Root

Root task is a very specific task which isn't deletable. This is where all your workflows will start execution. This is why you cannot connect anything to it (no Blue input port).

Main tab​

tab

Total running instances
Lets you define a maximum of running instances for this workflow.

Max running instances by node
Lets you define a maximum of running instances for each node.

Trigger Error port
Allows you to define if the home error port will be triggered on the first child task error, or at the end of the workflow execution.

Player context
Allows you to define a context for the Workflow Player execution. Context should be a valid JSON object.

Log tab​

tab

Lets you define how loggers should behave. Beware that the more logs are sent the slower your workflow will execute.

Web API tab​

Lets you define how the workflow can be triggered via a web-service.

To trigger this workflow:

  • Select the node you want to use for execution.
  • Select which workflow version to execute.
  • Copy the "Start workflow URL".
  • By posting the URL you will get the following answer.
"result": true,
"response": {  
  "status": "https://ait-c7/workflow_template/webapi/eyJpbnN0YW5jZV9pZCI6IDg2LCAiY21k9",
  "pause": "https://ait-c7/workflow_template/webapi/eyJpbnN0YW5jZV9pZCI6IDg2",
