LoyaltyOS uses conventional HTTP response codes to indicate the success or failure of an API request. In general, codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a points transaction failed, etc.). Codes in the 5xx range indicate an error with LoyaltyOS's servers.

HTTP Status Code Summary

Error Code


200 - OK

Everything worked as expected.

400 - Bad Request

The request was unacceptable, often due to a missing required parameter.

401 - Unauthorized

No valid API key was provided.

402 - Request Failed

The parameters were valid, but the request failed.

404 - Not Found

The requested resource doesn't exist.

429 - Too Many Requests

Too many requests were made to the API too quickly. We recommend implementing an exponential backoff for your requests.
