# Response Codes and Error handling

## Response Codes <a href="#response-codes" id="response-codes"></a>

Our API services typically use following HTTP response codes and their meaning. Any deviations or additional details are described separately with each service reference.

<table><thead><tr><th width="152">CODE</th><th>Standard Meaning</th><th>Description</th></tr></thead><tbody><tr><td>200</td><td>OK</td><td>Typically response to a successful GET request.</td></tr><tr><td>202</td><td>Accepted</td><td>Typically response to a successful POST request.</td></tr><tr><td>204</td><td>No Content</td><td>Service responded successfully, but there is no content - typically empty GET /messages service response.</td></tr><tr><td>403</td><td>Forbidden</td><td>Authorization or authentication failure. Typical cases: certificate is not valid or expired, the service is not enabled for the customer or Client-Code and Client-Country headers are not valid for the <a data-mention href="/pages/dGB6nyMWtFDzDyra2uDe">/pages/dGB6nyMWtFDzDyra2uDe</a></td></tr><tr><td>404</td><td>Not Found</td><td>Resource is not found. Typically a specific message is already deleted or does not exist.</td></tr><tr><td><a data-footnote-ref href="#user-content-fn-1">429</a></td><td>Too many requests</td><td><a data-footnote-ref href="#user-content-fn-1">Too many requests in a given amount of time.</a></td></tr><tr><td>500</td><td>Internal Server Error</td><td>Technical error. Typically unplanned service interruption.</td></tr><tr><td>503</td><td>Service Unavailable</td><td>Technical error. Can also be used during planned maintenance</td></tr></tbody></table>

## Error Handling <a href="#error-handling" id="error-handling"></a>

In case of any errors our default structure of error details is following.

Service specific details of error codes and messages can be found at each service description.

<table><thead><tr><th width="97">INDEX</th><th width="95">MULT.</th><th width="157">ELEMENT</th><th width="149">XML TAG</th><th>DESCRIPTION</th></tr></thead><tbody><tr><td>1.0</td><td>[1..1]</td><td>Errors</td><td>&#x3C;Errors></td><td></td></tr><tr><td>1.1</td><td>[1..n]</td><td>+Error</td><td>&#x3C;Error></td><td></td></tr><tr><td>1.2</td><td>[1..1]</td><td>++ErrorCode</td><td>&#x3C;ErrorCode></td><td>For example, see list of Account Statement Request Error Codes.</td></tr><tr><td>1.3</td><td>[1..1]</td><td>++Description</td><td>&#x3C;Description></td><td>Description text.</td></tr><tr><td>1.4</td><td>[0..1]</td><td>++Field</td><td>&#x3C;Field></td><td>Reference to faulty field.</td></tr></tbody></table>

## 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, and the optional `goal` query parameter:

```
GET https://docs.lhv.com/home/connect/fundamentals/response-codes-and-error-handling.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
