What it does

## How to Test a Short-Lived Webhook in n8n WITHOUT Changing WEBHOOK_URL Typically in n8n, in order to test a webhook, you first need to go through the process of changing the [WEBHOOK_URL]({{ $env.WEBHOOK_URL }} environment variable to an address that is accessible to the service you want to test. Time permitting, that can be done with [ngrok]({{ $env.WEBHOOK_URL }} ([example]({{ $env.WEBHOOK_URL }} or by self-hosting with one of [n8n's recommended deployment options]({{ $env.WEBHOOK_URL }} But if you're new to n8n and in a rush to test a webhook's functionality, you can use [PostBin]({{ $env.WEBHOOK_URL }} as demonstrated in this workflow to test a proof of concept fast and avoid any unnecessary time on n8n setup and configuration.
