# Environment Variables {% embed url="" %} Ddosify Environment Variables Feature {% endembed %} 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.

#### Attach Environment into Tests 1. In the Ddosify App, go to the Test Suite and choose the Environment you previously created using the dropdown menu in the top-right corner of the Test Suite.

2. Utilize the `{{environmentVariableName}}` format to insert test data into one of the following locations: URL, headers, query parameters, or authentication.
