API Versioning for Fintech: Best Practices, Pitfalls and the Industry Realities | Oluwatayo Farotimi

In this Builders in Fintech masterclass, we sit down with Oluwatayo Farotimi from Interswitch to unpack one of the critical parts of fintech infrastructure: API versioning.

Fintech products rely on APIs every single day, and as products scale, integrations multiply, and partners evolve, versioning becomes the backbone that keeps everything running smoothly.

In this session, Oluwatayo breaks down:

🔹 What API versioning really means in practice
🔹 Why fintech products break when versioning is poorly managed
🔹 How to plan and communicate version changes
🔹 Pitfalls and real-world challenges teams face when scaling
🔹 Best practices from Interswitch’s experience powering payments across Africa

You’ll also learn how versioning impacts product roadmaps, UX flows, partner integrations, and the customer experience, especially for teams building in the fast-moving African fintech ecosystem.

✔️ Engineers
✔️ Founders building payments, lending, wallets & infrastructure etc
