. Thank you for your interest in PHP eFax!
What are the requirements to use PHP eFax?
You need to have an eFax® Developer account. PHP eFax only works with that system. If you have an eFax email account, it will not work with our library--you will have to upgrade to the full eFax Developer system in that case.
You need to install the HTTP Request module. This module is used to send requests to the eFax® Developer server. More information can be found in our PHP eFax documentation.
A valid SSL certificate is also strongly suggested.
Can I send faxes with this system?
Yes. eFax Developer sends fax everywhere in the world.
Can I receive faxes with this system?
Yes. Receiving faxes requires adding one PHP file to your server to accept connections from eFax® Developer to your server.
Note also that the eFax® Developer connections require you to have a valid SSL certificate signed by a third party such as VeriSign, GoDaddy.com, etc.
Do I need an SSL Certificate?
In order to send faxes, an SSL certificate is not required unless you want to get the confirmation automatically (we actually strongly suggest you get a certificate no matter what.)
On the other hand, if you want to receive faxes, an SSL certificate is a requirement.
Any type of SSL certificate signed by a third party will do--you do not need a certificate that will allow you to do e-Commerce.
Can I uniquely identify each fax?
The eFax® Developer system assigns a unique identifier to each fax going out and coming in. That identifier can be used to query the eFax® Developer server and on your end it can be used to uniquely link faxes to your users.
