Applies to Product - Microsoft Dataverse
What’s happening?
The request body must contain the following parameter: 'grant_type'. This error occurs when attempting to request an OAuth Access token from Dataverse using a format that does not include the required parameters.
Reason:
The OAUTH 2.0 specification, which Azure Active Directory (AAD) follows, requires parameters to be sent in the application/x-www-form-urlencoded format. Sending parameters in raw JSON or XML format is not supported by the protocol.

Resolution:
To resolve this, modify the request body to include the "grant_type" parameter with the value "client_credentials". The request should be structured as follows:
json { "grant_type": "client_credentials", "client_id": "{{client_id}}", "client_secret": "{{client_secret}}", "scope": "https://graph.microsoft.com/.default" }
Make sure to replace {{client_id}} and {{client_secret}} with the appropriate values for your application. This adjustment will allow you to obtain the access token in the correct format for accessing the API. Additionally, refer to the official Microsoft documentation for further guidance: Microsoft Documentation.
