Create a page on your Shopify store (e.g., yourstore.com/pages/wedding-invitation) and paste this single HTML file into a Custom Liquid block. Because all 4 details + the religion theme live inside the URL itself, every customer gets a permanent, unique link they can forward to unlimited guests on WhatsApp—without needing any external database!
Method 2: Saving the 4 Details in Shopify Orders (Line Item Properties)
If you sell this invitation as a digital product on Shopify, you can use standard Shopify Line Item Properties (`properties[Religion Theme]`, `properties[Bride & Groom]`, `properties[Wedding Date]`, `properties[Venue Address]`, `properties[Google Maps Link]`) on your product page. Shopify automatically saves those 4 fields inside the customer's Order in your Shopify Admin forever, and your order confirmation email can automatically output their personalized link!
