Twilio's Proxy API is currently available as a Public Beta product. Some features are not yet implemented and others may be changed before the product is declared as Generally Available.

Public Beta products are not covered by a Twilio SLA(link takes you to an external page).

All URLs in the reference documentation use the following base URL:


All requests to the Proxy REST API are served over HTTPS. Unencrypted HTTP is not supported.

HTTP requests to the REST API are protected with HTTP Basic Authentication like other Twilio REST APIs. To learn more about how Twilio handles authentication, please refer to our security documentation.

To authenticate, you will need your Account SID and Auth Token from the Twilio Console(link takes you to an external page):

Twilio Account Summary section of the console.

You will use your Twilio Account SID as the username and your Auth Token as the password for HTTP Basic authentication.

If you use one of our helper libraries for C#(link takes you to an external page), Java(link takes you to an external page), Node.js(link takes you to an external page), PHP(link takes you to an external page), Python(link takes you to an external page), or Ruby(link takes you to an external page); you needn't worry about the URL for the API or how to do HTTP Basic authentication. The helper libraries take care of it for you.
