Overview

This node acts as a webhook trigger for UNC task callbacks. It listens for POST requests at a specified path and validates incoming requests using a JWT authentication token. Upon receiving a valid request, it processes the task status and either resolves or rejects a cached task promise accordingly. This node is useful for workflows that need to handle asynchronous task completion notifications securely via webhooks.

Use Case Examples

1. A workflow that triggers when an external system completes a task and sends a callback with the task status.
2. A system that requires secure verification of incoming webhook requests using JWT tokens before processing task results.

Output

JSON

• webhookResponse - Response message sent back to the webhook caller, indicating the result of processing the callback

Dependencies

• Requires a JWT authentication credential to validate incoming webhook requests.

Troubleshooting

• If the JWT token is missing or invalid, the node responds with a 403 status and an authentication challenge, preventing further processing.
• If the task ID from the query parameters does not match any cached task, the webhook will not resolve or reject any task promise, potentially causing the workflow to wait indefinitely.
