Workflow development

The Webhook node works a bit differently from other core nodes. n8n recommends following these processes for building, testing, and using your Webhook node in production.

n8n generates two Webhook URLs for each Webhook node: a Test URL and a Production URL.

Build and test workflows

While building or testing a workflow, use the Test webhook URL.

Using a test webhook ensures that you can view the incoming data in the editor UI, which is useful for debugging. Select Listen for test event to register the webhook before sending the data to the test webhook. The test webhook stays active for 120 seconds.

When using the Webhook node on localhost on a self-hosted n8n instance, run n8n in tunnel mode:

• npm with tunnel
• Docker with tunnel

Production workflows

When your workflow is ready, switch to using the Production webhook URL. You can then publish your workflow, and n8n runs it automatically when an external service calls the webhook URL.

When working with a Production webhook, ensure that you have saved and published the workflow. Data flowing through the webhook isn't visible in the editor UI with the production webhook.

Refer to Create a workflow for more information on publishing workflows.
