We are looking for a developer with strong experience in the eBay API, specifically the Payment Dispute API. We currently have a Google Apps Script (GAS) + Google Sheets management system that tracks eBay case-open events. The system is already mostly complete, and the existing codebase (largely AI-assisted) is successfully retrieving standard case/open data. The remaining issue is retrieving Payment Dispute information correctly. ━━━━━━━━━━━━━━━ Current Situation ━━━━━━━━━━━━━━━ API in use: * eBay Sell Fulfillment API (Payment Dispute sub-API) Currently working: * /payment_dispute_summary → works correctly (HTTP 200) * /payment_dispute/{id} → works correctly with valid dispute IDs (HTTP 200) Problem: * /payment_dispute/search → returns HTTP 404 / 500 in production → endpoint exists in official eBay documentation, but does not function correctly in production OAuth scopes: * Required dispute-related scopes are already configured correctly Data we want to retrieve: * Dispute ID * Order ID * Buyer name * Amount * Reason * Status * Response deadline * Open date * Closed date * Seller protection eligibility Output destination: * Append to the existing Google Sheets case-management sheet ━━━━━━━━━━━━━━━ Important ━━━━━━━━━━━━━━━ This is NOT a full rebuild project. The existing system is already functioning, and we want to preserve the current structure as much as possible. We are specifically looking for someone who can isolate and fix the Payment Dispute retrieval portion only. Because eBay APIs can behave differently from the official documentation depending on environment, permissions, or production behavior, we strongly prefer developers with actual hands-on eBay API experience. If you have any questions, feel free to contact us. We look forward to hearing from you.
