What's Happening:

You're seeing a 403 Forbidden error when trying to activate your license.

403 Forbidden OAuth Error

Troubleshooting Tips:

  1. Check Your Redirect URL’s:
    • Make sure the redirect_uri you include in your request is exactly the same as the OAuth Redirect URL you set up in your AppSumo Partner Portal (opens new window). Both URLs must match perfectly for OAuth to be successful.
  2. OAuth Code Usage
    • One-Time Use: The OAuth code can only be used once and will expire after it's been used, either successful or through error.
    • New Code Issuance: A new code will be generated each time you authorize through OAuth.
    • Re-attempt Activation: To get a new code, simply re-attempt the license activation process.
  3. Re-validate Your OAuth Keys
