Replies are defined as messages that are returned on an outgoing message, within a certain period. This period can vary; it is at least 5 days. To receive replies to SMS messages, you are required to send out the original message with a SenderID that is reply-enabled. Messages to that number need to be delivered at CM.com's messaging platform and the number must have been configured to process reply messages.

CM.com has a set of shared numbers available that are free to use to receive your replies on. The downside of using one of these numbers, is that traffic from other customers using the same number could interfere with your traffic, making replies unreliable. For reliant and confidential communication, we advise you to obtain a dedicated phone number. Contact support for more information about choosing and acquiring a suitable SenderID.

This feature is free of charge, and can be configured via the CM.com Gateway app. (For the reception of inbound messages, costs may apply, depending on contract and country of destination.) Click the 'Reply settings' button in the top right to set up your incoming messages.
Enable replies for your account using the checkmark at the top and at the bottom, add your URL to send your message to. The default 'Json' format is the preferred choice, as the other formats (Xml and Get) are subject to change and might be deprecated in the near future.
