Frequently asked questions

What is Postman Flows?

Postman Flows is a visual tool for building API workflows. You can connect APIs, services, and data in a drag-and-drop interface—without writing code. It’s built for developers and technical teams who want flexibility and control over how APIs interact.

Zapier is great for automating popular SaaS tools. Postman Flows is API-first—it gives you complete control over request structure, data transformations, and logic. You can use it to orchestrate internal APIs, chain service calls, and go beyond the limitations of most no-code tools.

Yes. Because Flows are built on top of Postman’s core platform, you can connect to internal APIs, services behind a firewall, or staging environments—just like you would with any Postman request. It’s ideal for platform teams and service orchestration.

No coding required—but if you’re comfortable with APIs and how requests are structured, you’ll feel right at home. Flows lets you visually define logic, pass data between steps, and build useful workflows without writing scripts.

You can trigger Flows manually or on a schedule using Postman Monitors. Programmatic triggers like webhooks or Postman’s public API aren’t supported yet, but they’re on the roadmap.

You can run Flows interactively in your browser. Use test environments to simulate different conditions, inspect step-by-step output, and refine your logic before going live.
