APIs are available with the affiliate networks as well as with some programs that work directly with merchants. Of course, use of an API with an affiliate program brings with it the publisher's share of work. The publisher has the tasks of registering with the API program, obtaining needed API security credentials, and the coding to call the API; a skill that not-all content publishers are ready for. There are many API industry proponents that want to steer API evolution towards developer-free implementations and the affiliate marketing space will be a prime candidate for that kind of progress.
