Headless Digital Cookbook Commerce and Access Control Platform

Decoupled Architecture vs. Access Control

Standard Wix setups could not support the required custom catalog modeling, Cognito-based role/access management, nor the custom Next.js SSR workflows. The platform required a seamless bridge between hosted payment gateways and custom entitlement state management.

System Architecture and Implementation

AIKWARE designed an end-to-end serverless and event-driven architecture using AWS Amplify Gen 2 code-first infrastructure paired with Next.js App Router:

Wix eCom and digital Fulfillment Constraints

Wix Catalog V3 requires physical file uploads for digital products to be added to cart. To maintain Amplify Data as the single source of truth for all digital content, items had to sync down to Wix as physical SKUs solely for checkout feasibility. Also, official SDK checkout pathways initially returned 404s. This required custom public REST API integrations.

Checkout Metadata and Identity Linking

Custom checkout fields could not carry user unlock metadata without exposing internal technical attributes on the public hosted checkout form. Pending purchase records had to be keyed directly to Wix checkout IDs then synced downstream.

Caching, Asset Performance and DNS Complexities

Admin catalog modifications risked stale content across the Full Route Cache and Amplify CDN. Raw signed S3 catalog media added overhead. Domain cutover required navigating DNS apex/subdomain routing conflicts between Wix and Amplify CloudFront distributions without ALIAS/ANAME support on the Wix platform.

High-Performance Frontend and SSR (Next.js 16 + React 19)

• Built modular interfaces for the public storefront, customer unlock library, and administrative catalog management using Next.js App Router and Tailwind CSS 4.
• Utilized Server Components, Server Actions, and Next.js middleware integrated with Amazon Cognito session management for role-based route protection (Admin vs. Customer vs. Guest).
• Implemented tagged “use cache” public reads alongside path/tag revalidations triggered on catalog mutations to maintain strict cache consistency without stale content.

Cloud Infrastructure and Data Modeling (AWS Amplify Gen 2)

• Defined code-first infrastructure via defineBackend, leveraging Amazon Cognito with custom authentication challenge Lambdas for email and Google sign-in workflows.
• Modeled hierarchical data schemas (Book -> Chapter -> Recipe) with sync metadata and authorization rules in Amplify Data (AppSync / DynamoDB).
• Maintained public catalog read permissions via IAM identity pools while restricting content unlocks to verified Cognito owner attributes (sub).

Headless Checkout and Event-Driven Fulfillment Pipeline

• Catalog Synchronization: Authored Lambda workers that mirror catalog items to Wix Stores as physical SKUs to satisfy Wix checkout prerequisites while keeping core digital assets protected in Amplify Data and S3.
• Stateful Checkout Handoff: Engineered a checkout flow orchestrating Wix visitor OAuth tokens, direct REST checkout generation, and redirect domain configurations.
• Asynchronous Unlocks: Implemented secure Lambda Function URL webhooks listening for Wix order events. The handler validates paymentStatus === PAID, resolves the transaction against pending Purchase entities via checkout IDs. The handler then issues customer entitlements mapped to the authenticated Cognito user.

Media Optimization Pipeline

• Created a dedicated image optimization route using Sharp.
• Transforms private, signed S3 assets into responsive WebP formats on demand, adding edge/memory caching headers to cut latency and bandwidth costs.

Engineering Impact and Key Takeaways

• Modular Headless Execution: Demonstrated AIKWARE’S ability to link disparate SaaS ecosystems (Wix eCommerce) with enterprise AWS cloud architectures and Next.js web applications.
• Secure Access Control: Enforced multi-tier digital rights access control ensuring unauthenticated users browse public previews while recipe unlocks are strictly tied to authenticated payment verifications.
• Production-Grade Infrastructure: Established streamlined development-to-production deployment cycles using Amplify sandboxes, secret isolation (ampx secret), reproducible infrastructure-as-code, and documented operator runbooks.
