Developer platform
A messaging API you'll actually enjoy
Predictable REST routes, signed webhooks, and clear errors. Send your first message in minutes and build from there.
Quick start
Send a message
Authenticate with a bearer token and POST to the messages endpoint. That's it.
curl -X POST https://api.innomessage.com/v1/messages \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d '{
"channel": "whatsapp",
"to": "+601234567890",
"body": "Your order has shipped!"
}'
Response
Clear, predictable JSON
Every response uses consistent shapes and HTTP status codes.
{
"id": "msg_1a2b3c",
"status": "queued",
"channel": "whatsapp",
"to": "+601234567890",
"created_at": "2026-06-28T09:12:00Z"
} Endpoints
