In this article, we will introduce ExchangeRatesApi.io, a popular API solution providing data for current and historical exchange rates for 168 currencies. Thanks to APIs providing currency exchange data, we can add a currency convertor to our online shops rather effortlessly. This means that we can’t have a pre-defined list of exchange rates stored in our application these must be gathered in real-time. To achieve that, we can convert the price of the item from a base currency (say, EUR) to the visitor’s currency (say, CNY) using the exchange rate between the two currencies at that specific time.Ĭurrency exchange rates change constantly, on an hourly basis (and even faster). If we want to provide a great user experience for them, to increase the chances of them buying our product, and coming back to the site, there is something very simple we can do: Display the price of the shopping items in their own currency. As we live in a global village, if we have an online shop, many of our visitors will quite likely be based on a different country than our own, and use a different currency than our own.
Products and services are increasingly accessed and bought online. This article has been kindly supported by our dear friends at ExchangeRatesApi.io who provide developers with powerful data and conversion APIs for current and historical exchange rates.
