eBay API Integration

Job ID: 40416137

Budget: £10 – £20 GBP

I need a developer to wire up my existing eBay developer account so I can:

• List brand-new products automatically
• Pull sales data in real time for reporting
• Sync my on-hand inventory with what is live on eBay

You are free to choose the most efficient stack—whether you prefer the official eBay REST SDK, direct REST calls, or a lightweight wrapper—but the end result must authenticate through my keys, handle OAuth refresh, and expose clean functions or endpoints for the three actions above.

Please build with clear, well-commented code and provide brief setup notes so I can drop new credentials into a config file and run. Once delivered, I’ll test by listing a sample item, fetching its sale (via sandbox or live), and updating stock; everything should reflect instantly on my seller dashboard.

If you’ve implemented the eBay API before, especially for new-item catalogs, you’ll be a perfect fit.
