Add code runner blocks to your notebook

You can add JavaScript code snippets and reference their output elsewhere in your notebook to create an interactive experience. For example, you can add a code runner block that generates a random number and use that number in a request block that accepts one. You can also import external libraries.

Add a code runner block

To add a code runner block, do the following:

1. Open your notebook or create a new one.
2. Place your cursor where you want to add the code runner block. Then, type a forward slash ("/"). Postman displays a block menu.
3. Choose Code Runner Block.
4. Name your code runner block.
5. Write your code.
6. Click Run.

Postman runs the code and returns the result.

Reference your code runner block

You can reference your code runner block by name. For example, if you name your code runner block "randomNumber", you can reference its output in a request block with the syntax {{randomNumber}}. Or you can reference it in another code runner block with the syntax $randomNumber.

To reference your code runner block, do the following:

1. Open your notebook or create a new one.

2. Get your code runner block's name.

3. Reference your code runner block:

   • To reference your code runner block in an input or request block, use the syntax {{codeRunnerBlockName}}.
   • To reference your code runner block in another code runner block, use the syntax $codeRunnerBlockName.
