Dataverse Web API Actions Authenticated via Custom Connector

Posted on by davidyc

Does anyone know how to configure a Custom Connector to use the Dataverse Web API? I would like to use the actions to create columns and tables.

I understand the principles and code flow for OAuth 2.0, however it seems that implementing it within the custom connector is troublesome. I have researched heavily the topic specifically and conducted many tests. I am getting a very unhelpful 401 error and I'm running out of things to try and change - I have researched and tested:

azure app registration, including the tweaks of the manifest, app permission incl. User Impersonation and Dynamics CRM etc
azure active directory authentication type in custom connector, using the azure app client secret & id, correct refresh url

Links referenced include:

Authenticate your API and connector with Azure Active Directory - Azure AD | Microsoft Docs

Authenticate against Dataverse by using OAuth - Learn | Microsoft Docs

Any help much appreciated.

Hi @davidyc,

Have you tested via Postman that you can successfully retrieve an access token and then successfully call the Dataverse Web API using the access token?

Luckily I changed the Resource URL and it is now working perfectly within the Custom Connector for Dataverse... Thanks for the response!
