# Update Global Variable **Introduction** This step is designed to update the value of an existing global variable. **Configuration** * **Variable**: Select the global variable you wish to update. The variable must have been previously defined and accessible as a global variable. This is a required field. * **Value**: Input the new value for the global variable. This value must conform to the variable's predefined schema. The schema ensures the consistency and validity of the data within the size limits established for global variables. **Usage** Essential for modifying data stored in global variables, which can be useful for maintaining state, updating configurations, or tracking data across multiple automations or over time. --- # 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.
