Terminator

The Terminator Block will end a Flow as soon as it has edge data on all incoming edges.

You can also end a Flow branch without terminating the Flow using the Sinkhole Block.

If you have multihere we have parallel executing Subflows, the Flow won't terminate until the longest running Subflow has completed.

Send data in response

If the Flow is launched via the API (as opposed to the editor) and you want to return the data arriving at the Terminator, then you should check the Send data in response box.

If the Terminator has multiple incoming edges, each edge will be represented in the response as shown below.

{
    "data0": "OK",
    "data1": [
        {
          hubspot_id: '125005142222'
        },
        {
          hubspot_id: '125005142215'
        }
    ]
}
