Set Session Value

This action is only available as a session-based action.

The Set Session Value action allows storing custom metadata within a Grid Viewer session.

Each value is defined using a key-value pair:

Parameter	Description
Key	Unique identifier used to store and retrieve the value
Value	The data associated with the key

These values are stored within the current viewer session, making them accessible throughout the session workflow.

Session values can later be retrieved using the Get Session Value action.

This mechanism is useful for storing temporary state information or metadata related to a specific viewer session, such as user selections, navigation context, or device-specific flags.
