Build a Currency Converter Google Chat App with Google Apps Script (4)

In this part 4 of our tutorial on creating a Currency Converter Google Chat App in Google Apps Script we finally connect the Exchange Rate API to the /xe slash commands.

We will only face one tricky bit in this tutorial with how JavaScript handles rounding up decimal numbers with fives which we will cover in the video.

We will be returning more than just the basic exchange rate. We will return the one unit value from source to destination and then the same for a destination to source. We will also add in the date for convenience.
