# Overview

## What is a Catch Hook?

When we use the phrase "Catch Hook", we are referring to a mechanism designed to receive and process incoming webhook notifications or events.

Catch Hooks can be configured to perform various actions that can be categorized under to main functions:

- Email Notifications
- Update User Access

### Main Functions and Triggers

**Email Notifications** Catch Hooks can send automated emails to users based on the following triggers:

- Course Completed
- Chapter Completed
- No Sign In
- Start Date
- Expiration

These notifications allow you to communicate with users proactively, for example, emailing users who haven’t signed in recently to encourage them to resume training or congradulating them for completing a course or chapter.

**Update User Access** This function allows Catch Hooks to modify a user’s content access, typically to unlock new training based on completed prerequisites, but you can also reset a user's welcome video.

- Course Completed
- Chapter Completed

This enables automated learning paths such as: Complete Course A → Unlock Course B → Unlock Course C → Unlock Course D
