The FusionCMS API 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, etc.), and codes in the 5xx range indicate an error at the server level.


All error responses will be returned within an error array of your request. Error responses will include the following information:

  • Status Code
  • Message

Here's an example of a returned 404 response:

    "error": [
        "message": "Category not found.",
        "status_code": 404
