Fax Service Provider Application Programming Interface

The Fax Service Provider application programming interface (API) allows you to integrate a fax device into the fax service.

The first part of this overview describes the components you need to support the Fax Service Provider API, and the functionality the API supplies. It also includes a brief discussion about virtual fax devices, and the error control that the fax service provides. Finally, it outlines fax service provider registration requirements and describes programming guidelines you should use for developing a fax service provider dynamic-link library (DLL).

The second section of this overview includes a code sample that demonstrates how to create and post fax service provider status changes to the fax service. The sample also describes how to transmit a fax using a virtual fax device.

Before you read this overview you should be familiar with the Telephony Application Programming Interface (TAPI) Programmer's Reference and the Microsoft Telephony Service Provider (TSPI) Programmer's Reference.
