When a client sends SMS via the API, the platform can automatically send a delivery report (DLR) to a webhook URL of their choice. This lets the client's system receive real-time status updates for every message sent.
Before You Start
The API access must be enabled for the client in the admin panel. Go to Profiles → Clients, open the client's edit page, and make sure the Can Send via API feature is enabled.
Set Up DLR Sending to Webhook
Go to API → GET.
In the DLR sending to webhook block, enter the webhook URL in the Send SMS State via API field.

This is the address where delivery reports will be sent for each SMS. The URL should be provided by the client's development team.
If you want the platform to wait for a confirmation response from the webhook before marking the delivery report as sent, enable the With confirmation checkbox.
Click Save, then click Check Response to verify that the webhook is reachable and responding correctly.
Once saved, the platform will start sending DLR reports to the specified URL for every SMS sent via API.
