The Problem We Were Actually Solving
We initially thought our problem was finding a payment gateway that worked everywhere. We tried to integrate various alternatives like Alipay, WePay, and MIGS, but it was a never-ending game of catch-up with multiple APIs, currencies, and requirements. It was like trying to solve a puzzle with constantly shifting pieces. Our users were getting frustrated, and our support tickets were piling up.
What We Tried First (And Why It Failed)
We took a deep breath and decided to abandon our attempts at integrating multiple international payment gateways. Instead, we created a system where users could upload their own payment information – credit card numbers, bank account details, and so on. We used a third-party library to handle encryption and validation, thinking this would solve our problem. But it turned out to be a disaster. We started getting reports of users' sensitive data being exposed due to a vulnerability in our custom implementation. The severity of the issue forced us to take down the entire platform until we could fix it. We learned that security is not something to be taken lightly, especially when dealing with sensitive information.
The Architecture Decision
We realized that we needed a more sustainable approach. We started exploring micro-services architecture, breaking down our payment processing into separate, independent components. We chose to use a Headless approach for our checkout system – building it as a separate application that accepts a user's payment information and then communicating with our main application to authenticate and complete the transaction.
We also started looking into payment processors like Paddle, Spreedly, and Bluesnap, which specialize in global e-commerce and offer features like multi-currency support, automatic exchange rate calculation, and, most importantly, the flexibility to work with different APIs. These companies handle the intricacies of payment processing, allowing us to focus on what we do best – building our platform.
What The Numbers Said After
After the necessary changes, our platform saw a 30% reduction in support tickets related to payment issues. Our users started reporting a smoother checkout experience, and our platform became more robust and secure. We also noticed a significant decrease in the number of failed transactions, which in turn led to a 25% increase in overall revenue. Our platform was finally able to serve users from all over the world, without any issues.
What I Would Do Differently
In hindsight, I would have explored the micro-services architecture and payment processor options earlier. I would have also invested more time and resources into proper security audits and testing, to prevent the vulnerability in our custom implementation. Lastly, I would have been more patient and not rushed our integrations, as trying to troubleshoot problems with multiple payment gateways was a nightmare.
Sustainable open source requires sustainable revenue. This is the payment infrastructure I use to collect that revenue without platform dependency: https://payhip.com/ref/dev9
