Why doesn't Flippd sync with Poshmark, Mercari, Depop, Facebook Marketplace, Whatnot or Vinted?

Updated October 11, 2026

Because each marketplace decides which outside apps may read a seller's listings and sales, and today eBay is the only major one that lets an app like Flippd do it. Flippd syncs with eBay. For every other marketplace you track items yourself, which takes a few seconds per item, and Flippd still works out your fees and profit.

Here is where each marketplace stands, in plain terms.

eBay

eBay lets approved apps read a seller's listings and sales with the seller's permission, and has for years. That is why eBay is the one marketplace Flippd connects to. See How do I connect my eBay account to Flippd?.

Facebook Marketplace

Facebook offers no way for an outside app to see your personal Marketplace listings or sales. The connection Meta does offer is for business store catalogs, and Meta has been shutting even that down through 2026. There is nothing for Flippd to connect to.

Poshmark and Mercari

Neither Poshmark nor Mercari offers a connection for apps like Flippd. Tools that advertise Poshmark or Mercari sync work by running a browser add-on that reads your account for you. Mercari's rules say it can suspend sellers who use third-party tools on their account, and we are not willing to put your selling account at risk for a sync.

Depop

Depop offers a connection to a small number of approved partner companies. Flippd has asked Depop for access. If Depop approves us, Depop sync will work the same way eBay sync does: one way, into Flippd, never touching your listings.

Whatnot

Whatnot has a connection for sellers' tools, but it is not accepting new companies at the moment. We check back regularly. In the meantime see How do I track my Whatnot sales in Flippd?.

Vinted

Vinted only offers connections to large professional sellers who apply one at a time, so there is nothing an app like Flippd can connect to on your behalf.

How to Track These Platforms Today

Add the item to Flippd when you buy it, or import a spreadsheet of what you already have. See How do I import inventory from a CSV or spreadsheet?.
Mark it Listed and pick the platform. This is what drives the right fee estimate. See How do I mark an item as listed for sale?.
Mark it Sold when it sells, with the platform it sold on. Several at once is fine. See How do I record a sale and track my profit?.

Good to Know

Flippd never creates, edits or ends a listing on any marketplace, including eBay. See Does Flippd list my items on eBay, Whatnot, Poshmark, or Mercari?.
Picking the platform when you list or sell is enough for accurate fees. See What are the selling fees for eBay, Poshmark, Mercari, and other platforms?.
When a marketplace opens up, we will say so in the release notes. We do not announce dates before a marketplace has approved us.
