InterFAX REST PCI Fax API Reference


The InterFAX REST PCI fax API is a commercial subscription-based service which enables the transmission of fax messages without the need to install any hardware or software. The original document to be transmitted may be of various formats, such as PDF, Microsoft Word, HTML, TXT etc. Received faxes are in TIF or PDF format.

As an extension to sending capabilities, the Interfax Fax REST API provides facilities for retrieving status information regarding fax messages sent through it.

It follows the requirements of the PCI-DSS compliance.

If you would like to use our standard REST API (the non-PCI version), please read our documentation here.
