Register Mercury Webhook
POST/api/mercury/instances/:instance/webhook
Register a fresh webhook for a Mercury instance. Any webhook previously registered for this instance, and any webhook pointing at the same receiver URL, is deleted first, so this is safe to run repeatedly to repair a broken subscription.
This endpoint currently requires session authentication; Personal Access Token scope support is in progress.
Authentication: Requires Bearer token.
Mercury generates the signing secret; SKU.io stores it and uses it to verify each delivery. Returns 422 when Mercury rejects the request (for example, an expired token).

Response Headers
Unauthenticated — the bearer token is missing, revoked, expired, or malformed. Never retry automatically; fix the credential. See the Errors guide.
Forbidden — the token lacks a required scope, the endpoint is not available to API tokens, or the user behind the token lacks the permission. A human must adjust the token scopes or user permissions; do not retry.
Not found — no record with the given identifier (or the route does not exist). Verify the ID before retrying.
Unprocessable Entity
Response Headers
Rate limited — platform limit is 1,000 requests/min; individual tokens may carry lower limits. Honor the Retry-After header before retrying. See the Rate Limits guide.
