PayPal Launches Next Generation Developer Tools and Support for Mobile Payments Technology

Mobile SDK – Everyone knows that mobile is changing the way consumers shop
and pay, and no one more than developers who must have a mobile presence to
compete in today’s environment. We’re launching a mobile SDK so that
developers can deliver great experiences for their customers by reducing
friction when it comes to payments. Customers never leave the developer’s
app experience to pay and they have more choice in the way they want to pay
– simply click a PayPal button or scan a credit card using our
card.iotechnology. We’re making it available for iOS developers first,
but we’ll
expand to other platforms soon.

JavaScript PayPal Buttons – Developers can now integrate PayPal in seconds
by simply copying and pasting five lines of code into their website,
shopping cart or a QR code. We’re making it easy to accept payments on a
website, whether it’s a mobile device, tablet, or PC.

New REST APIs – In addition to our existing APIs, U.S. developers will now
have access to new APIs built on modern, standards-based technologies such
as REST, OAuth, and JSON.  We are beta-launching these modernized versions
of our most popular APIs –payments processing and immediate settlement – to
make it easier and faster for developers to integrate PayPal into their
experiences.
