Developer Center for Health Care APIs


You need fast, secure APIs to access health care data from the nation’s largest payers. Availity is here to help. To make our APIs even better and easier to use, we’re moving to a new platform. If you’re just getting started, you can try the APIs, get a key, and register your apps on the new platform now. If you registered your key on or before August 13th, you can still get to the legacy API Key and account information – but you’ll want to get a new key right away to take advantage of the new features and avoid interruptions to your service.
