This article explored methods for importing and exporting environment variables in Postman. Environment variables are crucial for adjusting API configurations in different development, testing, and production environments.

In Postman, start by creating an environment. Click the "eye" icon in the top-right corner, select "Manage Environments," and then click "Add" to create a new environment. Fill in the environment's name and corresponding variables, such as {{base_url}} for storing the API's base address.
