Check the delivery status of a sent message using its unique message ID — returns DELIVRD, FAILED, or PENDING.

Submit a new DLT template for approval or fetch the list of your already-approved template IDs.
Register a webhook URL to automatically receive delivery receipts and inbound SMS replies in real-time.
Every API call returns a clear JSON response — store these status codes to power retries and reporting dashboards.
