# Avantra Extensibility APIs

Welcome to the Avantra API documentation center. Avantra is a powerful and very extensible platform that provides our customers opportunities to build their own monitoring checks, powerful automation scripts, scripted notification channels and control Avantra through our APIs.

This section of the documentation site is written to provide technical details on how these APIs work and how to get started building on Avantra.

## JavaScript Extensibility

Avantra allows for our customers to build extensions throughout the product. We provide scripting functionality with JavaScript to build custom logic to create custom checks that monitor the information that’s important to you, to create complex custom automations that can be executed on your entire landscape to save you time and to create a bespoke notification channel to integrate with the outside world when we detect an issue.
