Power BI API return 401 Unauthorized` response

Hello Everybody, 

I have a problem with a Power BI API

 

First i get the Token:

 

 

$url = 'https://login.windows.net/' . $directoryIdAzure . '/oauth2/token'
            /** @var GuzzleHttp\Client $client **/
            $response = $client->post(
                $url,
                [
                    "headers" => [
                        "Accept" => "application/json"
                    ],
                    'form_params' => [
                        'resource'      => 'https://analysis.windows.net/powerbi/api',
                        'client_id'     => $clientIdAzure,
                        'client_secret' => $clientSecretAzure,
                        'grant_type'    => 'client_credentials',
                        'username'      => $user,
                        'password'      => $pass,
                        'scope'         => 'openid',
                    ]
                ]
            );

            $body = json_decode($response->getBody()->getContents(), true);

            $token = $body['access_token'];

 

After i need list all Workspaces using a token

 

 

            $client2 = new \GuzzleHttp\Client();
            $res = $client2->request(
                'GET',
                'https://api.powerbi.com/v1.0/myorg/groups',
                [
                    'headers' =>
                    [
                        'Authorization' => 'Bearer ' . $token,
                        'Accept' => 'application/json',
                        'Content-type' => 'application/json'
                    ]
                ]
            );

            $workspaces = json_decode($res->getBody()->getContents(), true);

 

Return this error for me:

 

"Client error: `GET https://api.powerbi.com/v1.0/myorg/groups` resulted in a `401 Unauthorized` response"

 

The permissions in the Azure it's OK:

I Solved my problem.

 

I change 

'grant_type'    => 'client_credentials',

 

to 

 

'grant_type'    => 'password',

 

and I had to disable Security Defaults in the Azure 

Azure Portal > Azure AD > Properties > Click on Manage Security Defaults link > Toggle Enable Security Defaults button to NO.

 

I hope thats help anyone.

You also need to enable use of the Fabric API within the Developer settings of your Power BI tenant.  See ths link for details:  https://learn.microsoft.com/en-us/power-bi/developer/embedded/embed-service-principal
