Trigger a Data connection refresh through API

[Anonymous]

Hi All ,

I am new to power bi and trying to triggger a data connection referesh using API.  I have gone through the link 

Datasets - Refresh Dataset - REST API (Power BI Power BI REST APIs) | Microsoft Learn

Unfortunately when i try to execute the api post call through browser , i am getting the below error. 

Access to api.powerbi.com was denied

You don't have authorization to view this page.

HTTP ERROR 403

Can someone guide me how to proceed or implement the API feature here.

Hi @Anonymous ,

A 403 error can occur for any of the following reasons. A fiddler capture may be required to investigate further.

• The user has exceeded the amount of embed token that can be generated on a shared capacity. Purchase Azure capacities to generate embed tokens and assign the workspace to that capacity. 
• The Azure AD auth token expired.
• The authenticated user isn't a member of the group (workspace).
• The authenticated user isn't an admin of the group (workspace).
• The authenticated user doesn't have permissions. Permissions can be updated using refreshUserPermissions API
• The authorization header may not be listed correctly. Make sure there are no typos.

Thanks again for the response.  Is there any guidelines or docs for creating a new user for executing power bi API or do we need to register an app in AD to do all these? i dont want to use my own id to call the API , Any reference or steps to followed for the below steps

1) Create a Servcie account or app  registration in AD ( which ever the best practice)

2) Any setup needs to be done in power bi for the service account?

3) How to obtain a access token using those account.

I have created an app using Embed for your organization for executing the API in ad directory.  I have generated the token using client id and client secret from the new app, i even added the permission for read & write all datasets . but still getting 403 error.

[Anonymous]

i have used my existing cliend id and client secret where i have registered an app for pulling data from AD directory , i have used the same credentials for the below code

#import msal
import requests
import json
import os
from adal import AuthenticationContext

def main():

client_id='xxxxx'
resource = 'ZZZZZ'
username = 'youraccount@domain.com'
tenantname = 'YYYYYY'
client_secret = 'GGGGGG'
password = 'YourMegaSafePassword738!*'
authority_url = 'https://login.microsoftonline.com/yourdomain.com'
scope = ["https://analysis.windows.net/powerbi/api/.default"]
url_groups = 'https://api.powerbi.com/v1.0/myorg/groups'

#msal to obtain the token - TBD !!!!
#app = msal.PublicClientApplication(client_id, authority=authority_url)
#result = app.acquire_token_by_username_password(username=username,password=password,scopes=scope)

auth_context = AuthenticationContext('https://login.microsoftonline.com/' +tenantname)
token = auth_context.acquire_token_with_client_credentials(resource=resource, client_id=client_id,client_secret=client_secret)
print('DEBUG', token)
accessToken = "test"
tokenType = token['tokenType']


refresh_url = 'https://api.powerbi.com/v1.0/myorg/datasets/{datasetid}/refreshes'
header = {"referer": "https://learn.microsoft.com/", "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.0.0 Safari/537.36 Edg/107.0.1418.62", "Content-Type":"application/json","Authorization": f"Bearer {accessToken}"}
payload = {"notifyOption":""}
print('header', header)
response = requests.post(url=refresh_url, data=payload, headers=header)
print('response', response) #response.json())

#os.system("pause")

if __name__ == '__main__':
main()

Can you guide me , is there any step where i need to do a app registration in AD directory for power bi . i believe i am missing something with app registration and obtaining the access token.

I am trying to get the access token or some way of login using python and submit the post request using python.

Hi @Anonymous ,

Do you want to connect to Power BI REST API in Power BI Desktop and you will get 403 errror?

Firstly, we need to get Access token in Power BI Desktop. We will get access token from Power BI by below code.

Please replace the parameters like "client_id","APP ID" and so on by correct values.

() =>

 

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

OR

() =>

 

let

    body =  "&grant_type=Password&resource = https://analysis.windows.net/powerbi/api

&client_id=*****&username=*****&password=*****",

    
 Data=Json.Document(Web.Contents("https://login.microsoftonline.com/common/oauth2/v2.0/token/",

    [Headers=[#"Content-Type"="application/x-www-form-urlencoded"], Content=Text.ToBinary(body)])),

    access_token = Data[access_token]

in

    access_token

Then you can follow this video to get data from the Rest API by access token in first step. 

Finally, you can replace bear token by the access token parameter. 

It will refresh every time your refresh your report.
