Getting paid by your customers is the ultimate goal of e-commerce. Payment takes on this challenge by providing a robust platform for processing payments, regardless of the application you need it for. The Drupal 7 version has been serving Drupal Commerce and Ubercart customers for years now, and the upcoming version for Drupal 8 brings all the improvements you have asked for, such as custom payment status handling, pluggable payment method selection and recurring payments. With six plugin types and four entity types it will be one of the most powerful modules available. This talk will give site builders an overview of how easy it is to use Payment out of the box. After that we will jump down the rabbit hole and explore the really awesome possibilities that the different plugin types have to offer. After this session you'll know how to write your own payment methods and payment types, which is all you need to build a kick-ass e-commerce platform!
