Build Core E-Commerce Backend (Replacing Shopify) API, Orders, Inventory, Lynk WMS Integration

@AwaisChaudhry

Hello, I’m Muhammad Awais. I will build a clean, reliable PHP backend to replace Shopify, covering Orders, Checkout integration (payments handled separately), Product/SKU catalogue, Inventory sync, Fulfilment push to Lynk WMS, and Tracking/status updates back to your DB. My approach is API-first and modular: separate services for Orders, Inventory, Catalog, and Fulfillment with clear data contracts; a robust relational DB schema; idempotent operations; secure authentication; and a reliable event (webhook) and polling strategy to sync with Lynk WMS and your DB. I’ll implement thorough testing, migration planning from Shopify, and staged rollout to minimize risk. I’ll collaborate to define success metrics and SLAs and provide documentation and monitoring dashboards. To tailor the build, can you confirm: Lynk WMS API version and authentication method, data formats for orders and tracking; preferred event-driven vs polling for status updates; payment flow and how refunds/returns should be handled; data migration plan from Shopify and required data mappings; hosting, security standards (OAuth/JWT), and deployment SLAs. Best regards,
