API Testing Organizations

These are the organizations I come across in my research who are doing interesting things in the API space. They could be companies, institutions, government agencies, or any other type of organizational entity. My goal is to aggregate so I can stay in tune with what they are up to and how it impacts the API space.

REST Hooks itself is not a specification, it is a collection of patterns that treat webhooks like subscriptions. These subscriptions are manipulated via a REST API just like any other resource.

Webscripts respond to HTTP requests, making them easy to call from web and mobile apps. Webscripts have all the features you need, like password hashing and persistent storage, plus the full programmability of Lua.

Our built-in request logging makes them equally easy to debug on-the-fly. Webscripts can also be activated on a schedule, providing a simple way to build monitoring or other automation.

If you think there is an organization I should have listed here feel free to tweet it at me, or submit as a Github issue. Even though I do this full time, I'm still a one person show, and I miss quite a bit, and depend on my network to help me know what is going on.
