Adding an Exchange Rate Calculator

Hello, good people!

I was wondering what the best way to integrate an FX calculator into a website would be. Does anyone have any advice or tips? Should I use custom code or CMS? Is there an integration that can handle this? I added a link to what we are thinking about.

Any help would be greatly appreciated!

Using Javascript is the way to do it.
