Posted on by VenkyKrishnan1

Im trying to access my Dynamics instance via an API.

* I setup a Demo instance of Dynamics (in my Azure subscription). I then tried to access (in AAD) the Web API via Postman. When I try to Grant Permissions, I tried adding Dynamics CRM and failed. I get an error message that I do not have a Dynamics instance in that subscription.

What am i doing wrong?

thanks.

You're asking in a Dynamics 365 Forum, but talking about Dynamics CRM. You're either in a wrong forum or you're trying to do a wrong thing.

If you want to test the WEB API in Dynamics 365 CRM using Postman, here’s what you need to do to setup Postman to connect to Dynamics 365’s Web API
There are 2 parts to this setup –

Registering an App in Active Directory.

Configuring Postman to utilize the App to connect to Dynamics 365.

Prerequisites:

-Verify Dynamics instance creation: Double-check that you have successfully created a Dynamics instance in your Azure subscription. Make sure you have followed the correct steps to provision the instance and that it is properly set up and running.

-Check subscription and environment: Ensure that you are using the correct Azure subscription and environment when attempting to add Dynamics CRM in AAD. It's possible that you might have multiple subscriptions or environments, and you need to select the right one.
-Confirm permissions and roles: Ensure that you have the necessary permissions and roles in your Azure subscription to manage resources and configure AAD settings. You might need to be a global administrator or have specific roles assigned to perform certain actions.

-Refresh AAD and clear cache: If you recently created the Dynamics instance, it might take some time for AAD to recognize the new resource. Try refreshing the page or clearing your browser cache to see if that resolves the issue.

-Troubleshoot connectivity: Check your network connectivity and ensure that you can access the Dynamics instance and AAD endpoints. If you are behind a firewall or using a proxy, make sure it allows the necessary connections.

-Review documentation and seek support: Consult the official documentation provided by Microsoft for setting up Dynamics instances and integrating with AAD. If the issue persists, consider reaching out to Microsoft support for further assistance, as they can provide more specific guidance based on your setup and environment.
