SMS Gateway - Cellcast

The Cellcast SMS Gateway delivers SMS messages internationally.

Incoming Messages/Replies

You can get incoming messages/replies to your Cellcast number into the fmSMS file in 2 ways:

• Manually Download Incoming Messages
• Use Webhooks to have Cellcast 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 Cellcast as they are received.

Manual Download Incoming Messages

You can download incoming messages manually via the Account Details screen. To check and download any new messages click the Get Incoming Messages button:

Any incoming messages to your Cellcast number that have not been previously downloaded will then be downloaded. You could also setup a FileMaker Server script schedule to have this run on a scheduled basis (e.g.every hour) to save you from having to manually download/check for new messages.

Cellcast Webhooks Setup

To receive incoming SMS messages to your Cellcast 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 you can enter this into your Cellcast account settings as follows:

1. login to your Cellcast account via their website
2. click on API Connect in the side navigation then Inbound sms settings
3. enter the URL in the Input Webhook URL field
4. click Update
