# Extend with Code

**Purpose**: Expand the app's capabilities and scale for production.

**How It Works**: Utilize custom code widgets, integrate external REST APIs, or connect with other tools and services to create a robust, scalable application. Buzzy AI can help you generate code widgets, or you might call on a developer at this point - see the [Buzzy Marketplace](https://marketplace.buzzy.buzz/) for options!

**Key Features**: Scalability, third-party integrations, advanced security, and compliance features.

**Outcome**: A full-stack, production-ready application hosted on a secure Kubernetes infrastructure.

{% hint style="info" %}
For more complicated integration and extensions, it helps to have some dev skills (or access to someone who does)! If you find this daunting or are getting stuck, you might want to call on an expert via the [Buzzy Marketplace](https://marketplace.buzzy.buzz/).

## Custom code widgets

Custom code widgets allow you to embed custom code in your Buzzy app. Use **embedded markup** for static html or SVG, a **sandboxed iframe** if you have custom code (eg JavaScript), or a **trusted iframe** to embed media such as Youtube or Vimeo.

There are three different ways of using code widgets in your app when it comes to having them present or process app data:

1. Using data from the current row
2. Using data from a child table in a custom format
3. Using data from another table or tables

## Rest API

The Buzzy REST APIs (which are a type of web API) involve requests and responses. You make a request to a resource stored on the server, and the server responds with the requested information. The protocol used to transport the data is HTTP(S). “REST” stands for Representational State Transfer.

## Datatable Rules

Datatables provide the ability to fire rules on events (eg update, click , new row created) that allow Actions to be called.

## A real live app example - with code snippets!

Beginning life as an idea turned into a prompt turned into a simple MVP via Buzzy AI, which was extended with an AI-powered recommendations engine, the [AI Strategy Plan App](https://app.aistrategyplan.com/) is a great example of the Buzzy **Kickstart/Enhance/Extend process**.
