# Types of Custom Action Avo Assure supports majorly two Custom Action types to fit your automation needs: 1. **Generic (not tied to UI elements)** Define actions under **@Generic** to perform broad operations like fetching file paths, altering environment variables, or handling data—capable of being used anywhere in the test. {% hint style="warning" %} **Note:** *Custom Actions for @Generic Element can be written using both, JavaScript and Python.* {% endhint %} 2. **Element-specific** * **JavaScript-driven Custom Actions** Built for dynamic interactions: you select an element from the Element Repository, then write JavaScript that manipulates or validates that selection— e.g., custom DOM logic in MS Dynamics. * **Python-based Custom Actions** Ideal for backend or environment operations such as calling os.environ.get("TEMP") to fetch runtime system details. These run outside the browser context and retrieve data based on provided input parameters. ### Input Syntax Guidelines When working with Custom Actions in Avo Assure, especially those written using Python or \ JavaScript, it is critical to understand how to correctly define and pass input values. These \ values can be **static**, **dynamic**, or **derived from previous steps**. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
