  * @link https://developer.paypal.com/webapps/developer/docs/classic/api/merchant/SetExpressCheckout_API_Operation_NVP/
  *
  * @param array $args {
  *     @type string 'currency'              (Optional) A 3-character currency code (default is store's currency).
  *     @type string 'billing_type'          (Optional) Type of billing agreement for reference transactions. You must have permission from PayPal to use this field. This field must be set to one of the following values: MerchantInitiatedBilling - PayPal creates a billing agreement for each transaction associated with buyer. You must specify version 54.0 or higher to use this option; MerchantInitiatedBillingSingleAgreement - PayPal creates a single billing agreement for all transactions associated with buyer. Use this value unless you need per-transaction billing agreements. You must specify version 58.0 or higher to use this option.
  *     @type string 'billing_description'   (Optional) Description of goods or services associated with the billing agreement. This field is required for each recurring payment billing agreement if using MerchantInitiatedBilling as the billing type, that means you can use a different agreement for each subscription/order. PayPal recommends that the description contain a brief summary of the billing agreement terms and conditions (but this only makes sense when the billing type is MerchantInitiatedBilling, otherwise the terms will be incorrectly displayed for all agreements). For example, buyer is billed at "9.99 per month for 2 years".
  *     @type string 'maximum_amount'        (Optional) The expected maximum total amount of the complete order and future payments, including shipping cost and tax charges. If you pass the expected average transaction amount (default 25.00). PayPal uses this value to validate the buyer's funding source.
  *     @type string 'no_shipping'           (Optional) Determines where or not PayPal displays shipping address fields on the PayPal pages. For digital goods, this field is required, and you must set it to 1. It is one of the following values: 0 – PayPal displays the shipping address on the PayPal pages; 1 – PayPal does not display shipping address fields whatsoever (default); 2 – If you do not pass the shipping address, PayPal obtains it from the buyer's account profile.
  *     @type string 'page_style'            (Optional) Name of the Custom Payment Page Style for payment pages associated with this button or link. It corresponds to the HTML variable page_style for customizing payment pages. It is the same name as the Page Style Name you chose to add or edit the page style in your PayPal Account profile.
  *     @type string 'brand_name'            (Optional) A label that overrides the business name in the PayPal account on the PayPal hosted checkout pages. Default: store name.
  *     @type string 'landing_page'          (Optional) Type of PayPal page to display. It is one of the following values: 'login' – PayPal account login (default); 'Billing' – Non-PayPal account.
  *     @type string 'payment_action'        (Optional) How you want to obtain payment. If the transaction does not include a one-time purchase, this field is ignored. Default 'Sale' – This is a final sale for which you are requesting payment (default). Alternative: 'Authorization' – This payment is a basic authorization subject to settlement with PayPal Authorization and Capture. You cannot set this field to Sale in SetExpressCheckout request and then change the value to Authorization or Order in the DoExpressCheckoutPayment request. If you set the field to Authorization or Order in SetExpressCheckout, you may set the field to Sale.
  *     @type string 'return_url'            (Required) URL to which the buyer's browser is returned after choosing to pay with PayPal.
  *     @type string 'cancel_url'            (Required) URL to which the buyer is returned if the buyer does not approve the use of PayPal to pay you.
  *     @type string 'custom'                (Optional) A free-form field for up to 256 single-byte alphanumeric characters
  * }
