Programmable Fax REST API
We have made the difficult decision to disable Programmable Fax for all accounts on December 17, 2021. For new and inactive accounts, access to Programmable Fax is disabled effective immediately. We recognize the challenges this decision might cause and have provided detailed migration plans to prevent disruptions.
For Japan customers, please refer to this migration plan. For all other customers, please refer to this migration plan. Learn more.
The Programmable Fax API allows you to send faxes, view historical faxes and media, and manage fax records in your account.
API Base URL
All URLs in the reference documentation use the following base URL:
https://fax.twilio.com/v1
Authentication
HTTP Basic Authentication is used for authentication. Pass your Account SID as the username and Auth Token as the password (find them in the console).
If you are instead using Twilio API Keys, then use the API Key SID as the username, with API Key Secret as the password.
Resources
The Fax resource is the main fax resource.
Each Fax instance resource has a single subresource, the FaxMedia resource.
Helper libraries
Our helper libraries for C#, Java, Node.js, PHP, Python, and Ruby take care of the base URL and authentication for you. For the quickest path to development, use one of the helper libraries.
Getting started
Refer to our quickstart guide for a step by step introduction to Fax and an overview of commonly used features.
