Authentication

The Newtrition API uses API keys for authentication. Create, manage, and learn more about API keys in our dashboard .

Danger

Remember that your API key is a secret! Do not share it with others or expose it in any client-side code (browsers, apps). API keys should be securely loaded from an environment variable or key management service on the server.

API keys should be provided via HTTP Bearer authentication.

Authorization: Bearer NEWTRITION_HUB_API_KEY

Errors

If authentication fails, the API will return a 401 Unauthorized status code with the following error response:

{
  "error": {
    "message": "Unauthorized",
    "details": "Invalid or expired token"
  }
}

This error occurs when:

• The API key is missing from the request
• The API key is invalid or malformed
• The API key has expired
• The API key has been revoked or deleted

Make sure to check that your API key is correctly formatted and hasn’t expired. If you continue to experience issues, generate a new API key from the dashboard.
