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.
When Amazon recently implemented what it calls "efficiency guidelines" in its Amazon Product Advertising API, the online retail giant took some developers by surprise. The change was meant to limit access to sites that did not send buying customers. However, a change to your code is required to ensure that you receive the correct level of access. Those that didn't make the change were subjected to the lowest limits. For some, that meant lost revenue--both to the developer and Amazon.
