# Publish Template

`POST https://api.inboxjot.com/v1/templates/{template_id}/publish`

Makes the draft the version that API and automation sends use. Returns 409 when the draft matches the published version. Needs a Full key. A key limited to one domain answers 403. Send an optional `Idempotency-Key` header to retry safely. See Idempotency.
