X-Snowflake-Request-ID
400Bad Request. The request payload is invalid or malformed. This happens if the application didn't send the correct request payload. The response body may include the error code and message indicating the actual cause. The application must reconstruct the request body for retry.
401Unauthorized. The request is not authorized. This happens if the attached access token is invalid or missing. The response body may include the error code and message indicating the actual cause, e.g., expired, invalid token. The application must obtain a new access token for retry.
403Forbidden. The request is forbidden. This can also happen if the request is made even if the API is not enabled.
404Not Found. The request endpoint is not valid. This happens if the API endpoint does not exist, or if the API is not enabled.
405Method Not Allowed. The request method doesn't match the supported API. This happens, for example, if the application calls the API with GET method but the endpoint accepts only POST.
408Request Timeout. This indicates that the request from the client timed out and was not completed by the server.
409Conflict. The requested operation could not be performed due to a conflicting state that could not be resolved. This usually happens when a CREATE request was performed when there is a pre-existing resource with the same name, and also without one of the options orReplace/ifNotExists.
429Limit Exceeded. The number of requests hit the rate limit. The application must slow down the frequency of hitting the API endpoints.
500Internal Server Error. The server hit an unrecoverable system error. The response body may include the error code and message for further guidance. The application owner may need to reach out the customer support.
503Service Unavailable. The request was not processed due to server side timeouts. The application may retry with backoff. The jittered backoff is recommended.
504Gateway Timeout. The request was not processed due to server side timeouts. The application may retry with backoff. The jittered backoff is recommended.
