AADSTS500113: No reply address is registered for the application

The app registration has no redirect URI for the platform being used, so Entra ID has nowhere to send the response.

Seen on: Azure

Meaning

Each platform (Web, SPA, Mobile/desktop) has its own redirect URI list. New registrations without any redirect URI, or using the SPA flow with only Web URIs, cause this.

Common causes

  • No redirect URI configured
  • Redirect URI added under the wrong platform
  • App still using a deleted URI

⚡ Quick fix

  1. Add the redirect URI under the correct platform in Authentication
  2. Match the redirect URI used by your code exactly

Detailed fix by platform

Azure CLI

  1. az ad app update --id <app-id> --web-redirect-uris https://app.example.com/signin-oidc

How to diagnose

  1. Platforms — Authentication blade entries
  2. Code — redirect_uri sent in the request
