# Render Template

`POST /v1/templates/render`

## Request

- Base URL: `https://api.mentium.io` (the document declares no server; this is the origin it was published from)
- URL: `https://api.mentium.io/v1/templates/render`
- Auth: HTTP bearer

Render an email template from business context.

This endpoint is intentionally decoupled from offer sending: it does not create
offers, carrier offers, conversations, or public booking tokens. Any server-only
values such as ``offer.public_booking_link`` must be passed through overrides.
