Python Fax - Send a Binary File Using SendFax

Download the Python samples fax API zip file.
Download the Modified OSA files.

This sample demonstrates how to submit a binary file to the fax Web service. This is done using SendFax with Python.

The SendFax method also indicates whether the submission succeeded. The return value of a successful submission is the transaction ID (positive number) of the fax in the system. Other return values indicate a failure (for more details, see Web Service Return Codes).

As explained above, the following Python fax snippet sends a binary fax from Python and indicates whether the submission succeeded:
