The Payfirma Push Android SDK by Payfirma allows to integrate payments through API interaction. An example use case shows ACME as the invoicing application that intends to include credit card payments using the interface. Input and output variables display code associated to merchant's payment. For facilitation purposes, sample code presents a business transaction with a determined filter.
The app55 API lets online and bricks and mortar merchants in the UK take payments from customers on any device, on websites designed and controlled by the retailer. app55 joins 362 payment APIs in our directory. In addition to offering one click, being fully brandable (meaning the customer sees your site only, and is not aware of app55's role), all of the stiff PCI compliance issues that make handling these transactions so complex is outsourced through them.
