Importers

The collections you save and share with Postman are all open source and can be shared, exported, published, and used as a unit of currency within any application or system, further extending the reach of the platform. To enable users of various tools to quickly get started, we've introduced modules that convert various API formats (OpenAPI / RAML / GraphQL) to Postman collections.

Postman Collection SDK + Runtime

The core of Postman is powered by Runtime that helps to execute requests, scripts, and tests in the Postman app. The Collection SDK allows you to create, manage, and automate how collections are defined and put to work across a platform without depending on the application. These two modules are closely associated.
