SMS Gateway - CM.com
The CM.com SMS Gateway delivers SMS messages internationally.
Incoming Messages/Replies
You can get incoming messages/replies to your CM.com number into the fmSMS file via the use of Webhooks to have CM.com push these automatically to fmSMS. Using Webhooks is the preferred method as it saves you from having to poll/check for any new messages - with Webhooks new messages are forward to fmSMS automatically by CM.com as they are received.
CM.com Webhooks Setup
To receive incoming SMS messages to your CM.com number, including replies to previously sent messages, you will need to use the supplied dedicatedNumberReply.php webhook file to act as the webhook receiver. See our Webhooks guide for what you need to do host the dedicatedNumberReply.php file on your chosen web server. Once you have the publicly accessible URL for this file follow the instructions setting up Webhooks on the CM.com website here.
