Square today announced the launch of its in-app payments SDK that allows developers to build Square-powered payments right into their mobile apps. While Square remains best known for its offline payments solutions that grace virtually ever independent coffee shop and quirky corner store, the company has long offered APIs for taking online payments on the web and for working with its reader hardware.
Today’s launch expands the company’s reach into mobile apps, an area where it faces stiff competition from the likes of Stripe, Adyen and others. Square, however, argues that this launch puts it ahead of the competition, given that it now offers a complete online and offline payments solution.
“With the introduction of in-app mobile payments to the Square platform, developers now have a complete, omnichannel payments solution for all their payment needs,” said Square developer lead Carl Perry in today’s announcement. “From software to hardware to services, Square offers a complete payments experience all in one cohesive open platform. Even better, developers and sellers can manage all their payments across in-store, mobile and online all in one place.”
The SDK is available for Android, iOS and Flutter, Google’s toolkit for building cross-platform applications. For now, only developers in the United States, Canada, UK, Australia and Japan will be able to use it, though. The app provides a default payments flow, but developers can also customize it to match their apps and needs. Using this service, mobile app developers will be able to take payments through the usual credit and debit cards, as well as Apple Pay and Google Pay.
