The Request class concatinates the Request::ROOT_URL constant with the API_PATH constant of the extending class, which results in a double slash in the URL.
saferpay.com seems to ignore this issue, but it may cause problems in case they will not accept such URLs in the future
Example
Request::ROOT_URL = 'https://www.saferpay.com/api/'
AliasAssertInsertRequest::API_PATH = '/Payment/v1/Alias/AssertInsert'
Request::getURL() will combine this to
https://www.saferpay.com/api//Payment/v1/Alias/AssertInsert
