# Webhook

### What is a Webhook?

A **webhook** is a mechanism that enables one system (the sender) to automatically send real-time data to another system (the receiver) when a specific event occurs. Instead of the receiver repeatedly asking (polling) for updates, the sender “pushes” the data to a specified **URL endpoint**.

### Overview

* **Flexible Event Processor:**\
  **EdgeTag webhook** can process any incoming event/data and forward it to either an external system or directly into the EdgeTag platform.
* **Custom JavaScript Logic:**\
  The webhook is written in plain JavaScript, allowing developers to fully customize how the input data is handled.

### Capabilities

* **Forward Data to External Servers**
  * Accepts incoming payloads and sends them to external APIs or endpoints.
  * Useful for integrations with third-party tools or internal services.
* **Format & Transform Data Before Forwarding**
  * Modify, enrich, or sanitize incoming payloads before sending them out.
  * Ensures compatibility with external systems that expect a specific structure.
* **Send Lead Events to EdgeTag**
  * Capture lead generation events and pass them into the EdgeTag system for tracking and automation.
* **Send Custom Events from CRMs to EdgeTag**
  * Connect with any CRM (HubSpot, Salesforce, Zoho, etc.) and forward custom events (e.g., deal updates, contact changes).
* **Create a Lead in HubSpot**
  * Automatically push incoming lead data into HubSpot CRM, enabling instant contact creation and workflow triggers.
* **Create a Lead in Salesforce**
  * Seamlessly integrate with Salesforce by creating new leads from incoming webhook data.
  * Helps align sales teams by automatically updating records with fresh leads.
