About This Workflow
Overview
This workflow template showcases how to use the n8n Wait node to manage asynchronous processes. It illustrates a primary workflow that initiates an independent process and then waits for its completion. The independent process can be triggered separately and then resume the primary workflow execution. This is useful for scenarios where an external service or a separate n8n workflow needs to perform some tasks and then signal back to the main workflow to continue.
Key Features
- Uses the
Waitnode to pause workflow execution. - Demonstrates initiating an independent asynchronous process using
HTTP Request. - Shows how an external process can resume the primary workflow execution via a webhook or other trigger.
- Allows for data transfer between the primary and secondary workflow executions.
- Provides clear guidance on how to structure and use separate workflow instances for independent processes.
How To Use
- Primary Workflow Setup:
- The workflow starts with a trigger (e.g.,
Manual Trigger). - A
Setnode (Set Primary Execution Context) defines context specific to the primary execution, including aresumeUrl. - An
HTTP Requestnode (HTTP Request - Initiate Independent Process) sends thisresumeUrlto an external process (simulated by another workflow). - The
Waitnode is configured to wait for a callback using theresumeUrl.
- The workflow starts with a trigger (e.g.,
- Independent Process Setup (Separate Workflow):
- This separate workflow would be triggered by the
HTTP Requestfrom the primary workflow (e.g., using aWebhooknode). - It performs its independent tasks.
- It then makes an
HTTP Requestback to theresumeUrlprovided by the primary workflow, often including data from its execution.
- This separate workflow would be triggered by the
- Resumption and Data Merging:
- The
Waitnode in the primary workflow receives the callback. - A
Setnode (This Node Can Access Primary and Secondary) can then access data from both the primary and the resumed secondary execution.
- The
- Customization:
- Replace the placeholder URLs and environment variables with your actual API endpoints.
- Adapt the
Setnodes to pass and receive the specific data required for your use case. - The trigger for the independent process can be any node that supports input, not just a webhook.
