Build API-first apps with Postman Flows—a visual, low-code editor

You can use Postman Flows to prototype and build API-first apps in a collaborative environment. Automate tasks, integrate systems, and showcase your APIs to others on your team—or the entire world with the Postman API Network.

Postman Flows is available on Postman Free, Basic, and Professional plans, and on Enterprise plan by invitation. Each plan includes a monthly limit. You can pay for more credits. To learn more, see Manage your team's usage of Postman Flows.

Get started with Flows

With Postman Flows, you can use a visual, low-code editor to assemble building blocks on an infinite, drag-and-drop canvas. These building blocks may contain data, such as text or a date, or perform a task, such as solving a mathematical problem or sending an API request.

Use the editor and canvas to arrange your blocks to complete nearly any workflow you can imagine. Or you can use the Postman Flows Catalog to explore ready-to-use Flows. If that sounds like a lot, you can start by building a "Hello, world" Flow.

Build Flows

You build Flows with blocks and connections. You use blocks to store information or perform a task, and connections to pass information or trigger an action. When you connect two blocks, you connect one block's input to another block's output. Inputs are on the block's left side and outputs are on its right side.

Work with data in Flows

In some cases, you may want to use advanced logic to work with data. With Postman Flows, you can use the Flows Query Language (FQL) or Typescript for Flows to query and transform data and add conditional logic.

FQL is a query programming language built by Postman for Postman Flows. If you need to query and transform your data, FQL is a great option. TypeScript (a superset of JavaScript), on the other hand, is a complete programming language. If you need to work with more complex logic, TypeScript for Flows is a better option.

Learn Flows with tutorials

Tutorials are a great way to familiarize yourself with the Flows editor and canvas, and prepare to build your own API-first projects. With these tutorials, you can get started with beginner tutorials and go further with advanced tutorials. If you prefer to watch videos, you can explore the Flows video tutorials.

Build Flows with AI

Postbot is Postman's AI assistant. You can use natural language to ask Postbot to build or add to your Flows. Postbot also helps you find and fix errors.
