eBay products with variants

eBay manages variants through Inventory Item Groups — not a traditional variant resource. A Product Group links multiple individual products (SKUs) differentiated by aspects.

Prerequisites before publishing a product group

• Payoneer Account linked to your eBay account
• Enrolled in eBay Seller Program SELLING_POLICY_MANAGEMENT
• Fulfillment, Payment, and Returns Policies created
• At least one Location with a valid postal code

Steps to create and publish a product group

1. Create variant products in batch — POST /api/v1/products/batch with one entry per variant SKU.

2. Create the Product Group — POST /api/v1/products/{inventoryItemGroupKey}/variants linking all SKUs and defining variant aspects.

3. Create offers in batch — POST /api/v1/products/listings/batch with one offer per variant SKU, including policy IDs and merchant location.

4. Publish the group — POST /api/v1/products/{inventoryItemGroupKey}/variants/publish to make the entire group live on eBay.
