PayZang, payment processing provider, has introduced a new payment API. The API allows merchants to integrate payment options with third party applications and platforms. PayZang hopes to attract new customers with the API because integration will speed up online shopping and bill pay experiences.
SumUp, a mobile payments rising star, recently announced an API that allows third party apps to accept credit card and cash payments without leaving the app. Prior to the API, SumUp users and customers were required to use the SumUp app in isolation from the merchant app to utilize the slick mobile payments platform.
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.
