Iterating through data is a common task in many workflows, particularly when dealing with lists of items or collections. This will guide you on how to set up a loop within a workflow to process each item in a dataset.

Preparation

Before setting up the loop, ensure you have:

  • A dataset to iterate over, such as a list of user records, products, or any other collection.
  • A clear understanding of the processing or actions needed for each item in the dataset.

Setting Up the Loop

  1. Identify the Loop Location: Determine where in the workflow the iteration should occur.
  2. Configure the Loop Node: Add a 'Loop' node in your workflow where you need to process each item in your dataset.

Example Scenario: Processing User Data

Imagine you have a list of users and you need to update each user's status based on certain criteria.

Dataset Structure

Assume each user record in your dataset looks like this:

{
  "userId": "user123",
  "lastLogin": "2023-03-01",
  "accountType": "standard"
}

Iteration Logic

The goal is to iterate through each user and perform specific updates.

Implementing the Loop

  • Add Loop Node: Place a 'Loop' node at the appropriate point in your workflow.
  • Configure Data Source: Set the 'Property to loop over' to point to your dataset.

Processing Each Item

Within the loop, add nodes or logic to process each item. For example, you might:

  • Check if the lastLogin date meets certain conditions.
  • Update the accountType based on user activity.

Testing the Loop

  • Input Test Data: Provide a sample dataset to test the loop.
  • Run the Workflow: Execute the workflow and observe how each item is processed.

Analyzing Results

  • Check Records: Ensure each user record is processed as expected.
  • Workflow Accuracy: Confirm the workflow behaves correctly for the entire dataset.

Best Practices

  • Handle Edge Cases: Ensure your loop handles edge cases and unusual data entries.
  • Regular Testing: Continuously test and review the loop, especially after making changes to the workflow.

Note: Efficient iteration through data is vital for workflows that handle collections of items. Properly setting up and testing loops ensures your workflow processes each item correctly and efficiently.
