OfferUp Seller Listings API Documentation

GET https://scrappa.co/api/offerup/seller-listings?user_id=3827441&limit=20

Scrappa's GET /api/offerup/seller-listings endpoint returns every listing a seller currently has live on OfferUp.

Two differences from the other OfferUp endpoints

user_id is a string on this resolver and an integer on Seller Profile, which is an easy mistake to make.

limit is forwarded upstream here, but OfferUp is not trusted to stop exactly there and the page is returned whole, so count may exceed limit. That is deliberate: the returned page_cursor already points past everything the origin sent, so dropping rows to fit limit would make them unreachable. Paginate with page_cursor and treat count as the size of the page you actually received.

Use this to enrich seller views

Combined with Seller Profile, this gives a seller page both reputation and inventory in two calls. Listing detail for any returned listing_id comes from Item Details.

page_cursor is null on the last page. OfferUp does not always signal the last page reliably, so treat a null cursor as "no further page was offered" and stop the walk when a page adds no new listing ids. A page may contain more rows than the limit you asked for; keep walking until ids repeat.
