Postman Flows is a visual, low-code editor you can use to build almost any workflow you can imagine. In this tutorial, you'll create a two-block flow module that displays the text Hello, world. You'll learn how blocks and connections work and prepare yourself to build larger and more complex flows.
With flow modules, you can create reusable flow components that can be added to multiple other flow modules and actions. You can share your flow modules with teammates so they don't need to rebuild the same components.
You create flow modules in a workspace. Use workspaces to organize your API projects and collaborate with your team.
To create a new flow module, do the following:
Use the String block to define text, which you can send to another block.
To add a String block, do the following:
In the next procedure, you'll connect this block to a Display block to display your text.
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. The Display block displays incoming data, such as the String block's string value.
To connect a Display block, do the following:
From the canvas toolbar, select Run.
Congratulations! You built your first flow module and displayed Hello, world in a Display block.
