Set up marketplace feeds (Amazon, eBay, OnBuy)

Marketplaces each have their own listing requirements, but the source data is the same catalogue. Trajekt formats your products for each and keeps them in step with your store.

How marketplace feeds differ

Unlike ad channels, marketplaces list and sell your products directly, so identifiers and category accuracy matter even more. GTINs are usually mandatory, and category or attribute requirements are stricter.

Amazon

Trajekt produces formatted product data you can use for Amazon listings and Sponsored Products. Make sure every product has a valid GTIN/EAN, as Amazon matching depends on it.

eBay & OnBuy

For eBay and OnBuy, Trajekt keeps listing data — price, stock, title and images — in sync with your store on each refresh, so you're not maintaining separate spreadsheets per marketplace. OnBuy in particular is a fast-growing UK marketplace worth testing.
