PayPal revamps developer program with new iOS SDK, retooled APIs

PayPal(s ebay) readily admits it hasn’t been the most developer-friendly company, but the online payments giant claims it is now ready to start actively courting the developer with a bevy of new tools it is launching at SXSWi.

First off, it’s launching a new iOS software developer’s kit (SDK), which allows app makers to code PayPal’s payment processing tools directly into their apps, instead of opening up a PayPal authorization and payments page. PayPal devs can also embed credit card scanning software from, which PayPal bought last summer. While it’s starting with iOS, PayPal said it would expand to other mobile platforms “soon.”

For quick integration, PayPal has developed Javascript buttons that can be embedded into a desktop or mobile website by adding five lines of codes. The payment feature can also be programmed into a QR code, allowing retailers to trigger transactions from outside of the device. Finally, PayPal is also retooling its application programming interfaces (APIs) around more modern and open frameworks such as REST, OAuth and JSON.

Previously, PayPal’s development platform ran over parent company eBay’s X.commerce, but PayPal is taking its developer efforts independent, launching a new development website that houses its sandbox, tools, documentation and other resources in a single location.

“This is just the beginning,” PayPal CTO James Barrese wrote on the company’s blog. “We will be releasing new APIs and capabilities throughout 2013, while continuing to support our existing developer tools through this evolution. We will continue to listen to the developer community and rapidly respond to their feedback.”
