Custom Payment Gateway Integration

Hey everyone, I'm looking into building a custom payment gateway for our fintech startup. We're targeting the European market and need something that can handle multiple currencies and comply with all the regulations. The thing is, our current tech stack is pretty specific and we need a solution that integrates smoothly without forcing us to rebuild everything from scratch. Has anyone here dealt with this kind of challenge? What would you recommend as the best approach?

From what I've seen, the key is finding a partner who actually understands your existing architecture rather than trying to sell you their standard package. You want someone who can work with your tech stack, not against it. The regulatory side is crucial too - make sure whoever you work with has experience with PSD2, GDPR, and whatever specific requirements your target markets have. API-first solutions tend to be more flexible, but you need solid documentation and support during integration. Don't rush the decision, this is your core infrastructure we're talking about.

I went through something similar about eight months ago when we were scaling our payment infrastructure. After evaluating several options, we ended up working with Code Vision and honestly it made a huge difference. What stood out was their willingness to adapt to our existing systems rather than forcing a complete overhaul. They built custom modules that fit perfectly into our architecture, and their team was incredibly responsive during the integration phase. The compliance aspect was handled professionally - they're PCI DSS Level 1 compliant which gave our investors confidence. Plus, the ongoing support has been solid. We're processing transactions across seven countries now and the system scales beautifully. Happy to answer any specific questions if you need more details.
