Telzio API v3
This is the newest version of Telzio's free API, and also the same as our apps are using.
Version 3 of the Telzio API is different from prior versions as all calls are now processed in lieu of a user on your account. To authentication, you must first log in with a user's credentials which will return a bearer token that can be used for other calls.
We are currently working on implementing the documentation for the API on this page. Until then, you can find it at https://api.telzio.com/v3
