IMPORTANT

In order to make Zapier correctly interworking with your PBX a valid SSL Certificates is requested and must be installed on your PBXact/FreePBX.

If you’re using a self-signed certificate, it’s likely you’ll receive an SSL Certificate Failure error. Zapier currently only supports SSL certificates which are issued by public certificate authorities.

A free SSL certificate can be obtained from https://letsencrypt.org. Let’s Encrypt is a free, automated, and open certificate authority provided by the non-profit Internet Security Research Group (ISRG).
