# Errors

ilert uses HTTP response codes to indicate success or failure of an API request. Codes in the 2xx range indicate success, codes in the 4xx range indicate a client error (e.g. a missing required parameter) and codes in the 5xx range indicate an error with ilert's servers. In case of an error, the response body contains the following information:

| Attribute | Description                               |
| --------- | ----------------------------------------- |
| status    | the corresponsing HTTP status code        |
| message   | a human readable description of the error |
| code      | error code, used to identify error type   |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ilert.com/developer-docs/rest-api/api-reference/introduction/errors.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
