How this works
Authentication Methods for NDC APIs
NDC APIs use three primary authentication methods. HTTP Signature is the IATA standard — each request is signed with a private key, and the server verifies using your public key. Some airlines prefer OAuth2 Client Credentials for simplicity, while others use a basic API Key header. Fill in your credentials above to generate ready-to-use headers and curl commands.
