How Venda Connects

Last updated: September 21, 2026

Venda is built to work the way you do: your own login, your own device, your own session, at a human pace, with rate limits — and you can keep the final tap for yourself. Each marketplace sets and enforces its own rules for its sellers; we can't speak for them and we don't promise what a marketplace will or won't decide. What we can do is tell you exactly what Venda does on each one, so the decision is yours.

Two kinds of connection

Official API — eBay, Etsy, Shopify

You approve Venda on the marketplace's own consent screen. Venda's servers talk to the marketplace through its API, and you can revoke Venda in the marketplace at any time.

Your own sign-in — Poshmark, Mercari, Depop, Facebook Marketplace, Grailed, Whatnot

These marketplaces don't offer a public listing API. You sign in on the marketplace's own login page inside the Venda app (phone) or in a Venda-managed browser window (desktop). Venda never sees or stores your password. Venda keeps an encrypted copy of that login session.

Where your saved session lives

For the marketplaces you connect with your own sign-in, Venda keeps an encrypted copy of your login session — AES-256-GCM, in Venda's database in the United States. It is used only to:

  • restore your login on your own devices;
  • check your Grailed listings for sales and complete Grailed removals from our servers;
  • complete a Poshmark removal from our servers when an item sold on Poshmark and your device hasn't removed it within 20 minutes.

It is deleted when you disconnect the platform, delete your account, or tap "Delete saved login" in Settings → Platforms. Venda never asks for, sees, or stores marketplace passwords.

What you control

  • The final tap — On desktop, Settings → Assisted Posting → "Tap the final List/Post button myself". On mobile, autonomous publishing is off until you turn it on and accept the disclosure.
  • Delete saved login — Per platform, in Settings → Platforms (both apps). Automatic backups stay off until you sync again.
  • Disconnect — Removes the connection and the saved login.
  • Pace — Venda applies per-platform daily caps and minimum spacing between automated writes (shares, offers, relists, removals, posts) and only acts during daytime hours in your time zone when you've set one.
  • Category checks — Before posting, Venda checks each item against the marketplace's prohibited-items policy and won't post items a marketplace doesn't allow; it warns you on borderline categories.

Removals and the 2-minute target

When an item sells, our target is to remove it from every other marketplace within 2 minutes. Removals aren't guaranteed — a phone can be off, a marketplace can be down. If Venda can't confirm a removal within 2 minutes, the listing shows Action needed in the app and you get a reminder so you can finish it in one tap. You remain responsible for confirming an item is gone before it can sell twice.

Marketplace rules

Every marketplace publishes terms for its sellers, and every marketplace enforces them its own way. Venda is designed with those terms in scope: your login, your device, your session, human pacing, rate limits, and the option to keep the final tap. We don't use cloud bots or data-center browsers to post for you. Where a marketplace offers an official API, we use it (that's how eBay and Etsy work today), and we'll move any other marketplace to its API the day one opens.
