Cross-list from Mercari to Poshmark
A Mercari listing is read out of Mercari by the extension, checked once in FlipDesk, then filled into Poshmark's own form by the browser extension — with the condition grade travelling with the item.
Getting the item out of Mercari
The extension reads your own Mercari closet and imports each listing as a FlipDesk item, with its photos, title, description and price.
What Poshmark needs
- Photos: Poshmark takes up to 16. If the item has more, the first 16 go, cover photo first.
- Title: 80 characters.
- Condition: Poshmark has its own list (NWT (New With Tags), NWOT (New Without Tags), EUC (Excellent Used Condition)…), so the condition is mapped rather than copied.
- Price: Poshmark takes whole dollars only, so a price with cents is rounded to the nearest dollar before it is sent.
- Size: every destination asks for its own size field. FlipDesk keeps the measurements with the item, so the size is filled from what you measured once rather than retyped.
Poshmark has no listing API for sellers. The GradeThread browser extension fills Poshmark's own listing form in your logged-in tab, and you press post.
The grade travels with the item
The listing that moves is not just words and photos. GradeThread grades the garment once on a published 1.0–10.0 scale and mints a certificate the buyer can check, and that grade rides into every channel the item is listed on — Poshmark included. It is the part a crosslisting tool cannot copy across for you, because it has nothing to copy: condition is the seller’s own word everywhere else.
Questions sellers ask
- Does the listing get removed from Mercari automatically?
- Not unless you ask for it. Cross-listing puts the item on Poshmark while it is still up on Mercari. When it sells on either one, FlipDesk ends the other listing so the same garment is not sold twice — on the channels with no API, that end runs in your own browser too.
- Do my photos come across?
- Yes. The closet import brings Mercari's own copies of your photos over with the listing, and Poshmark gets them in order, cover first.
- What about going the other way, Poshmark to Mercari?
- The same way. FlipDesk holds one catalog, so a channel is a destination and a source at the same time; nothing about the direction changes the steps.
