# Errors

## HTTP status code summary <a href="#http-status-code-summary" id="http-status-code-summary"></a>

Customer 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 create failed, etc.). C Codes in the 5xx range indicate an error with customer servers (these are rare).

Some 4xx errors that could be handled programmatically (e.g., a create customer fail) include an error code that briefly explains the error reported.

| Error Code              | Meaning                                                                                          |
| ----------------------- | ------------------------------------------------------------------------------------------------ |
| 200 - OK                | Everything worked as expected.                                                                   |
| 400 - Bad Request       | The request was unacceptable, often due to missing a required parameter.                         |
| 401 - Unauthorized      | No valid API key provided.                                                                       |
| 402 - Request Failed    | The parameters were valid but the request failed.                                                |
| 404 - Not Found         | The requested resource doesn’t exist.                                                            |
| 409 - Conflict          | The request conflicts with another request (perhaps due to using the same idempotent key).       |
| 429 - Too Many Requests | Too many requests hit the API too quickly. We recommend an exponential backoff of your requests. |
| 500, 502, 503, 504      | Server ErrorsSomething went wrong on customer’s end. (These are rare.)                           |
