Create blocks in Postman Flows

All blocks have an input port, an output port, or both. Input ports are on the left side of a block, and output ports are on the right. You can find an explanation and example for every block here.

There are several ways to add a new block:

• Right-click anywhere in the flow.
• Select the + Block button on the toolbar.
• Drag a connection from the output port of another block.

Any of these actions will open up the block list, which you can select from and that block will be added to the flow. You can also copy and paste blocks into your flow.

When you open a new flow, the first block you'll see is the Start block.

The Start block has a single output. When you select the Run button, this block sends information through a connection to the next block, causing it to run.

When you create a new flow, before you add any blocks, the Start block has colored suggestions for things you can do:

• Send a request - Creates a Send Request block.
• Add blocks - Opens the blocks list.
• Explore Catalog - Opens the Flows Catalog where you can discover and load prebuilt Flows.

Copy and paste blocks

You can copy and paste blocks in flows using your system's standard keyboard shortcuts. The pasted blocks preserve the copied blocks' configurations. If you copy and paste connected blocks, they keep their connections. You can also copy and paste annotations and groups.

To copy and paste blocks in a flow, do the following:

1. Select a block. For multiple blocks, hold ⌘ or Ctrl while selecting the blocks.

2. Select ⌘+C or Ctrl+C to copy the block.

3. Select ⌘+V or Ctrl+V to paste the block.

Tip: You can copy blocks from one flow and paste them in a different flow.
