Can variables be passed into a subflow in ServiceNow Flow Designer?

In ServiceNow Flow Designer, it is indeed possible to pass variables as inputs into a subflow. This functionality allows for greater flexibility and reusability of workflows. When creating a subflow, you can define input variables, which are essentially the parameters that the subflow can accept. These input variables can receive data from the parent flow when the subflow is called, enabling the subflow to perform tasks based on the specific information provided by the parent flow.

By passing variables to a subflow, you can maintain context and share information seamlessly, allowing for dynamic flow execution. This design pattern supports the modular approach in workflow automation, where common tasks can be encapsulated in subflows and reused across various parent flows without the need for duplication of logic.

Utilizing subflows in this manner enhances maintainability and scalability, as you can adapt or modify the subflow independently of its callers, provided the input variable definitions remain consistent. This capability is a key feature of the Flow Designer, enabling developers to create more efficient and organized workflows.
