# Field Service Developer Guide

Field Service is a powerful, highly customizable toolbox of features that you can use to set up and manage a multiplatform, mobile service operation. This guide offers reference information and code examples to help you understand the structure of Field Service features and customize them with code.

This guide includes:

-   Object diagrams that illustrate the relationships between field service data objects
-   Reference information for field service objects in the REST, Metadata, and Tooling APIs
-   Apex reference information for the Field Service managed package
-   Apex code examples that you can use to complete common field service tasks

If you’re new to field service, we recommend checking out [Get on the Road with Field Service](https://trailhead.salesforce.com/en/trails/field_service) in Trailhead. Then, find curated links to documentation, blogs, Trailhead modules, and other resources through the [Field Service learning map (English only)](https://help.salesforce.com/s/articleView?id=service.fs_landing.htm&type=5)
