Connect Poshmark to SECND

Connect your Poshmark closet through the SECND Chrome extension.

Last updated 2026-05-24

TL;DR

Poshmark connects through the SECND Chrome extension. Install the extension, sign in to poshmark.com (or poshmark.ca) in the same browser, and the extension hands the session to SECND.

Before you start

You need the SECND Chrome extension installed in the browser you're using to manage your closet. Poshmark doesn't offer a public API for sellers, so SECND signs in the same way you do — through your live browser session.

Don't have the extension yet? See Connect with the SECND Chrome Extension for the install steps.

Step-by-step

1

Open Connect

In the SECND sidebar, click Connect. The page is titled Marketplaces.
SECND Marketplaces page with Connect buttons for every supported platform
2

Click Connect on the Poshmark card

Find Poshmark under Available and click Connect.
3

Sign in on poshmark.com

If you're not already signed in, the extension prompts you to open poshmark.com and log in. Canadian users land on poshmark.ca — that's fine.
4

Confirm Connected

Once signed in, the extension hands the session to SECND and the Poshmark card switches to Connected. No further approval is needed.

Heads up

Poshmark sessions can expire. If you see a “needs reauth” banner on the Marketplaces page, re-run the steps above — the extension picks up the new session automatically.

Settings to configure

Click the Poshmark card on the Marketplaces page. The Settings panel appears with the fields below.

Account Location

Read-only. SECND detects whether your closet is on poshmark.com (US, USD) or poshmark.ca (Canada, CAD) the first time it lists for you and shows the detected region here.

Accept Offers

When on, your listings allow buyers to send offers. Turn off if you want fixed prices only. Default: on.

Shipping Discount

Whether SECND attaches a shipping discount to new listings. Pick from Poshmark's discount options (e.g. $1 off, $3 off, free). Leave on None if buyers cover full shipping.

Include discount in price?

Only shows once a shipping discount is set. When on, SECND adds the discount amount onto the listing price so your net stays the same. When off, you absorb the discount.

Publish Status

Whether new listings publish to your closet immediately (Active) or stay as drafts (Draft) so you can review them in Poshmark before they go live.
