System Variable

Each process has a system variable, this is a data model that contains the medatada of the process and instance.

Each process has a system variable that serves as a data model containing the metadata of the process and its instance. This system variable plays a crucial role in the workflow by providing essential information and context about the process.

The system variable includes, but is not limited to, the following metadata attributes:

• Process ID

  : A unique identifier for the process.

• Instance ID

  : A unique identifier for the instance of the process.

• Process Name

  : The name assigned to the process.

• Workspace ID

  : A unique identifier for the workspace.

This variable can be utilized in two primary ways:

1. As an Input
   • The system variable can be used as an input to other processes or activities within a workflow. By referencing the metadata contained within this variable, subsequent processes can make informed decisions, ensuring that they have the context needed to operate correctly.
   • Example: A process may check the status of a previous instance before proceeding, or it may use the variables passed from the initial process to perform specific actions.

As a Custom Response

• The system variable can be returned as a custom response, providing detailed metadata about the process and its instance to external systems or users.
• Example: When a process completes, it can return the system variable to an API endpoint, giving external systems all the necessary metadata about the process instance.
