You can use the Foreach control step to set a sequence of steps to apply to each input data item. The output is an array of execution results for all steps in the sequence. Read more about the workflow state during the Foreach step.

  1. When creating a new workflow or editing an existing one, in the management console, under Create workflow / Edit workflow, select Constructor.

  2. From the Control steps section on the left side of the screen, drag the Foreach element to the relevant workflow location in the constructor window.

    You can drag and drop steps into areas marked by the dotted line in the workflow schema, such as Add a step, etc.

  4. At the right of the window, on the Settings tab.

    2. In the Number of input data elements processed concurrently field, set the number of input data items the specified sequence of steps will be performed on simultaneously.
  5. Optionally, navigate to the Input tab and set a jq template to filter the workflow state fed into the step.

  6. Optionally, navigate to the Output tab and set a jq template to filter the step outputs added into the workflow state.

  7. To add a new step to the sequence, drag it to the area marked by the dotted line under Integration steps or Control steps.
