Variables are reusable values you can use in your API requests and scripts. Environments make it easier to change variables based on your work context, such as sending requests to a test or production server. When you switch between environments, all variables in your requests and scripts use the current environment's values. To learn more about managing environments in Postman, see [Group sets of variables in Postman using environments](/docs/sending-requests/variables/managing-environments/). ## Add environment variables To create an environment and add variables to it, do the following: 1.
