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.
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.
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.
| Platform | How you connect | Where listing / editing / removing runs | How sales are detected | Runs from Venda's servers? |
|---|---|---|---|---|
| eBay | Official API (OAuth) | Venda's servers via the API | eBay notifies Venda instantly | Yes (API only) |
| Etsy | Official API (OAuth) | Venda's servers via the API | Not automatic yet — mark the sale in Venda | Yes (API only) |
| Shopify | Official API (OAuth) | Venda's servers via the API | Shopify notifies Venda | Yes (API only) |
| Poshmark | Your own sign-in | Your device, in your session | Venda reads your public Poshmark listings (no login needed) | Only one case: if an item sold on Poshmark and your device hasn't removed it within 20 minutes, Venda's server completes that removal using your saved session |
| Mercari | Your own sign-in | Your device, in your session | Venda reads the public listing page (no login) | No — Venda's servers never act in your Mercari account |
| Depop | Your own sign-in (magic link) | Your device, in your session | Venda reads the public listing page (no login) | No |
| Facebook Marketplace | Your own sign-in | Your device, in your session | Venda reads the public listing page (no login) | No |
| Grailed | Your own sign-in | Listing and editing on your device; removals from Venda's servers using your saved session | Venda's servers check your listings using your saved session | Yes — sale checks and removals (Grailed removals from a phone proved unreliable, so Venda's server does them) |
| Whatnot | Your own sign-in | Your device, in your session (you tap the final Post) | Not automated yet — you mark the sale in Venda | No |
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:
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.
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.
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.
