Set the parameter
whendelivered while calling POST /sms to
https://yourapp.io/elks/dlrs (or wherever your webhook code is). We'll make
an HTTP POST (application/x-www-form-urlencoded) request to this URL when the state of the SMS changes. This
happens when we receive confirmation from the carriers that the message was
either delivered or failed.
You may use Basic Auth by "https://username:email@example.com" url format. You may also include any extra information as query parameters like "https://yourserver.com/dlr?exmplekey=examplevalue", for example if you have your own SMS id or need to add an auth-key.
|id||The unique id of the message in our systems.|
|status||Either ”delivered” or ”failed”.|
|delivered||The delivery time in UTC. Only included if
Your webhook code must respond with a HTTP status in the range 200-204. If not, the API will consider the request failed and keep trying for up to 24 hours. The response body is ignored.
