# Errors

RedirHub 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 or was invalid). Codes in the `5xx` range indicate an error with our servers.

Generally speaking, API errors are broken into the following categories:

* **Request Validation Errors** - A request was made with invalid parameters. This can be because of a missing parameter, an invalid parameter, or a parameter that is not allowed.
* **Rate Limit Error** - The request was made too many times in a given amount of time.
* **Billing/Subscription Errors(fixed code:** 482**)** - The action need higher grade subscription or the corresponding account does not have an active subscription.
* **Permissions Errors** - You do not have sufficient permissions to invoke the request API endpoint, and/or access the requested resource.

Some `4xx` errors will include a list of errors with additional attributes. This may be useful to programatically handle the error or display an error message in your own UI.

```javascript
{
  "message": "Invalid Request",
  "errors": [
    {
      "resource": "rule",
      "param": "forward_params",
      "code": "invalid_option",
      "message": "Must be true or false"
    }
  ]
}
```
