I am working on E-commerce website and I am using craft commerce for that.Is there any way or any plugin available for that?
Craft cms provide a plugin to convert currency. Here is the link: https://github.com/leowebguy/craft-currency-converter
You can use this plugin as we have already used it and it's very easy to implement with Craft Commerce. You can convert the currency value using one line code in a twig template using this plugin. This plugin is using rapidapi for live currency rates.
I hope this will help.
