I need a clean, well-documented integration that lets my in-house system talk to the eBay Inventory/Trading APIs so I can manage physical product listings without touching the web interface. The integration must cover two core actions only: • Add new listings (SKU, images, price, quantity, item specifics, shipping profile, etc.) • Update existing listings (price, quantity, description and any revised specifics) No delete or end-item logic is required at this stage. Once finished I expect: – OAuth application keys properly created and stored. – A lightweight script or micro-service (PHP, Node.js or Python—choose what you’re strongest with) that wraps the required endpoints. – Clear README explaining setup, environment variables and sample calls. – A quick screen-share or concise video showing a live call that creates a new listing, then a second call that edits it. Success is a repeatable workflow where my team can run a single command or hit a REST endpoint and see the listing appear or update on eBay within seconds, with all eBay responses logged for troubleshooting.

Hi, We’ve built similar integrations for eBay and Amazon, where we created a microservice to manage product listings and handle order fulfillment. We also developed a dedicated admin panel for managing product data and syncing it with the marketplace. For your project, we can use a lightweight PHP framework like Laravel Lumen or a Node.js microservice to create a robust solution. We’ll implement a fully automated OAuth flow to securely manage access tokens and refresh them as needed. We can also extend the integration to manage orders and automate fulfillment workflows, ensuring your team spends less time on manual tasks. Let’s schedule a 10-minute call to discuss your project in more detail and see if I’m the right fit. I usually respond within 10 minutes. Best regards, Adil

Hi, This is a clean and well-defined integration, and I can implement it reliably. I have 8+ years of experience working with APIs, including structured integrations, OAuth flows, and building lightweight services for automation. I’ll create a simple microservice (Node.js or PHP based on your preference) that wraps eBay Inventory/Trading APIs for two core actions: creating listings and updating them. The service will handle OAuth setup securely, token refresh, and structured request/response handling. Each call (add/update) will be exposed via a clear endpoint or command, with proper logging so your team can trace every request and response easily. I’ll also ensure fields like SKU, images, pricing, quantity, and item specifics are mapped cleanly and are easy to extend later. You’ll get clean, well-documented code, environment-based configuration, and sample requests so your team can start using it immediately. I’ll also demonstrate a live flow (create + update) so everything is clear and repeatable. The focus will be on simplicity, reliability, and easy maintenance. Let’s connect and I’ll walk you through the approach.

Hey, I read your requirements and understand that you need a reliable integration layer that lets your system create and update eBay listings programmatically without relying on the UI. I would implement this as a lightweight Node.js microservice (Express) wrapping eBay Inventory + Trading APIs. It will handle OAuth (token generation, refresh, secure storage), and expose clean REST endpoints like /create-listing and /update-listing. The service will map your internal product schema to eBay requirements (SKU, images, item specifics, pricing, shipping profiles), include structured logging for all API responses, and ensure near real-time updates. The codebase will be clean, modular, and fully documented with a step-by-step README and sample requests. A couple of quick questions: Are your products already structured with eBay-compatible item specifics/categories? Do you want sandbox-first testing or direct production rollout? This will give your team a repeatable, one-command workflow to instantly create or update listing. I would like to invite you in chat to discuss more and proceed further. Let's connect. Thanks!

I have designed several high-performance eBay API bridges for sellers managing thousands of SKUs, focusing on transitioning legacy workflows to the modern eBay RESTful Inventory and Fulfillment APIs. My prior work includes building custom synchronization engines that translate complex internal ERP data into eBay’s structured offer-and-inventory-item model, ensuring that listing updates are both atomic and reliable. By prioritizing OAuth 2.0 security and robust error-handling, I will ensure your integration remains stable through eBay’s frequent API versioning and policy updates. I will implement a decoupled middleware that utilizes the Inventory API for real-time stock and price updates, while leveraging the Fulfillment API for automated order retrieval and buyer communication. This includes a robust queuing system to manage high-volume updates without exceeding rate limit thresholds, paired with a persistent token management service that handles silent OAuth refreshes automatically. I’ll focus on mapping your in-house product schemas to eBay’s mandatory aspects, ensuring the system supports multi-location fulfillment and provides granular logging for every API interaction. This structured approach guarantees a clean, well-documented integration that allows your system to scale alongside your sales volume. Are you currently using a specific SQL-based architecture or a REST API for your internal data, and do you require support for bulk updates via Large Merchant Services? I would also like to discuss how you prefer to handle complex product variations and attribute mapping—feel free to message me here or hop on a brief call to align on the technical roadmap, specific documentation needs, and delivery timelines.
