# useAccessToken

Hook to read the Embedded Wallets access token for the current session. Send the access token to your backend to authorize requests on behalf of the signed-in user.

### Import

```tsx
import { useAccessToken } from '@web3auth/react-native-sdk'

```

### Usage

```tsx
import { useAccessToken } from '@web3auth/react-native-sdk'
import { Button } from 'react-native'

function CallBackendButton() {
  const { getAccessToken, loading } = useAccessToken()

  const callBackend = async () => {
    const accessToken = await getAccessToken()
    if (!accessToken) return

    await fetch('https://<YOUR_BACKEND>/api/me', {
      headers: { Authorization: `Bearer ${accessToken}` },
    })
  }

  return <Button title="Call backend" disabled={loading} onPress={callBackend} />
}

```

### Return type

```tsx
import { type IUseAccessToken } from '@web3auth/react-native-sdk'

```

#### `getAccessToken`

`() => Promise<string | null>`

Reads the access token from secure storage and updates `accessToken`. Resolves with `null` and sets `error` if the user isn't signed in or the session has no access token. Sessions created by passing an `idToken` to `connectTo` don't have an access token.

#### `accessToken`

`string | null`

Most recent access token, or `null`.

#### `token`

`string | null`

Deprecated alias of `accessToken`.

#### `loading`

`boolean`

`true` while `getAccessToken` runs.

#### `error`

`Web3authRNError | null`

Error from the most recent `getAccessToken` call, or `null`.
