Error handling
Lune returns errors with an HTTP status code, a Lune-specificerror_code, and an error message. Additionally, errors include a CF-Ray header, which can be reported to Lune for troubleshooting.The following example shows a sample error object:The current error response also includes an
errors array. This array is deprecated. Please refer only to the error JSON object for guidance.Handling errors in Lune
See below for some tips on handling errors when working with the Lune API:- HTTP 4XX errors: Use the
error.messageto determine how to correct the request. - HTTP 5XX errors: Retry the request. If the error persists, please contact us.
- If the issue is a timeout or connection error, retries will not create duplicate orders or calculations. Lune employs idempotency keys to prevent unintended duplicates.
- HTTP 404 errors: The requested resource does not exist. Verify your request and endpoint parameters.
- HTTP 429 errors: You have exceeded the rate limit. Wait before retrying.
Error codes
Lune provides variouserror_code values to simplify error handling. These are typically paired with 4XX HTTP status codes (for example, 400, 409, 422).The most common error is validation_error (paired with a HTTP status code of 400), returned when a request does not meet validation requirements. The response message specifies which properties are invalid.For endpoint-specific errors, refer to the API reference for that endpoint.
