Set default payment method

If the user has chosen the specific payment/payout method in your app's interface, you can pass this information in the Request when starting the widget: see the paymentMethod and payoutMethod fields.

If a payment/payout method is supplied, the Buy/Sell form in the widget opens with this method as the default. Users have the flexibility to change the method if needed.

If no payment/payout method is provided, Credit Card is set as the default.
