However, I ran into a few things that I'd like to dedicate this quick post on.
Connecting to the API
The first thing was I ran into the following error:
Turns out it had to do with me connecting to the REST API in an earlier session, but with Windows authentication.
Exceeded Amount of Allowed Requests
Probably because I was not as fast as Parker creating the report, I ran into the following problem :-)
Power BI Desktop wil NOT return an error message, instead it will just keep spinning.. The Try It button on the REST API Documentation site will however return a 429 Response code, saying you have exceeded the amount of allowed requests, and I have to wait (approximately 😀) 1256 seconds.
Refreshable Access Token
In Part 2: Obtaining a Refreshable Access Token Parker explains how to get past the point of entering your Bearer token everytime it expires :-)
Limit The Number of API Calls
Another important point was made by Marc Lelijveld ( b | @MarcLelijveld), he suggests to use the $expand parameter of the GetGroupsAsAdmin function. That way you don't have to query the API every time per dataset/dataflow/etc.
You can check a few examples of the use of $expand at the documentation of the Admin- Groups GetGroupsAsAdmin page.
I hope reading this will help you in better setting up management of your Power BI environment.
