Getting Started

Quick Start: Your First 15 Minutes

Sign up, connect a marketplace, import your listings, and cross-list your first item using the dashboard's Get set up checklist.

Last updated 2026-05-24

TL;DR

Sign up at secnd.ca, then work through the "Get set up" checklist on your dashboard: finish account setup, connect a marketplace, import your listings, cross-list one item, and turn on one automation. Most of the wall-clock time is the initial import running in the background.

What you'll need

Before you start, have these ready:

  • A working email address (or a Google / Apple account if you prefer social sign-in).
  • Login credentials for at least one marketplace you already sell on — eBay, Etsy, Shopify, Poshmark, Depop, Grailed, Square, Lightspeed, or Facebook Marketplace.
  • Google Chrome on a desktop if you plan to connect Poshmark, Depop, Grailed, or Facebook Marketplace — those use the SECND Chrome extension for passwordless connection.

Step 1: Sign up at secnd.ca

1

Create your account

Open secnd.ca/sign-up and either click Sign up with Google / Sign up with Apple or fill in your email and password. Click Sign up.

Step 2: Sign in

Sign in with the credentials you just created

Social sign-ins are signed in automatically. For email + password, go to secnd.ca/sign-in, enter your details, and click Sign in.

Step 3: Open the dashboard

Signing in drops you on the SECND dashboard. The top card is Get set up— a five-task checklist that takes you from empty workspace to first cross-listed item. Work through it from top to bottom.

Meet the Get set up checklist

The five tasks are: Finish account setup, Connect a marketplace, Import your existing listings, Cross-list your first item, and Turn on an automation. Each task links to the right page; tasks tick off as you complete them.

Note

The sidebar shows the rest of SECND: Dashboard, Products, Orders, Automations, Delist History, Listing Manager, and Connect. You'll revisit these constantly once you're set up.

Step 4: Finish account setup

4

Click ‘Finish account setup’

This is checklist task #1. Click the link in the Get set up card. The account setup screen collects basic shop details — the universal defaults SECND uses across every marketplace. Fill them in and save.

Step 5: Connect a marketplace

Click Connect in the sidebar. The page is titled Marketplaces and shows every platform SECND supports as a tile under Available.

5

Pick a marketplace and click Connect

Start with the marketplace where most of your current sales happen — see Which marketplace should you connect first? if you're unsure.

6

Authorize SECND on the marketplace

eBay, Etsy, Square, and Lightspeed open an OAuth consent screen. Sign in to that marketplace and approve. Shopify uses a custom app you create yourself — see Connect Shopify for that flow.
7

Poshmark, Depop, Grailed, Facebook: install the Chrome extension

These marketplaces don't expose OAuth, so SECND uses a passwordless Chrome extension instead. If you're connecting one of these, see Connect with the SECND Chrome extension for the install + sign-in flow.

Step 6: Import your existing listings

Once a marketplace is connected, SECND starts pulling your active listings. The Get set up task Import your existing listings (#3) links to the import flow.

8

Watch the import progress

Import runs server-side — you can close the tab and come back later. When the Products page shows your inventory, the import is done. See Importing your inventory for what to do if anything looks off.

Step 7: Cross-list your first item

9

Open the first listing

From Products, pick any imported item and open it.
10

Pick another marketplace and publish

In the listing detail view, choose another marketplace to publish to. SECND copies the title, description, price, and images, applies the marketplace-specific defaults you set when connecting, and shows a preview. Click Publish.
11

Verify on the marketplace

The listing appears on the second marketplace within a few minutes. Refresh the marketplace itself to confirm.

Good to know

That's task #4 done. You're officially cross-listing.

Step 8: Turn on an automation

The last Get set up task (#5) is to turn on at least one automation. Automations run in the background — auto-delist when an item sells elsewhere, auto-import new listings, scheduled cross-lists, and so on.

12

Open Automations

Click Automations in the sidebar.
13

Create or enable one

Pick an automation type, configure which marketplaces it applies to, and save. See Building your first workflow for a walk-through of the automation builder.

Good to know

You've completed the Get set up checklist. SECND is now keeping inventory in sync, importing in the background, and listening for sales on every connected channel. Open the Assistantat the bottom of the sidebar any time you have a question — see The SECND AI Assistant.
