PayPal provides faster and safer ways to pay and get paid online. Processing over $145 billion in total payment volume in 2012, and in 193 markets, PayPal's core business has been powered by APIs since its inception. Beginning with simple HTML buttons for the web, PayPal APIs evolved over the last 14 years, driven by business needs and technology evolution, have enabled integrations across a variety of channels including mobile, point of sale and other connected devices (e.g. televisions, game consoles).


In this talk, you will learn about how PayPal redesigned its APIs using the lessons learnt on this journey, the principles, patterns and anti-patterns in API design.
