As a developer deeply invested in the security and efficiency of web applications, I've found Stripe to be a robust solution for handling online payments. The API and SDKs are well-documented, making integration relatively seamless. I've particularly appreciated Stripe's strong emphasis on security, especially its built-in support for OAuth and JWT for authentication, which aligns well with best practices in secure app development. This is crucial in a landscape where payment information is a prime target for fraud. Additionally, their webhook system is very versatile, allowing for real-time notifications on events which makes the payment process interactive and easily monitored. However, during peak usage, I've observed some latency issues which could be critical depending on the transaction urgency.
