Send WhatsApp MessageOverview

Send Your First WhatsApp Message

The Bahasha WhatsApp API lets you send WhatsApp messages programmatically.

This documentation is for sending WhatsApp messages via API. Connect your phone number and create message templates in the Bahasha Dashboard .

Workflow

  1. List phone numbers — get the id of the sending number
  2. List templates — discover template names, language codes, and required variables
  3. Send a message — POST to /v1/whatsapp/send with the phone number ID, template name, and variables
  4. (Optional) Attach media — override the template’s default header image, video, or document per send

All endpoints require an Authorization: Bearer <key> header. See the Authentication section for more details.
