Atlas DocumentationChangelog
New features, improvements and fixes to the Atlas API and dashboard.
June 2026
API key mode must match your account
Atlas now rejects requests where the API key's mode doesn't match your account's mode:
- a test key on an account in live mode, or
- a live key on an account in test mode.
The API returns 401 with a message telling you which key to use.
What you need to do
Use test keys while your account is in test mode, and switch to live keys when it goes live. See the authentication guide.
