Use Your Work in Postman to Generate Code for Your Apps

If you work on front-end code, you probably know how to use Postman to build, develop, and test APIs. You’re used to tweaking your parameters or payload to get your call working just the way you want it to. But you can also leverage all of that work to save yourself time and effort in another way.

Once you’ve got your API right where you want it, you can use it to  generate code snippets in your language or framework of choice, and those snippets can be copy-and-pasted from Postman into your front-end apps.

That’s right: When you build an API in Postman, you don’t have to write a lick of code!

Generate Code in Postman

Once your API call is working the way you want it to in Postman, you’re ready to generate your code snippets.

  1. On the right, under Save,  click the Code link.

  2. In the Generate code snippets dialog, select the language or framework you want to use to update the generated code.

  3. Copy and paste the code into your app. 

Customized Code Snippets  

Postman also lets you customize the way your snippets are generated. So, for example, if you’re creating Java or NodeJs snippets and your project has specific linting requirements, you can specify the number of spaces to indent.

You could also use the customization tool to break a statement into multiple lines of code. Depending on your operating system, the line-continuation character might be a \ (for OSX/Linux)  or a ^ (for Windows). Set this line-continuation character and customize the way Postman generates your code snippet.

To customize your snippets: In the Postman app, under the general settings, enable New Code Generation Mode. Then, at the top of the Generate code snippets dialog, you’ll see an additional Settings icon. Click that icon to find all of the customization settings for the language or framework that you’ve selected. The settings will vary based on your language or framework.

Code Generation in API Docs Created with Postman

Now, users of your APIs can enjoy the time-saving grace of code generation as your team. If you create web documentation for your API with Postman’s Documentation feature, developers browsing your API docs can generate code snippets right in the docs, just as they would in Postman.

To generate code snippets in API docs: Select your language of choice, customize your settings, and copy and paste into your app.

Organizations like BigCommerce and Intuit use Postman code generation for developer onboarding. This allows external developers as well as new team members to get up to speed more quickly.

Postman documentation allows the developer to generate code in multiple programming languages. This saves time and effort when using unfamiliar programming languages.
