Create webhook — POST /v1/provider/linear/webhook

POST /v1/provider/linear/webhook

The address Linear delivers Issue and Comment events to. An issue event is mirrored into the native todo — idempotently by identifier, so ENG-123 is one row however many times it is edited, moved or closed — and every issue and comment event is handed to the automations engine as a verified trigger, which is how an org runs an agent when an issue is assigned to it or a comment mentions it. A remove is never propagated: the native side is canonical.

It answers a benign 200 for what it does not act on — an unknown organization, other event types — so Linear does not retry-storm. A bad signature and a delivery older than a minute are 401; only a sink failure is 502.

The delivery names its Linear organization; that organization's own webhook secret — sealed at /v1/provider/linear/claim — verifies the HMAC over the raw body, so the tenant is the organization the signature proves, never a header.

The caller here is the PLATFORM, not a Hanzo tenant, so there is no bearer and no principal. The signature check IS the authentication, and it fails closed. The tenant is never read from the payload either: it is resolved from the verified platform identifier through the connection map, so an event from a workspace nobody connected does nothing. Refusals are written with their own status rather than being flattened to a 500, so a rejected signature reads as 401 and a malformed body as 400.

Request

The document declares no body for POST /v1/provider/linear/webhook. The handler is typed in cloud but its shape is not yet emitted, so the fields are not listed here — ask MCP's describe for post_provider_linear_webhook, which answers from the running route.

Response

The document declares no response body for this operation. It answers 200 on success and the platform error shape on failure — see Errors.
