About the speaker: 

Vaibhav Porwal, Engineering Manager at Chargebee 

  • He was employee no. 2 at Chargebee
  • His first objective was setting up a QA framework, followed by getting into the thick of things with core product development, and then, branching deeper into what would become a mainstay: integrating the doors through which one can access the potential of the product 
  • For 3+ years, he led the engineering efforts to integrate the right payment methods and gateways. (GoCardless,Adyen, Stripe, Paypal, Direct Debit, ApplePay to name a few) 
  • His key contributions came in the form of APIs, databases, webhook processing systems etc

About Chargebee:

  • It is processing over $2 Billion in revenue for thousands of subscription-based businesses across the world
  • Today, they support 10 different payment methods (Credit Cards, Paypal, ApplePay, Direct Debit, ACH, ACH Credit Transfer, Amazon Payments, Alipay, ApplePay, WechatPay) in 50+ countries

What will be discussed?

  • Core challenges with global payment gateways
  • How card payments are fundamentally different from DD or ApplePay. Which one to choose when
  • How to implement payment reconciliation mechanisms
  • How to implement a webhook processing system

Examples on:

  • GoCardless direct debit integration
  • Implementing a reconciliation mechanism with Paypal Express checkout. Generic design pattern allowing to extend for more gateways quickly

Why should you attend?

  • This isn’t just for fintech businesses. In fact all businesses have a fintech domain in some sense.
  • So, whether you’re a B2B or B2C product, understanding the systems that allow for digital cash registers to ring, is critical.
  • Every single integration with a payment method and a gateway has opened doors for Chargebee to new markets

Key learnings:

  • The centrality of payments in software systems

  • Regulations & bank transfer processing

Who should attend?

The attendees are expected to know the terms used in payment systems like gateway, merchant accounts, payment types, regulatories, web hooks, apis, etc

  • Product managers/owners -> to understand the technical complexities of implementing payment gateways
  • Developers -> to learn how to design a payment system and the best practices around this.
