Create a Sheets Add-on To Sell

I walk you through the entire process as I create my own Sheets add-on called 'Steps Sheet' that provides the ability for users to connect to the FitBit API and pull their statistics into a Google Sheet.  In this book I'll show you how to:

Begin the add-on creation process

Set up a Google Cloud Platform project & link it to your add-on

Set up the oAuth consent screen in the Google Cloud Platform dashboard

Setup the callback URL for the oAuth authorization

Add the oAuth library to your project

Create the code that will perform the oAuth authorization

Make calls to the FitBit API

Hook into the Gumroad license key API

Take the steps needed to have your add-on published in the G Suite Marketplace
