Your tests need credentials and configuration (base URLs, API keys, tokens) to run against your environment. Set these as environment variables and Checksum injects them into every API test run.

​
Open the environment variables page

There are two ways to get there:
  • From API Tests, click Secrets.
  • From Settings → Secrets.
Both open the same Environment Variables page.

​
Add variables

​
One at a time

Click Add Variable, enter a Name and Value, and save. Use the reveal toggle to check a value, and the row actions to edit or delete it later.

​
Import from a .env file

Click Add Variable → Import from .env to bring in many variables at once. You can:
  • Drop or browse for a .env file, or
  • Paste KEY=value pairs directly.
Comments (# ...) are ignored. Checksum shows a preview marking each variable as New or Overwrite before you confirm the import.

Environment variables hold secrets like API keys and tokens. Values are masked by default; only reveal them when you need to verify a value.
