Smart Order & Inventory API

@rinsadsl

Hello, Good Day! I’m very interested in building this Smart Order & Inventory API for your Wix store. This is a strong backend systems project, and I can help you design it from scratch as a clean, API-first service that receives Wix orders, checks stock and pricing across your selected stores, recommends the best fulfillment option, updates inventory logic, and triggers alerts when thresholds or unusual sales activity occur. For this kind of workflow, I would recommend Node.js with PostgreSQL because it is well suited for webhook-based order intake, fast decision logic, scalable API development, and reliable relational data handling. I would structure the system around clear endpoints for orders, inventory, pricing, fulfillment decisions, and alerts, with proper webhook validation, API authentication, rate limiting, and detailed logging. The first milestone can focus on a working proof of concept where a Wix order is received, item availability is checked, and the API returns the best store recommendation for fulfillment. I have experience building backend automation, integrations, and decision-based workflows where reliability and clear data flow matter. I can deliver a documented repository, setup instructions, API collection, and deployment guide so the system is easy to run and extend later. Kind Regards, Rinsad

Hi, This is a solid system design problem—not just a website—and I’ve built similar order-routing + inventory decision engines. Here’s exactly how I’d approach your setup (Wix → central API → multi-store fulfillment). ? Architecture (built for Wix) Stack: Node.js (Fastify) + PostgreSQL + Redis Why: Wix can push orders via webhooks → REST API Fastify = high performance for real-time decisions PostgreSQL = strong relational model (orders, stores, inventory) Redis = caching + rate limiting + spike detection

Hi there, I have checked your requirements where you mentioned that you want to build a inventory api for your project…..Please invite me in chat so we can discuss in detail….

@diektech

Hi, This is Elias from Miami. I checked your project description and understand you want a central backend service built from scratch that receives Wix orders, checks live item availability and pricing across nearby stores, recommends the best fulfillment source, updates stock logic, and triggers alerts when inventory gets low or sales activity looks unusual. I’d approach this by building the order flow first as the initial milestone: Wix order webhook/API intake → product normalization → store availability/price comparison → fulfillment recommendation response, then expand into inventory sync, alerting, and external dashboard-ready endpoints. I’ve worked on backend systems that connect storefront events, inventory logic, third-party integrations, and alert workflows, so I understand the importance of keeping the API clean, reliable, I have a few questions to get a better understanding: Q1 – For Walmart, BJ’s, Wegmans, Stop & Shop, Sam’s Club, Costco, and ShopRite, do you already have official APIs, partner access, or will this availability/pricing layer need to rely on custom integrations? Q2 – Should the first version recommend a single best store per item/cart, or support split-cart fulfillment when different items are only available at different stores? Q3 – For alerts, do you want email/SMS notifications first, and what exact events should trigger them beyond low stock and unusual sales spikes? Looking forward to hearing from you.

Hi there, I will build your Smart Order & Inventory API — Wix webhook ingestion, multi-store stock lookup across Walmart, BJs, Wegmans, Stop & Shop, Sam's Club, Costco, and ShopRite, fulfillment routing by availability and price, and threshold-based alerts. For the architecture, I will use Node.js with Supabase (Postgres + edge functions) — it pairs well with Wix webhooks, gives you real-time database listeners for inventory alerts, and exposes a clean REST layer you can wire into any dashboard later. Each retailer needs a different data strategy since none offer open inventory APIs — I will build per-store adapter modules so adding or swapping a retailer does not break the core routing logic. Send me a message and we can go over the details. Best regards, Kamran

@AITSoft

Hello, I understand you need a robust API that handles orders from your Wix storefront by checking real-time stock and prices across multiple stores, then selecting the best store to fulfill each order. The system will also update inventory and alert you when stock is low or sales suddenly rise. My approach will build a clean, well-documented REST or GraphQL API from scratch, using a reliable backend like Node.js with PostgreSQL or Supabase, ensuring smooth order flow, fast data syncing, and secure handling of authentication and rate limits. I'll design endpoints for orders, inventory, pricing, and alerts, automate inventory updates for all your store partnerships, and set up multiple alert options like email and push notifications. Along with code, you’ll get setup instructions and API documentation for easy deployment and expansion. Which store APIs provide real-time inventory and price updates or will that data be managed directly in the system? Do you have preferred cloud hosting or any limitations on third-party service integrations? How should manual payments be processed and linked within the order API? What specific alert triggers and frequency are needed for sales spikes? Are there any security standards or user roles you want built into the authentication process? Which stores provide official APIs for real-time stock and price data, or will these details be maintained manually or through another system? Thanks,

@iosifpeterfi

I'm Iosif Peterfi, 15+ years delivering practical, security-minded solutions that keep business moving. This is my speciality: orchestrating end-to-end order and inventory flows across multiple locations with clear interfaces and risk-aware dashboards that speed decisions and reduce stockouts. You're building a central API to receive Wix orders, check real-time stock across three nearby locations, compare availability and price, and decide which store fulfills the sale. Once chosen, it must decrement inventory and raise quick alerts when stock dips below a threshold or sales spike unusually. With no backend yet, the full pipeline for orders, inventory, pricing, and alerts must be built from scratch, plus a clean REST or GraphQL interface that can feed a future dashboard. The initial milestone should prove that a Wix order can travel through the API, fetch inventory data, and return a recommended store. I'll deliver a lean, scalable API layer that sits between your Wix storefront and your stores, delivering fast, observable decisions that reduce stockouts and improve fulfillment reliability. Key outcomes: a single source of truth for orders, inventory, and pricing across three locations; a deterministic routing decision; and real-time alerts. Deliverables include a REST or GraphQL surface, endpoints for orders, inventory, pricing, and alerts, a simple inventory-sync mechanism across stores, and alert channels.

@johnallenvillan1

Hi, I noticed your priority is proving that a Wix order can flow through a new API, query real‑time stock across your listed stores, and return the correct fulfillment location with clean documentation. I’ve built similar multi‑location inventory routers where I integrated storefront webhooks, normalized inventory data, and delivered instant routing decisions; one recent project handled three suppliers and cut stock‑related order exceptions by 40%. The real challenge here is ensuring consistent inventory truth across Walmart, BJs, Wegmans, Stop & Shop, Sams Club, Costco, and ShopRite while avoiding race conditions when multiple carts update stock at once. A junior dev would overlook concurrency, webhook retries, and price drift between vendors. I’ll create a Node.js service with a structured routing layer, real‑time sync workers, and REST endpoints for orders, inventory, pricing, and alerts. I’ll implement auth via signed keys, rate limiting at the edge, and webhook validation for Wix. Inventory decrementing and threshold alerts will run through queued tasks to stay consistent. Before finalizing the stack, I need clarity on how you currently access inventory and pricing from each store. Sincerely, John allen.

@vipinjain1213

The part that usually breaks in systems like this is the decision layer. Picking the right store sounds simple, but when price, stock, and partial cart fulfillment mix, logic can get messy fast. If that layer isn’t clean, everything downstream becomes unreliable. I’d structure this as a central Node.js API with a clear decision engine. Orders come in from Wix via webhook, inventory is checked across stores, and the system returns the best fulfillment option based on rules you define. Partial cart handling will be important here since items may come from different stores. Inventory sync would run both on demand during order checks and via background jobs to keep data fresh. Alerts for low stock or unusual spikes can trigger through email or SMS instantly. I’d also keep the API clean with proper auth, rate limits, and a documented set of endpoints so you can plug in a dashboard later without rework. I’ve built backend systems and APIs with similar decision logic and real-time flows, so this structure is very familiar. One thing I want to clarify first, when a cart has items from multiple stores, do you want the system to split the order automatically or always try to prioritize a single store even if pricing is slightly higher?

@reedsystems

Hi, I'm excited to propose my solution for your project. Given the requirements, here's a concise overview: Architecture Choice and Integration with Wix I'll use Node.js alongside PostgreSQL for database management, as it provides robust performance and ease of integration. This stack aligns well with Wix’s API capabilities through clear REST endpoints. Authentication, Rate Limits, Webhooks For authentication, I’ll implement JWT tokens to secure the API. Rate limits will be handled using Redis to manage requests efficiently without overloading servers. Webhooks from Wix will trigger order validation and stock check processes. Endpoints Required - Orders: `/orders/create` for receiving new orders. - Inventory: `/inventory/check/:store_id` for checking stock availability. - Pricing: `/pricing/get/:store_id` to fetch current prices. - Alerts: `/alerts/send/:type` for sending alerts via email, SMS, or push notifications. Inventory Sync Logic A scheduled task will run every 5 minutes to synchronize inventory levels across all stores. If a store’s stock drops below a threshold, it triggers an alert through the specified mechanism. Alert Mechanisms - Email: For detailed reports. - SMS: Quick notifications for urgent issues. - Push Notifications: Real-time updates for both me and key stakeholders. Deliverables The deliverable will be a fully functional repository with clear setup instructions, Postman collection for testing, and a deployment guide to run it on your preferred cloud host. A quick proof-of-concept order flow will be provided as requested. Feel free to review this proposal or reach out if you have any questions! https://www.freelancer.com/u/reedsystems
