POST/api/public/v1/messages

Send template

Send an approved WhatsApp text template — works outside the 24-hour reply window.

Only plain text templates are supported — a template with body text and optional {{1}}, {{2}}... placeholders. Templates with an image/video/document header or buttons aren't supported by this endpoint yet — use the dashboard campaign builder for those.

Body parameters

Field	Type	Required	Description
to	string	Required	Recipient number, e.g. `919876543210`.
type	string	Required	Must be `template`.
template.name	string	Required	Exact approved template name, from Settings → WhatsApp templates.
template.language	string	optional	Language code, e.g. `en`. Defaults to `en`.
template.bodyParams	string[]	optional	Values for the body's `{{1}}`, `{{2}}`... placeholders, in order.

The template must already be approved by Meta. Unlike a plain text message, templates can be sent even outside the 24-hour customer-service window.
