Action Message Format (AMF) is a binary format used to serialize ActionScript objects. It is used primarily to exchange data between an Adobe Flash application and a remote service, usually over the internet.

Typical usage from Adobe Flash Player, consists of an ActionScript program which:

  1. Connects to a specific "gateway" URL on a web server
  2. Accesses the service which handles AMF communication
  3. Calls a method on the service, mentioning a "callback" method
  4. Arguments passed are serialized to AMF and deserialized at the receiving end
  5. The service processes the input, and optionally returns data via AMF
  6. The callback method is invoked by the platform, and returned data is passed
