Send WhatsApp message

POST /message-server/whatsapp/send

Sends a WhatsApp message. The content can be:

A Meta-approved template (template)
A free-form message (body) — only within the 24h window from the user's last message

The template and body fields are mutually exclusive: one of the two is required.

Fallback: If the message cannot be delivered via WhatsApp, fallback to RCS and/or SMS can be configured.

Tracked links: For templates with tracked links, insert the shortLinkT1 placeholder in the placeholders map with the actual destination URL.

Request

Request processed. Check results.whatsapp.accepted to verify whether the message was accepted.

Note: accepted: true means the message was accepted for sending, not that it was delivered. Delivery confirmation arrives via webhook.
