Power BI REST API to return response in browser

smpa01 — Wed, 20 Apr 2022 14:15:00 GMT

If I host my data model in a premium capacity workspace, is it possible for me to run any endpoint/REST API to return the result of a DAX query in a browser, for example

something like

https://api.powerbi.com/v1.0/myorg/datasets/{datasetId}/EVALUATE VALUES(Org[Mgr])

I went through Announcing the public preview of Power BI REST API support for DAX Queries and Datasets - Execute Queries and did not find anything.

I am simply trying to understand if there is a way for me to fetch the data (of the multidimensional data model) from the SSAS server outside of Power BI environment. If I can access the dataset externally (outside of Power BI), I can further process the data to my req (for example, developing visualization using other languages to display the viz in a browser and let my audience consume it through the browser).

So you cannot do a GET request like the example you posted, but the first link you posted shows how you can do a POST request to get back a JSON response. The only "extra" bit to be aware of is that you have authenticate against PowerBI to make sure that the user has access to the dataset. There is some example c# code for a console app linked in that article, but that should not be too hard to convert to an Azure function or something that you could run on heroku that would then either prompt the user to login or use their existing credentials if they are already logged in.
