The developer guides show you how to use the public APIs, developer tools, and other developer features of the Frosmo Platform. These allow you to go beyond the Frosmo Control Panel when developing your Frosmo-enabled site, and to create your own client applications for interacting with the Frosmo Platform.

APIs for interacting with the Frosmo Platform:
- Graniitti API provides access to the data in the Frosmo back end. You can use the API to retrieve, create, update, and delete data for your company.
- Product API allows you to retrieve product data from the Frosmo back end.
- Recommendations API allows you to retrieve recommendation data from the Frosmo back end.
Data tracking solutions for your site:
- Custom event tracking extends the basic tracking functionality of the Frosmo Platform by allowing you to track modifications beyond clicks, displays, and true displays.
- Frosmo data layer is a global JavaScript array that allows you to send data from a web page to the Frosmo back end. Use the data layer to collect product and visitor data by tracking conversions and transactions, custom actions, and products.
Tools for developing in the Frosmo Platform:
- FProxy is a desktop application and a web proxy that allows you to develop and test modification content locally on your computer, outside the Frosmo Control Panel.
- Frosmo Debugger is a web application that allows you to preview and debug modifications on your site during development. The Frosmo Debugger is an advanced version of the Preview Tool.
