Common Mistakes

  • File must be served over HTTPS (not HTTP)
  • No redirects allowed when serving the file
  • Apple AASA file must NOT have a .json extension
  • Android requires SHA-256 fingerprints for both debug and release keystores
  • Apple App ID format is Team ID + "." + Bundle ID (e.g., ABCDE12345.com.example.app)
  • For Android, ensure autoVerify="true" is set in your intent filter
  • Both files must return HTTP 200 (not 404 or any other status code)
  • The .well-known directory must be at the root of your domain
