FAQ
Do I need Shopify Plus for Checkout Extensibility?
Shopify Plus is required for Checkout UI extensions on the information, shipping, and payment steps. However, 'Thank You' and 'Order Status' page extensions are available on all plans except Shopify Starter. I can verify your plan eligibility before we start.
Can you migrate my old checkout.liquid or Shopify Scripts?
Yes. I can review your existing customizations and migrate supported functionality to Checkout UI extensions or Shopify Functions. Keep in mind that some legacy features may need to be redesigned to work within Shopify’s supported modern capabilities.
Can you integrate external APIs or custom loyalty apps into checkout?
Yes, where Shopify’s APIs and permissions allow. I can connect checkout extensions to external services to display data like loyalty rewards. Please note that secure integrations may require a custom app backend, network-access approvals, and specific customer-data permissions.
Will these checkout modifications break my current theme?
Checkout UI extensions run completely separately from your storefront theme and generally do not require theme-code changes. They are designed to work within Shopify’s supported framework, and I rigorously test the implementation for compatibility and performance before launch.
What do you need from me to get started?
I will need appropriate collaborator access, a clear description of your requirements, and API documentation if third-party services are involved. I will only request the specific store permissions necessary for the project, and any credentials should be shared securely.
