#run(method, params = {}) ⇒ Object

Do a POST request to PayPal API. The method argument is the name of the API method you want to invoke. For instance, if you want to request a new checkout token, you may want to do something like:

response = request.run(:express_checkout)

We normalize the methods name. For a list of what’s being covered, refer to PayPal::Recurring::Request::METHODS constant.

The params hash can use normalized names. For a list, check the PayPal::Recurring::Request::ATTRIBUTES constant.
