How to create an environment in Postman

In Postman, an environment envelops variables meant to be reused in API requests. These variables store environment-specific information that will be automatically included wherever these variables are referenced. This turns the API requests flexible, reduces the probability of errors, and increases efficiency.

An environment is simply a collection of variables stored as key-value pairs. The key represents the variable name. The following example illustrates the concept of environments:

Whenever we switch between these environments, the variable {{base_url}} 's value will change and be automatically reflected throughout the API requests, including this variable.

To foster a formal development life cycle, setting up different API environments in Postman is always better. Such segregation of environments will allow us to build custom requests based on the variables defined in these environments and easily switch between them without modifying our requests.

Environments can be exported as JSON files, imported, shared, duplicated, and removed.

Let's examine the environment's configuration in the Postman web version.
