Azure API Management OAuth2 Redirect Uri is null

Question

I am trying to add an OAuth2 service to my Azure Api Management service (consumption plan) but the Authorization code grant flow redirect uri is being set to null/signin-oauth/code/callback/{name}

On the "Add OAuth2 service" tab I set the name and id of the oauth2 service (in this example its "test1")

The auto generated redirect uri is then set to null/signin-oauth/code/callback/test1

I know what the redirect uri should be - https://{my-api-management-service-name}.developer.azure-api.net/signin-oauth/code/callback/test1. When calling this I get a server not found error. So it looks like it's not being set up.

It seems to work on anything other than the consumption plan.

Answer 1

Turns out I was following the wrong guide.

I was using the Protect a web API backend in Azure API Management by using OAuth 2.0 authorization with Azure AD when I should have been using the Protect SPA backend with OAuth 2.0, Azure Active Directory B2C and Azure API Management

Answer 2

If you wish to test your API in Azure Developer Portal using the console, Well, the consumption Tier does not fit and null/ means you don't have a domain name to access the portal. So better use one of these as Tier when creating your APIM instance: Developer, Standard or Premium. Apart from that, you will have two redirects url when you create your OAuth2.0 server (Developer portal and Developer portal deprecated), configure both of them in your registered client application.
