# HTTP status codes The Dashdoc API uses standard HTTP status codes to indicate the success or failure of an API request. Here is a list of commonly returned status codes: | Status Code | Name | Description | | ----------- | ---------------------- | ------------------------------------ | | `200` | OK | Request fulfilled | | `201` | Created | New resource created | | `204` | No Content | Resource deleted | | `400` | Bad Request | Request not understood | | `401` | Unauthorized | Invalid API Token | | `403` | Forbidden | Request not allowed | | `404` | Not Found | Resource unavailable | | `410` | Gone | Old resource permanently unavailable | | `415` | Unsupported Media Type | Feature is not enabled | | `500` | Internal Server Error | Contact us! | | `502` | Bad Gateway | Contact us! | | `503` | Service Unavailable | Scheduled maintenance | --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://developer.dashdoc.com/docs/get-started/core-api-concepts/http-status-codes.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
