ManualTrigger Automate

For platform n8n, this workflow automates the execution of multiple sub-workflows in parallel, efficiently managing tasks through webhooks and conditional logic. It ensures all tasks are completed before proceeding, enhancing productivity and reducing manual oversight. With 18 integrated nodes, it streamlines complex processes, making it ideal for handling batch operations and asynchronous tasks.

Target Audience

Target Audience


- Developers: Those looking to automate complex workflows with webhook integrations.
- Project Managers: Individuals managing multiple tasks that require synchronization and tracking.
- Data Engineers: Professionals needing to process batches of data with asynchronous operations.
- Business Analysts: Users who need to visualize the workflow for reporting and analysis purposes.

Problem Solved

Problem Solved


This workflow addresses the challenge of managing multiple asynchronous tasks that need to report back to a central workflow. It ensures that:
- All sub-tasks are executed in parallel, improving efficiency.
- The parent workflow waits for all sub-tasks to complete before proceeding, ensuring data integrity.
- Users can easily manage callback responses and track which tasks have finished, reducing the chance of race conditions.

Workflow Steps

Workflow Steps


1. Manual Trigger: The workflow starts when the ‘Test workflow’ button is clicked.
2. Simulate Multi-Item: Generates multiple items (simulating requests) for parallel processing.
3. Loop Over Items: Initializes a batch processing loop for the simulated items.
4. Initialize finishedSet: Sets up an array to track finished items.
5. Start Sub-Workflow via Webhook: Each item triggers a sub-workflow via a webhook, sending necessary data.
6. Respond to Webhook: Acknowledges receipt of the webhook and prepares for the next step.
7. Webhook Callback Wait: Waits for callbacks from the sub-workflows.
8. Update finishedSet: Updates the list of finished items based on the webhook response.
9. If All Finished: Checks if all items have been processed; if so, it continues the workflow.
10. Acknowledge Finished: Sends an acknowledgment back to the sub-workflow.
11. Continue Workflow (noop): Placeholder for further actions once all tasks are completed.

Customization Guide

Customization Guide


- Modify Sub-Workflow: Users can edit the sub-workflow logic by replacing the webhook URL in the ‘Start Sub-Workflow via Webhook’ node.
- Adjust Parallel Processing: Change the number of items generated in the ‘Simulate Multi-Item for Parallel Processing’ node to suit specific needs.
- Webhook Configuration: Update the webhook URL and parameters to match the target API or service.
- Error Handling: Implement additional error handling in the ‘Call Resume on Parent Workflow’ node to cater to specific scenarios or retry logic.
- Documentation and Notes: Use sticky notes to add clarifications or instructions for other team members reviewing the workflow.
