Fax SMTP Developer Reference
This section provides a complete reference for developers wishing to use our fax service to send faxes automatically via SMTP.
The InterFAX fax SMTP service enables initiation of fax transmissions using SMTP, from email-enabled environments, without the need to install any hardware or software. Developers can use our fax SMTP service to send plain text messages and messages with attachments of various formats, such as HTML, Microsoft Word, PDF etc.
After initiating a fax transmission, status information regarding individual faxes sent can be obtained by a variety of means: by a return confirmation email, by querying the service through the InterFAX Web Service or by viewing the outbound fax queue through web-based user administration screens.
