Connecting to REST API - Trouble authenticating

[kasiaw29]

Hi community,

I'm trying to connect to some REST API's to get data on my PowerBI Workspaces activity in order to get Usage Metrics but per whole real estate. 

I'm using a function that gets a refreshable access token, when it's invoked and refreshed it returns a new token. 

Then I'm passing it into my Queries for workspaces, datasets and reports

but I'm getting this when it's asking me to specify how to connect:

So somewhere it is failing on passing the access token through. Has anyone tried to accomplish what I'm trying before? Did you run into the same issue? Can you help a girl out, please? 

Thanks,

Kasia

thank you so much

Hey @allan_oliveira 

Sure so what I did is created 3 parameters where I stored my App ID, Tenant ID and App Secret 

You can do that by going to Manage Parameters at the top and create a new to store those details. 

Then I have created Get Access Token function, using this code: 

() =>

let
    body = "client_id=" & #"App ID" 
    & "&scope=https://analysis.windows.net/powerbi/api/.default&client_secret=" & #"App Secret" 
    & "&grant_type=client_credentials",
    Data= Json.Document(Web.Contents("https://login.microsoftonline.com/"& TenantID & "/oauth2/v2.0/token/", 
    [Headers=[#"Content-Type"="application/x-www-form-urlencoded"], Content=Text.ToBinary(body)])),
    access_token = Data[access_token]
in
    access_token

As you can see I'm referencing my parameters in the code. 

To test that this works for you press Invoke and you should get a long string with token passing through. You can refresh it and you'll see each time it returns a fresh token. 

This is as far as I have it working, my issue is passing it into workspace code...it's having trouble authenticating:

Hi @kasiaw29 

I have a test on your access token code, it works well.

I think you meet problem when you use this token to get result in your workspace code. You can try to use Web connector to connect to your Group API and then change the access token to dynamic in Advance Editor.

For more details, you may refer to this video and you can try the way in this video to get access token too.
