Overview

GitHub is a web-based hosting service for version control using Git. This is used to store the source code for a project and track the complete history of all the changes to that code. It allows user to collaborate on a project more effectively by providing tools for managing possible conflicting changes from multiple users.

Webhooks allow you to build or set up GitHub Apps which subscribe to certain events on github.com. When one of those events is triggered, a HTTP POST payload is sent to the webhook's configured URL. Webhooks can be configured on an organization or a specific repository.
