Loyalty APIs (Legacy)

Welcome to the IAG Loyalty's API Documentation Portal

You can use this site to view details about all of our live APIs.

IAG Loyalty's APIs are RESTful with standard HTTP methods and status codes. All requests should be made over SSL. All request and response bodies, including errors, are encoded in JSON. To use the APIs, all partners will need to obtain an API key by registering.

To use the APIs:

  • Partners need to register and obtain an API key.
  • Partners and members must have registered with a supported loyalty programme such as British Airways Executive Club, Aer Lingus AerClub or Vueling Club.
