SMS Delivery Receipts via HTTP
Delivery receipts let you know whether a message has been delivered. We forward them to you by making an HTTP request to a URL of your choice.
To enable delivery receipts on your account
- Login to Clockwork and choose “Delivery Receipts” under the “Sending” menu option
- Enter your server URL
- Set the Type to either HTTP Get or Form POST
- Save your settings
It takes around 30 minutes for delivery receipt changes to apply to your API account. We make HTTP calls on port 80 and HTTPS on port 443, so you shouldn’t need to open any more ports.
