Every marketplace does not work the same way.
Only eBay offers a public API for third-party publishing. For the other four, Garage Sail produces a marketplace-tuned listing you paste into the marketplace's own form. Here's the honest breakdown.
| Marketplace | Direct publish | Copy-ready | Prefilled form | Best for |
|---|---|---|---|---|
| eBay | Yes | Electronics, collectibles, sneakers, trading cards, tools | ||
| Facebook Marketplace | No API | Furniture, appliances, exercise equipment, bikes | ||
| Mercari | No API | Clothing, accessories, small home goods | ||
| OfferUp | No API | Furniture, electronics, tools, sporting goods | ||
| Craigslist | No API | Furniture, vehicles, appliances, building materials |
