How to generate a token for PowerBI? - json

Question

i'm actually lost in the See of information. i have found a lot of Resources like this page but NONE works for some reason. so i have already created an AD app for PowerBI using the Power BI embedding setup tool. I choose the Embed Power BI for your organization's internal users—for enterprises.
i didn't know what i should have given as home page URL so i typed a local host which i think is what that's messing everything up.
then i gave all the permissions it needs at the end i got this:
so my problem is that i want to Refresh a specific Dataset with HTTP request tool in a Logic app. the link looks like this:
https://api.powerbi.com/v1.0/myorg/groups/{G_id}/datasets/{D_id}/refresh
but i found out before that i need a token for it because it returns 403 Forbidden Error. so i read Docs and got lost. i tried This Page which suggests this request:
POST: https://login.microsoftonline.com/common/oauth2/token
data: {
grant_type: password
scope: openid
resource: https://analysis.windows.net/powerbi/api
client_id: {Client ID} (got this from Azure Active Directory app)
username: {PBI Account Username} (I used email and User from the Picture above but did's work)
password: {PBI Account Username} (I used email and User from the Picture above but did's work)
}
when i tried it, it return this error:
{
"error": "invalid_request",
"error_description": "AADSTS900144: The request body must contain the following parameter: 'grant_type'.\r\nTrace ID: 247iop60-42-407f-a184-1e15e500\r\nCorrelation ID: f3ca10-d034b7-13-50747a3e\r\nTimestamp: 2022-08-17 11:40:05Z",
"error_codes": [
900144
],
"timestamp": "2022-08-17 11:40:05Z",
"trace_id": "2473f960-3a42-407f-a184-1e15eb24d500",

"error_uri": "https://login.microsoftonline.com/error?code=900144"
}
maybe i'm doing sth in Postman App wrong:

Answer 1

I tried to reproduce the same in my environment and got the same error as below:
POST: https://login.microsoftonline.com/common/oauth2/token
data: {
grant_type: password
scope: openid
resource: https://analysis.windows.net/powerbi/api
client_id: {Client ID}
username: {Username}
password: {Username}
}
Response:
To resolve the error, you need to give the parameters in x-www-form-urlencoded like below:
Make sure to give App secret in client_secret parameter.
I got the tokens for PowerBI successfully like below:
After generating the tokens try refreshing the dataset with HTTP request tool in a Logic app.
