# Scripts

Accessed through clicking Development > "**Scripts"** link on the left side panel of the application.

Scripts are a way of defining custom logic and data transformations that can be executed as part of the integration process. Scripts can be used to automate complex or custom tasks that can not be performed using Mappings, standard data transformation capabilities and Map Chains.
