Templates
Register and send reviewed templates outside the customer window.
Use POST /v1/templates to register a template and
submit it for review. Review is asynchronous and may take an hour or longer for
a first submission. Use GET /v1/templates to read the
current status and accepted parameter shape.
Only an approved template can be sent. Approval is not permanent: a template
may later be paused for quality and become approved again. Read the registry
rather than caching approval forever.
For WhatsApp’s template categories, review rules, and lifecycle, see the WhatsApp Business Platform message template documentation. Linq’s template endpoints are the authority for the request and response shapes you use with this API.
A template send is validated against the registry before acceptance. A missing
or non-approved template, wrong language, or mismatched parameter set returns
422 template_not_sendable. Linq never substitutes a different template.
