eBay API Integration

@Microlent

eBay integrations often look simple, but the real work is in handling OAuth refresh, keeping inventory in sync without conflicts, and mapping listing data correctly to eBay’s schema. I’ve worked on similar API integrations where the focus was reliable automation and clean, reusable endpoints, not just one-off scripts. I can help with: Secure OAuth setup (token handling + auto refresh) Product listing automation (new items, correct category + schema mapping) Real-time sales data fetching (orders, transactions) Inventory sync (update stock accurately, avoid overselling) Clean API layer/functions for all three actions Well-structured, commented code + simple config for credentials Stack (recommended): Node.js or Python (lightweight, easy to extend) Direct eBay REST APIs (no unnecessary wrappers) You’ll get:Ready-to-run codebase Clear setup guide (drop keys → run) Tested flow (list → fetch sale → update stock) For similar work and integrations: https://www.freelancer.com/u/Microlent Can start quickly and deliver a working integration you can reuse and scale. — Rajesh Rolen

Hi, I can wire up your eBay developer account so your system can handle automated listings, real-time sales data, and inventory sync. I will implement clean integration using the official eBay REST APIs with OAuth handling, including token refresh so your connection stays stable without manual re-authentication. The solution will include three core modules: automated product listing, real-time sales reporting, and inventory synchronization with your eBay store. These will be exposed as simple functions or endpoints so you can plug them into your existing system easily. I will structure the code in a clean, well-commented way so you can drop in your credentials through a config file and run it immediately without complex setup. I will also include setup notes so you can test everything quickly using sandbox or live environment, including listing a product, checking sales data, and updating stock with instant reflection in your seller dashboard. If needed, I can also help you extend this later into bulk listing automation or multi-channel inventory sync.

@uniqedeveloper

Hi, I totally understand your requirement—you need a clean, reliable eBay API integration for listing, real-time sales fetch, and inventory sync with proper OAuth handling. I’ve done a similar build for a retail client where I integrated eBay REST APIs (Inventory + Fulfillment), automated product listings, and synced stock via webhooks—ensuring near real-time dashboard reflection. I’ll implement secure OAuth (auto-refresh tokens), and expose clear endpoints/functions: * createListing() for new items * getSales() for orders/transactions * syncInventory() for stock updates Stack: Node.js or Python (your preference), eBay REST APIs, webhook listeners for instant updates, structured config for easy key swap. Code will be modular, documented, and sandbox-tested before live. Quick questions: 1. Preferred runtime (Node or Python)? 2. Do you want webhook-based real-time sync or polling fallback? 3. SKU structure already mapped to your inventory system? Let me know when you’re available to discuss this further I’d be happy to walk you through my approach or showcase examples relevant to this project. Looking forward to hearing from you! Best regards, Mulayam

@mhmamun360

Hi, You need a reliable eBay API integration that automates product listing, real-time sales tracking, and inventory sync with secure OAuth handling. I’ll build a clean Node.js (or Python) module using eBay REST APIs with OAuth token refresh, exposing functions/endpoints for listing items, fetching orders/sales, and updating stock instantly. The code will be well-commented, config-driven, and ready for sandbox/live testing. I have experience integrating third-party APIs with secure auth flows and real-time data handling. As a bonus, I’ll include logging and error-handling for smooth debugging and stability. Do you prefer a simple script-based setup or a small API service for easier scaling later? https://www.freelancer.com.bd/u/mhmamun360 Best regards, Md Mamun Hossain

@carlosd178

Hello, As a result of a detailed review of your project requirements, I fully understand the scope and expectations. I can wire up your existing eBay developer account to list new products, pull sales data, and sync inventory through clean API functions/endpoints. I’m available to start your project right now. I bring deep expertise in PHP, MySQL, eBay API, OAuth, REST API, API Integration, API Development, Software Architecture with over 10 years of experience. One key challenge here is handling OAuth refresh properly while keeping product listing, sales reporting, and inventory updates reliable. I would build a lightweight REST-based integration with a config-driven credential setup, token refresh handling, clear endpoint structure, and well-commented code so you can test sample listing, sales fetch, and stock update easily. I have a couple of quick questions. • Do you prefer PHP/MySQL for the implementation, or is Node.js also acceptable? • Should the first version target eBay Sandbox first, then switch to live credentials after testing? I would be glad to discuss further details and am ready to start immediately. Looking forward to hearing from you. Best regards, Carlos.
