Migrating from Web Service Authentication to Oauth?

(0) Share

Posted on by Community Member

Our organization uses Powerapps and Power Automate 'Flows' that connect to Business Central API using a custom connector. We've been informed that the Web Service Authentication (also known as a 'raw' or 'basic' connection) will be expiring soon. We would like to move to Oauth 2.0 for our API connections.

We've begun following documentation for Registering an Application with MS identity platform, however many things are unclear:

Which platform type should be selected for use with Powerapps / Custom Connectors?
Which redirect URI should be used once a platform is selected?
Will the same configuration work for both Powerapps and Power Automate, or will we need to register 2 separate Apps in Azure AD?

I have the same question (0)

Web. I’d use this blog to help: www.kauffmann.nl/.../

Only need this for PowerApps I believe. Although I’d check the connector settings before dealing with the above. Custom api pages already appear in the list for power automate. The api’s are broken into categories. The api group and api author properties you have on the AL object form part of the category folder. Meaning you don’t have to deal with custom connectors all the time.

Yun Zhu - I've followed your guide but still have 2 questions:

What information should be populated in the custom connector fields below after setting up App Registration in Azure? And is the redirect URI you provided in your guide - https://localhost:8080/login - still correct for this use?
