You can pass variables between Workflows. This is useful if you want to use a previously created variable within the scope of a single Workflow. For example:

  • You want to collect user information in one Workflow, then validate it in a sub-Workflow.
  • You have a Workflow that stores items in a virtual shopping cart, and you want to process payment for those items in a sub-Workflow.
  • You have some condition in one Workflow, and you want a sub-Workflow to behave differently based on that condition.

To pass variables between Workflows:

1

Setup your input variable

  1. In your sub-Workflow (the one you want to pass the variable to), create a new Workflow variable.

You can pass any kind of variable from your parent Workflow, but your sub-Workflow needs to treat it as a Workflow variable.

  1. Select the Entry Node of your sub-Workflow, then select the variable you just created:

This tells the parent Workflow that your sub-Workflow is expecting some input.

2

Pass the variable to the sub-Workflow

In your parent Workflow, select the Card that transitions to the sub-Workflow. It should display the input variable you just created:

You can manually enter a value to pass to the sub-Workflow, or use a previously created variable from your parent Workflow.

Now, whatever value you pass from your parent Workflow will be available in your sub-Workflow as a Workflow variable.
