Overview

Use these endpoints to queue OTP messages and raw WhatsApp payloads for delivery.
These endpoints queue messages for async processing. A successful 200 OK response means the request was accepted for processing, not that the message has already been delivered.

​
Available endpoints

Send OTP message

Send one OTP through Modawer’s official WhatsApp account.

Send OTP from your WhatsApp account

Send OTPs from a connected WhatsApp Business account.

Send raw message

Queue a raw WhatsApp template payload.

​
Shared behavior

  • Authentication is handled with the X-API-KEY header.
  • Route-level JWT authentication is not required.
  • When a dev token is used, messages are routed to the app’s linked Telegram chats instead of the provided recipient.
  • Send OTP Message uses Modawer’s official WhatsApp account and is the fastest way to start sending OTPs.
  • To send OTPs from a custom sender ID, use Send OTP from Your WhatsApp Account.
  • OTP templates require a verified WhatsApp Business Account (WABA) when using your own sender.
  • Utility and marketing templates can be sent from a linked WhatsApp account without completing business verification.

​
Request conventions

  • JSON property names are camelCase.
  • OTP messages use the built-in otp_code_1 authentication template.
  • Raw messages wrap the WhatsApp payload in a top-level payload object.
