The Problem We Were Actually Solving
My goal was to build a seamless ebook purchase experience for users in various regions, where PayPal, Stripe, Gumroad, and Payhip were either blocked or highly restricted. I knew that our app's unique value proposition - providing data-driven insights to its users - could be compromised if I had to resort to traditional (and inflexible) payment gateways. The problem, however, was that our existing infrastructure was tied to these platforms, making it a high-risk, high-reward move to explore alternatives.
What We Tried First (And Why It Failed)
Initially, I attempted to use a third-party ebook sales platform like E-junkie, which promised to integrate seamlessly with popular ecommerce solutions. Unfortunately, their API offered limited control over the checkout process, and I couldn't quite get the customizations we needed without extensive custom development. We also experimented with a headless ecommerce solution like Shopify Plus, but their APIs and payment gateways still required us to expose sensitive financial data to the web, which went against our security best practices.
The Architecture Decision
After reviewing our options and weighing the pros and cons, we decided to go with an in-house solution using an embedded payment processor called Mollie. This allowed us to handle ebook purchases directly within our app, without exposing our users to 3rd-party payment gateways. The architecture decision came with its own set of trade-offs, such as increased complexity and responsibility for managing payment processing ourselves, but it ultimately gave us the flexibility to design the checkout experience that best suited our app's unique requirements.
What The Numbers Said After
After implementing the new payment processing system, we saw a significant drop in abandoned cart rates (from 35% to 12%) and an increase in average order value by 20%. This was a testament to the tailored checkout experience we had designed for our users. Plus, the integration was smooth enough to meet our stringent data freshness SLAs (ensuring that the ebook inventory levels and purchase history were up-to-date within 5 minutes of the transaction).
What I Would Do Differently
Looking back, I would have done even more due diligence on the specific regulations and restrictions imposed by traditional payment gateways. It's crucial to understand the nuances of payment processing in different regions to avoid the ecommerce trap altogether. I would also invest more in ensuring the in-house payment processing system is highly available, scalable, and maintainable, perhaps using distributed transactional frameworks like Apache Kafka or Rediscala.
In conclusion, navigating platform restrictions for data-driven apps can be a daunting task. However, by taking a closer look at the problem we're trying to solve and exploring unconventional architectures, we can unlock new opportunities for growth and innovation while avoiding the limitations imposed by traditional platforms.
