Similar to Postman, the Ddosify Platform offers an Environment Variables feature that allows you to store constants in variables for convenient use within your test scenarios.

#### Environment Variable Creation

1. Navigate to the Environments listing page within the Ddosify App, and find the 'New' button situated at the top-left corner of the page.

2. Assign a unique name to the new environment, which will be used to link the environment to a test. Next, create your name-value pairs. The values can be of various types, such as Number, String, or Array.
