Authenticate the Test User { "error_type": "OAuthException", "code": 400, "error_message": "Invalid platform app" }

Question

I'm trying to recover the access token via the Instagram Basic Display API but when trying to authenticate the test user I get this error:

{
    "error_type": "OAuthException",
    "code": 400,
    "error_message": "Invalid platform app"
}

I expect to see the app authorization screen

When setting up an Instagram app, you should use the platform-specific App ID and not the generic one set up on Facebook.

In your Facebook app Dashboard go to Products > Instagram > Basic Display and should see the Instagram App ID.

Use that in your authorization URL and it should work.
