PayPal provides a faster, safer way to pay and get paid online, via mobile devices and in stores. With 143 million active accounts in 193 markets and 26 currencies around the world, PayPal enables global commerce, processing more than 9 million payments every day. From its initial product which enabled consumers to exchange money via PDA devices, PayPal has been enabling online merchants to accept secure payments via PayPal, helping users access money in their PayPal accounts via ATM machines and enabling consumers to pay at POS terminals in stores.

From enabling simple HTML buttons for the web, PayPal APIs evolved over the last 14 years, and enabled integrations across a variety of channels including mobile, POS, ATMs and other connected devices like televisions and gaming consoles. Through the years, PayPal’s external APIs became increasingly inconsistent, complex and difficult to use, and its internal SOA built on proprietary approaches became tightly coupled and was slowing development.

To address these issues, PayPal began developing a new API and Services Platform in 2012 basing it on principles such as API as a Product, API First and loosely coupled services. The new API Platform was initially launched in 2013 to external developers and partners, and is now being used by PayPal’s own developers to build PayPal’s new products and experiences in hours instead of weeks.

In this talk, you will learn about how PayPal’s API Platform evolved both internally and externally, the principles and patterns used, and how it is enabling the future of Money.
