I'm an online shopper who loves efficiency and hates filling out forms, so TwoTap's solution that automates the checkout process across top e-commerce websites immediately grabbed my attention. Not only does TwoTap help automate checkout, but the TwoTap API gives developers a new way to handle referral-based e-commerce. With just a few calls to the API, developers can complete a purchase on a customer's behalf.
Dwolla has adopted the Kotlin programming language, with a focus on helping its Java clients. Specifically, the company created a new Kotlin-based SDK for its API. Dwolla maintains that Kotlin is wholly compatible with Java and, more importantly, simpler to use and maintain.
