Gumroad Auth with ReactJS

Gumroad Official API docs: https://app.gumroad.com/api

Go to your gumroad profile -> Advanced -> Applications -> Create Application

You will get Application ID and Application Secret here.

Change .env.example to .env and Add value in .env file.

npm i
npm run start

After you click on Connect Gumroad button.

In App.js file, you can add your scopes, I have like these scope=view_profile+edit_products+view_sales

P.S. It's just for demo, so you must store App Id and App secret in Backend, not in FrontEnd.
