Install App 
ClaudeInstall the app
Use the official Marketplace listing and select the correct Webflow website.
Connect and configure
Follow the current app instructions, then map one product and its commerce actions.
Publish and test
Check the complete order flow on the published site, including mobile and payment errors.
Prepare a safe starting point
Use a staging copy or unpublished changes when you already have a live store. Identify the Webflow website and Penni Cart store that belong together. Create one product with real options and a price so your first test exercises a meaningful purchase.
Install through the Webflow app
Open the Penni Cart listing in the Webflow Marketplace and follow the app’s installation and connection flow. Use the current app and documentation instructions for your site; do not substitute the framework or plain HTML snippets unless the documented setup calls for them.
Connect the storefront elements
Follow the documented element attributes and product mapping. Verify that the displayed product, selected options and cart item agree. Design your cart and checkout with readable totals and useful error messages, then configure the payment provider and delivery rules you need.
Check the published experience
Designer previews are not a substitute for testing the deployed page. Publish to the intended test domain and check add-to-cart, quantity updates, checkout and a supported test payment. Confirm the final order has the expected information before opening the store to shoppers.
