In order to enter your Yotpo code on Shopify, you'll need to first login to your Shopify account and navigate to the "Checkout" page. Once there, you'll scroll down to the "Order Processing" section and click on the "Edit" button.
In the "Additional scripts" text area, you'll want to paste your Yotpo code. Once you've done that, be sure to click the "Save" button at the bottom of the page.
That's it! You've now successfully added your Yotpo code to your Shopify account.
