How to refresh Datasets with PowerBI REST API - executed in Azure Data Factory Pipeline

[Robinator]

Hi,

I've built multiple pipelines in Azure data factory and a few Power BI reports (https://app.powerbi.com) that use data from those pipelines. My ultimate goal is to be able to refresh a Power BI data set at the end of a pipeline. Underneath I'll show a small selection of what i've read and tried so far.

I started by registrating at https://dev.powerbi.com/apps and with API Acces "Select All". I checked in the azure portal the app registrations. I registrated twice because i was not sure if the oauth20 (following @konstantinos) would screw thing up: 

Then I started in Azure data factory, but after a while (of having failures) I started using Fiddler to send the HTTP Post request. 

I use the logic described at https://docs.microsoft.com/en-us/rest/api/power-bi/datasets/refreshdatasetingroup. It says: 

"POST https://api.powerbi.com/v1.0/myorg/groups/{groupId}/datasets/{datasetKey}/refreshes"

I get my group and dataset ID at https://app.powerbi.com/.... 

->  https://api.powerbi.com/v1.0/myorg/groups/ecb52bc1-........................../datasets/ab5d2d28-.......

I copy this link into Fiddler: 

My best guess would be that i should include authentication into the request body, although i cant find examples online. 

Eventually I want to refresh the dataset  from a 'web' container in ADF. Although, lets start succesfully refreshing something first 🙂

Gonna try this solution. Magic search word = Postman

yaay, some small progress

gonna try creating a powershell script and run that script in ADF using a webhook,

Used the following as Powershell script, and it worked  

$authUrl = "https://login.windows.net/common/oauth2/token/"

$body = @{

"resource" = "https://analysis.windows.net/powerbi/api";

"client_id" = "bf..........";

"grant_type" = "password";

"username" = ".......@........."; 

"password" = ".............";

"scope" = "openid"

}

$authResponse = Invoke-RestMethod -Uri $authUrl –Method POST -Body $body

$headers = @{

"Content-Type" = "application/json";

"Authorization" = $authResponse.token_type + " " +

$authResponse.access_token

}

$restURL = "https://api.powerbi.com/v1.0/myorg/groups"

$restResponse = Invoke-RestMethod -Uri $restURL –Method GET -Headers $headers

$datasetId = "ab5d......."

$groupId = "ecb5......"

$restUrl = "https://api.powerbi.com/v1.0/myorg/groups/$groupId/datasets/$datasetId/refreshes"

$body = @{

"notifyOption"= "MailOnFailure"

}

$restResponse = Invoke-RestMethod -Uri $restUrl –Method POST -Headers $headers -Body $body
