}Execute Workflow
Submits a workflow for asynchronous execution and returns an execution_id to poll. The request accepts either a structured payload referencing a stored workflow_id (preferred) or inline workflow JSON (legacy). By default a stored workflow runs its live version, or its draft if no version has been deployed; set environment to test to run the draft. A workflow whose reachable nodes include an unknown node type, or a connection from an output a node does not have, is refused before the run starts with 400 and an error that begins “invalid workflow”. Nodes not reachable from the trigger are ignored. Authentication accepts the x-api-key header, or an X-Webhook-Secret header matching the workflow trigger’s webhookSecret, in which case the run executes as the workflow’s owner.
