Update Template
Rename/re-describe a template. Content is versioned separately — see POST …/versions. Owner can edit own; org admin/owner can edit any org template.
Authorizations
Enter your MeshAPI key (rsk_...) or, for the admin-keys endpoints, a dashboard session token — sent as Authorization: Bearer <token>.
Headers
Dated version of the API contract to pin this request to. Omit it and the request is served under 2026-08 — the oldest supported version, so an existing integration is never moved by a release. A malformed or unsupported value is rejected with 400 invalid_api_version rather than falling back silently. The version actually served is echoed as X-Mesh-Version on every response, including errors.
2026-08, 2026-09 Path Parameters
Body
Metadata goes straight onto the template row. The five content fields are deprecated (MESH-503) — see DECISIONS.md — but still create+publish a version under the hood, matching this PATCH's original behavior.
