desktop does support this, so for now, use Desktop or raise a feature request to Microsoft to close the gap.
