Running an existing workflow

Is it possible to run an existing workflow by workflowId? I’m looking through the /run endpoint in Server.ts and it seems like the data that is POSTed to this endpoint includes runData, startNodes, & destinationNode which aren’t saved in IWorkflowDb, or anywhere in mongo it seems.

What you can find in Server.ts is only for starting the workflow in development mode. If you want to run a workflow regularly you can simply create a Webhook-Node to start it with it.

Apart from that, it is also possible to start a workflow by ID as described here:
