1. Sign up and add send credits
Create your GoFax account and buy send credits. API faxes and SMS use the same credits as everything else.
Fax and SMS Integration for Developers
Connect online fax and SMS to your own software with the GoFax REST API. One token sends and receives both, with webhooks for instant updates. Australian owned and ISO 27001 certified.
How do I add fax and SMS to my software?
Use the GoFax REST API. Create a GoFax account, add send credits and create an API token. Your system can then send and receive faxes and SMS in JSON over HTTPS, from any language that can make web requests. There is no extra fee for the API. It uses the same credits.

Getting started guideInstant updates with webhooks
Webhooks tell your system the moment something happens, so it does not need to keep checking. GoFax sends a webhook when a fax is sent, when a new fax arrives and when an SMS reaches its final status.
