The GoCardless PHP Client Library is a simple PHP interface to the GoCardless API. The client requires PHP version 5.3. GoCardless is a service that lets users accept online payments. With the API, users can create subscriptions, pre authorization, and automated bills. In addition, the API can read existing resources and create bills under a pre-existing authorization.
Google has introduced a one-click payment experience via a new Payment Request API. The API eliminates the need for a traditional checkout experience by handling the payment experience through a simple API call. The service is not a payment method, nor does it integrate with payment processors.
