Square announced the launch of the Square In-App Payments Software Development Kit (SDK), enabling developers and sellers to process payments with Square within their consumer-facing mobile apps for the first time. With just a few lines of code, developers can easily and professionally build a fully PCI compliant, secure, and elegant Square-powered payments flow in their Android or iOS apps. With this SDK, developers leave the complexity of payments to Square and focus instead on providing a delightful buyer experience. The In-App Payments SDK is available for iOS, Android, and Flutter starting in the United States, Canada, UK, Australia, and Japan. The In-App Payments SDK provides a customizable payments flow that works with the most popular payment types. The SDK includes a beautifully designed, interactive user experience that guides buyers as they enter their credit card information, preventing errors and providing a smoother checkout experience. Developers can use this default flow as-is, update certain elements, or customize the entire experience to match the look and feel of their apps. Buyers can pay with their credit or debit cards, digital wallets such as Apple Pay and Google Pay, or can choose to save their credit card information for future purchases. The SDK further establishes Square’s omnichannel payments platform, making Square the only platform with first-party products that provide an end-to-end payments experience across in-person, web, and mobile app transactions. By using one platform for payments, developers and sellers minimize the complexity, security, and compliance of managing payments across channels. For sellers that also means a single, unified system for back-office reporting and the ability to see a holistic view of their buyers’ behavior for easier customer service and loyalty. Square In-App Payments SDK was PepperHQ, which creates customized, merchant-branded mobile apps for hospitality companies looking for mobile payments, order ahead solutions, and more. In partnership with Square, Pepper provides seamless integration of ordering and payment in to a merchant's systems and operations. Pepper used the In-App Payments SDK so that their merchant customers can use the same payments provider in their mobile app that they use in-store.
