*** title: Postman Flows scenarios and test data updated: 2025-02-12T00:00:00.000Z topictype: tutorial slug: docs/postman-flows/tutorials/video/work-with-scenarios max-toc-depth: 2 ---------------- With scenarios in Postman Flows, you can add multiple sets of inputs to your **Start** block, which you can then use as parameters for your API. This means that scenarios enable you to define values for multiple inputs simultaneously depending on your current task, whether you're testing a new flow you're building or running a flow regularly. Scenarios are especially convenient when you're testing flows that require specific but different data.
