# Retrieve available countries

Use the **getAvailableCountries** method to get the list of available countries for the current merchant. If the language parameter is provided, all the returned countries will be translated into that language.

## Request parameters <a href="#request-parameters" id="request-parameters"></a>

<table><thead><tr><th width="119.0667724609375">Parameter</th><th>Type / Description</th></tr></thead><tbody><tr><td><code>sessionId</code></td><td><p><strong>Required (string)</strong></p><p>Session identifier, the output of the <strong>Login</strong> method. Include <code>sessionId</code> into all your requests. 2Checkout throws an exception if the values are incorrect. The <code>sessionId</code> expires in 10 minutes.</p></td></tr><tr><td><code>language</code></td><td><p><strong>Optional (string)</strong></p><p>The ISO language code (two-letter code). If the language parameter is empty, the default language will be English.</p></td></tr></tbody></table>

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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.2checkout.com/json-rpc-api-reference/json-rpc-api-6.0/api-requests/retrieve-available-countries.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.
