Already crosslisting somewhere else? Import your closet and list once to Poshmark, eBay, Mercari, Depop, Vinted and Shopify. Edit, delist and sold-sync stay in step across every marketplace — with Poshmark auto-share on top. Official APIs where they exist, your own logged-in browser session everywhere else.
Free core, no card. Closo never stores your marketplace passwords.
The same core everywhere — list, edit, delist and sold-sync — but the connection differs by marketplace, and we don't pretend otherwise. Here's exactly how each one works.
Where most of our sellers start — the Poshmark-first home base for your closet.
How it connects: the browser extension acts through your existing Poshmark session — the one you're already logged into. No password is ever stored. Auto-Share is an Unlimited agent.
The largest US marketplace — connected the official, sanctioned way.
How it connects: you authorize Closo through eBay's official OAuth — a one-tap connect, no password shared, revoke access from eBay anytime.
High-volume US resale — one more channel from the same draft.
How it connects: the browser extension works through your existing Mercari session. Nothing to paste, no password stored.
Style-led resale for streetwear and vintage — reaches a younger buyer.
Good to know: Depop has no separate title field — the title is the description, so Closo maps them together. Connects through your existing Depop session; no password stored.
No-seller-fee resale with a big buyer base — one more channel from the same draft.
How it connects: the browser extension works through your existing Vinted session. No password is stored.
Your own storefront — keep it stocked from the same catalog you crosslist everywhere else.
How it connects: connect your store through Shopify's official app authorization — a standard OAuth handshake, no password shared.
Some marketplaces offer an official seller API. Some don't. Rather than fake it, Closo uses the right method for each — and never touches your password either way.
You authorize Closo through the marketplace's own OAuth screen. It's the sanctioned integration: no password is ever shared with Closo, and you can revoke access from your marketplace account at any time.
Where there's no seller API, the Closo browser extension acts through the session you're already logged into — the same way you'd click through the site yourself, just automated. You stay signed in on the marketplace; Closo never sees or stores your password.
Closo never asks for, sees or stores your marketplace passwords — API tokens and your existing sessions do the work.
Revoke API access or remove the extension whenever you want. Nothing runs without you being signed in on your own machine.
Edit an item once and push the change out. When it sells on one marketplace, Closo can delist it on the others.
Straight answer: Closo doesn't crosslist to Etsy, TikTok Shop or Whatnot yet — all three are on the roadmap and we're adding them soon. For now Closo covers the six above — Poshmark, eBay, Mercari, Depop, Vinted and Shopify — with these next.
Free core, no card, and your passwords never leave you. Start listing across all six today.
