Add a value to Numbers spreadsheet with a web service call
I am putting together a crypto coin financial spreadsheet and one of the values I want to use is the current value of Etherium which I can get from a simple web service call to a websites API ( https://min-api.cryptocompare.com/data/pricemulti?fsyms=ETH&tsyms=USD,USD). How to I add a function to the table to get and show the return value of this call? I know Excel has this functionality but I really don't like using Excel.
