Many technical talks like to tell you the best practices to help you learn a topic. However, instead we'll approach this topic using some humor, sarcasm, and real world examples to demonstrate the worst way to do things. You'll learn why these practices are a problem especially for consumers of payment APIs so you can spot anti-patterns whether you are building your own API or choosing a partner that has an API you need to consume.
