  Praveen Alavilli commented on Providing Full Featured Payments (API) at Scale Slide 2: Not many people realize that PayPal has always been an API company. We were doing APIs for a really really long time. It all began with money transfers between PDAs and email payments, but pretty quickly we started opening up APIs to enable merchants collect payments from various ecommerce applications.

  Praveen Alavilli commented on Providing Full Featured Payments (API) at Scale Slide 4: Payments domain might sound simple – after all it’s all about moving money between two entities. But the context in which they are made, and various scenarios & use-cases that they play in is just amazing. Over years through the APIs we have built, we did enable quite a large set of payment capabilities that probably no other payment provider supports today.

  Praveen Alavilli commented on Providing Full Featured Payments (API) at Scale Slide 5: If we look back and see what kind of integration methods we have enabled – again you will see a wide range of methods. This of course could have been done in a better way establishing some consistency and using some open standards, but again as I said earlier – when we were building these, the API ecosystem did not even exist! Yeah our buttons are so web 1.0 but keep in mind no one even knew that web has versions at that point.

  Praveen Alavilli commented on Providing Full Featured Payments (API) at Scale Slide 6: So with all those APIs providing several capabilities and enabling different integration methods – you can imagine what kind of a complex env/infrastructure we have to internally deal with and of course we all know what external developers feel when they see our APIs – nothing to hide here!
