# Extend
## Introduction
The Extend section in DBSync Cloud Workflow provides powerful customization capabilities to help you go beyond standard integration configurations. Use Javascript to create and apply User Defined Functions (UDFs) and other custom logics to dynamically manipulate, transform, and validate data during integration.
Extend is designed to support where default mappings and logic aren't enough to meet unique business requirements. With the ability to create and apply User Defined Functions (UDFs) and other custom logic, users can manipulate, transform, and validate data dynamically during the integration process.
These extensions handle complex operations such as formatting, conditional logic, data normalization, and dynamic routing. This section is ideal for those looking to tailor their integrations with reusable code, apply business-specific rules, and maintain consistency across multiple workflows.
