Call the API

Use the number's API token in your code or automation tool.

Built for developers

Plain JSON over HTTPS with one bearer token per number.

Each number has its own API token, and you can replace it at any time.
Webhook calls carry a signature header you check with your secret.
Numbers are fully separated: one number's token never reaches another's data.

POST /v1/messages
{
  "recipient": "14155550132",
  "type": "poll",
  "question": "Which day suits you?",
  "options": ["Monday", "Tuesday", "Wednesday"]
}

{
  "id": "evt_01HXAB…",
  "type": "message.received",
  "occurred_at": "2026-10-15T11:32:04Z",
  "chat_jid": "14155550132@s.whatsapp.net",
