# Webhook

### Overview

The **Webhook** allows you to execute workflows remotely from external sources. Instead of triggering actions manually, or on some set precise time, you can now run workflows real-time in response to or **reaction to certain external events**.

This is ideal for automation use cases such as monitoring user cases, for real-time interactions based on certain other external triggers.

***

### What the Webhook Do

The Webhook acts as a **event-based trigger** that starts your workflow execution in reaction to any external event. Once configured, it runs independently without manual intervention.

{% hint style="info" %}
The webhook is configured so that no duplicate requests can be made within 2 seconds. This is to ensure duplicate requests are not made out in error, and to ensure any DDOS attacks.

Hence, please make sure to wait 2 seconds before making a 2nd request; else it will return a failed message.
{% endhint %}

The webhook comes some few key security capabilities:

* **None:** Quick and easy setup with an open access; perfect for the public-facing utilities. Anyone with access to the given link or by clicking the link (either from a form or button) will directly trigger the workflow.
* **Basic Auth:** A basic way to keep your things private with a user defined username and password. This is a basic 
* **JWT Token:** Enterprise grade security best suited for enterprises.

***

### Configuration Options

#### 1. Security

Choose your desired security level from any of the following options:

* **None**
* **Basic Auth (Username/Password)**
* **JWT Tokens (Enterprise grade security)**

***

#### 2. Create Webhook link

By clicking the set button, it generates a unique webhook URL link:

* This URL is very unique and specific to your given workflow only.
* You have the provision to reset it anytime you feel that the link has been compromised or exposed.

***

#### 3. Trigger

You can now go ahead and copy-paste that generated webhook URL to your destination locaiton.

Example:

* Web browser
* 3rd party applications (Zapier, Make.com, n8n etc)
* Postman

***

### Common Use Cases

* **Event monitoring**
* **Delayed smart contract execution**
* **Automated periodic fund transfers**
* **Scheduled data reads or API calls**
* **Time-based notifications or alerts**

***

### Example Workflow

**Scenario:** Run a Web3 workflow when a n8n has completed certain process.

* Webhook: `URL`
* When to Run: `n8n API call node is executed` 

Result: The Web3 workflow executes automatically every time the API node in n8n is executed.
