This document describes the various endpoints that Telavox exposes as the Open API. These endpoints are primarily intended for 3rd party systems that need to integrate with Telavox Flow. The reader of this documentation should be familiar with common concepts in Flow (the end-user application) and related technologies before attempting to implement a client that utilizes these services.

Changes and additions to our API will be announced on this page. Telavox reserves the right to block usage, in our sole discretion, to our API for anyone who misuses it.

Accessing our API

The Telavox Open API is located at All API methods' paths are relative to this url.

Authentication and sessions

All Open API requests uses Bearer authentication with JSON Web Tokens. The tokens are unique to each user and managed in Flow - Settings - My Account - Username and password. A faulty token will be responded with a 401 Unauthorized resopnse.


One must keep in mind when designing and adapting systems integrating with Open API that any and all data and configuration may be changed from another source. Thus it’s recommended to not store a replica of the data fetched unless it’s very frequently read and it’s accuracy isn’t critical, and when updating information in Flow it’s recommended that the information is first refreshed to make sure no modification has been made from another source since the information was first retrieved.

Character encoding and request methods

The content type and encoding of each API method is specified in the Content-Type response header. Most of the responses are JSON formatted, and all are UTF-8 encoded.

The character encoding used in request URLs is not well defined, meaning that non US-ASCII characters might present a problem and not be portable. We highly recommend specifying an appropriate Content-Type header in every request.

To explore our API in a browser, one can use the excellent Chrome add-on Postman. It can monitor XmlHttpRequests sent by the browser and by analysing these one can get a better understanding of how the API works.
