Webhooks

Delivery status webhooks

Delivery status webhook payload

{
  "event": "sms.delivered",
  "messageId": "sms_7c3f21",
  "to": "+9198XXXXXXXX",
  "status": "delivered",
  "route": "transactional",
  "timestamp": "2026-08-13T10:15:00Z"

Delivery Status Webhook

Fires when a message is sent, delivered, or fails- with a timestamp and reason.

Secure Delivery

Webhooks are tied to your API key and account, so only your registered endpoint receives events.

Rate Limits & Integration Options

Built to scale with your account

How throughput limits work, and the two ways to connect depending on your sending volume.

Rate Limits

Rate limits scale with your account tier rather than a fixed cap for every account- contact your account manager for the specific limits on your plan so you can design your integration accordingly.

REST API or SMPP

Use the REST API directly for most integrations, or connect via SMPP for high-throughput enterprise sending. Your onboarding contact can help you pick the right option for your volume.

Getting Started

3 steps to start sending

Get your API credentials

Submit your DLT registration documents during onboarding and receive your API key- typically same-day to 2 business days.

Test in a sandbox

Ask your onboarding contact about sandbox/test-mode access so you can validate your integration before sending live traffic.

Go live

Switch to your live API key, point your webhook URL at your production endpoint, and start sending.

Get your Bulk SMS API credentials

Submit your DLT documents, get provisioned, and start sending- Get Click Media's integration team helps you go from signup to your first API call.
