Once you have installed EasyPoints to your Store, you will find the application in your Shopify admin panel > Apps.
When you open EasyPoints app for the first time, you will go through the initial onboarding instructions. Please read through the instructions and warnings carefully and proceed to complete the onboarding.
During the onboarding, you will be asked to select between the Widget or Custom.
You can visit the demo stores to compare the differences:
Widget - https://easypoints-widget-demo-store-jp.myshopify.com
Custom - https://easypoints-demo-store-jp.myshopify.com
If you select Custom, please see the Integration Guide for more details about the Custom Setup Process.
You will still have the option to change your mind later if you don't select custom during the onboarding.
