App55 is a UK-based online payment service that enables merchants, websites and mobile application developers to offer their customers secure, one-click payments for products or services via any internet-enabled device.
App55 offers a restful API for access to their payment services. Use the API to send requests to the App55 platform in order to manage users, manage cards, and perform transactions. Responses are returned in JSON or JSONP. Authentication is via API key.
Of the many APIs we published this week, eight were highlighted on the blog by our team of writers. In this post, we’ll shine a spotlight on those eight, which included the app55 API. The app55 API is a UK-based payment service provider that offers developers a simple, secure payment method. The most unique feature of the API is its PCI outsourcing, allowing for third parties to better handle the security. To learn more about the app55 API visit the app55 site as well as the app55 API blog post.
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.
