Replacing Checkout
Use this approach when you want your server to redirect users to Simpler Checkout at the point where they would normally enter your CMS's native checkout.
A/B Testing Checkout
Before replacing your native checkout for every shopper, you can send only a share of them to Simpler Checkout and compare how each group converts on real traffic.
Cross-Login
A shopper who is already logged in to your store can arrive at Simpler Checkout already signed in, with their name, email and saved addresses filled in. Your integration hands Simpler a token identifying the shopper, and Simpler exchanges it for the shopper's profile by calling your /customer endpoint.
