        "content": "## 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**](https://docs.n8n.io/hosting/configuration/configuration-examples/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](https://ngrok.com/docs/getting-started/) ([example](https://docs.n8n.io/hosting/installation/server-setups/)) or by self-hosting with one of [n8n's recommended deployment options](https://docs.n8n.io/hosting/installation/server-setups/).

But if you're new to n8n and in a rush to test a webhook's functionality, you can use [PostBin](https://www.postb.in/) as demonstrated in this workflow to test a proof of concept fast and avoid any unnecessary time on n8n setup and configuration."
