Hi there community! We're developing new platform that integrates PayPal payments. Our last development was 4-5 years ago with Express Checkout for Digital Goods. My questions is - What is preferably the best API we should use and why? I saw that there is new Brain Tree API? Should we consider it? Does it require some company registration somewhere? What it offers? Also there is the REST API.. We're selling world wide and for our new platform we want to benefit from the micro transactions. Do both APIs support micro transactions? Do we need some special setup? Thanks to everyone willing to help! Cheers, Tony
