Currencies API use case: E-commerce & global sales - Use Case

E-commerce

E-commerce works best when prices feel clear and consistent, no matter where customers are located. Accurate exchange rates help online stores display fair prices, calculate totals correctly, and avoid surprises at checkout when selling across borders.

Your challenge

Selling globally means dealing with constant currency changes that directly affect prices, margins, and customer trust.

Static exchange rates, delayed updates, or inconsistent FX sources can lead to incorrect pricing, confusing totals at checkout, and unexpected differences between what customers see and what they pay. Without reliable, up-to-date exchange rates — like those provided by the FinFeedAPI Currencies API, E-commerce platforms struggle to keep pricing accurate across regions and over time.
