Authentication
Authenticate with the dedicated Bearer API key safely.
Every request must include the dedicated key in the Authorization header:
Authorization: Bearer YOUR_API_KEY
Query-string keys are not accepted. A dashboard session Cookie cannot replace this key, and this key cannot access existing /bi/* routes.
Key handling
- Keep the key in a secret manager or protected environment variable.
- Never commit it to source control, logs, screenshots, or support messages.
- Do not enable Remember on this device in the Playground on a shared computer. That option stores the key in this documentation origin’s
localStorageuntil it is cleared. - Ask your Mellow contact to rotate the key if it may have been exposed.
