# Using the Wallet Module in Wallet API Core Client

The Wallet Module allows you to interact with the user's wallet. This includes retrieving the user's ID, fetching wallet information, and listing the capabilities of the wallet.

## Wallet Module Overview

Access the Wallet module via `walletApiClient.wallet`.

### Methods:

#### 1. Get User ID

Retrieve the user ID of the connected wallet.

```javascript
walletApiClient.wallet.userId(): Promise<string>
```

- **Returns**: A promise that resolves with the user ID as a string.

[**Required permission**:](https://developers.ledger.com/docs/ledger-live/discover/guides/wallet-api/appendix/manifest#permissions)
`wallet.userId`

##### Example:

```javascript
async function getUserId(walletApiClient) {
  try {
    const userId = await walletApiClient.wallet.userId();
    console.log("User ID:", userId);
  } catch (error) {
    console.error("Error retrieving user ID:", error);
  }
}
```

#### 2. Get Wallet Info

Retrieve information about the connected wallet.

```javascript
walletApiClient.wallet.info(): Promise<WalletInfo["result"]>
```

**Returns**: A promise that resolves with an object containing information about the connected wallet.

[**Required permission**:](https://developers.ledger.com/docs/ledger-live/discover/guides/wallet-api/appendix/manifest#permissions)
`wallet.info`

##### Example:

```javascript
async function getWalletInfo(walletApiClient) {
  try {
    const walletInfo = await walletApiClient.wallet.info();
    console.log("Wallet Info:", walletInfo);
  } catch (error) {
    console.error("Error retrieving wallet info:", error);
  }
}
```

#### 3. List Wallet Capabilities

List the method IDs that are implemented by the wallet.

```javascript
walletApiClient.wallet.capabilities(): Promise<string[]>
```

- **Returns**: A promise that resolves with an array of strings representing the method IDs.

[**Required permission**:](https://developers.ledger.com/docs/ledger-live/discover/guides/wallet-api/appendix/manifest#permissions)
`wallet.capabilities`

##### Example:

```javascript
async function listWalletCapabilities(walletApiClient) {
  try {
    const capabilities = await walletApiClient.wallet.capabilities();
    console.log("Wallet Capabilities:", capabilities);
  } catch (error) {
    console.error("Error listing wallet capabilities:", error);
  }
}
```

## Handling Errors

Make sure to handle errors gracefully and provide appropriate feedback to the user. Additionally, always remember to disconnect the `WindowMessageTransport` when you're done interacting with the  API to free up resources.
