## Usage
In order to receive chargeable Braintree tokens as part of your `PaymentResponse`, you'll need to add some Braintree specific parameters to your `PaymentMethodData`.

Here's an example of a Braintree enabled Payment Method Data:

```diff
const METHOD_DATA = [{
  supportedMethods: ['apple-pay'],
  data: {
    merchantIdentifier: 'merchant.com.your-app.namespace',
    supportedNetworks: ['visa', 'mastercard', 'amex'],
    countryCode: 'US',
    currencyCode: 'USD',
+   paymentMethodTokenizationParameters: {
+     parameters: {
+       gateway: 'braintree',
+       'braintree:tokenizationKey': 'your_tokenization_key'
+     }
+   }
  }
}];
```
