Connect Shopify to SECND
Connect your Shopify store using a custom app you create yourself.

TL;DR
Before you start
You need owner or staff-with-app-permissions access to your Shopify admin so you can create a custom app. SECND works with any Shopify plan.
Note
Create a Shopify custom app
In your Shopify admin, go to Settings → Apps and sales channels → Develop apps, then click Create an app. Name it “SECND” (or anything you like) and pick yourself as the developer.
In the new app, open Configuration → Admin API integration and grant these scopes:
read_products, write_products, read_inventory, write_inventory, read_orders, write_orders, read_locations, read_publications, write_publications, read_files, write_files.
Save, then open the API credentialstab. You'll see an API key and an API secret key. Keep this tab open — you'll paste both into SECND next.
Connect SECND
Open Connect

Fill in the three fields
yourstore.myshopify.com), the API key, and the API secret key from the custom app you just created.Approve on Shopify
Land back on Marketplaces
Settings to configure
Click the Shopify card on the Marketplaces page. The Settings panel appears in the right sidebar with the fields below.
Use Store Tags
When on, SECND uses the tags your Shopify store already applies to products instead of generating new ones. Leave on if you have a tag taxonomy you rely on for collections or filtering.
Publish Status
Whether new products SECND pushes are published to your storefront immediately (Active) or held back as Draft. Draft is the safe default while you're still tuning content.
Vendor Field
Whether Shopify's Vendor field is populated with the product's brand or your shop name. Use Brand if your storefront filters by brand; use Shop name if you resell consigned goods under your own banner.
Sales Channels
Which Shopify sales channels new products are published to: All channels, Selected channels (pick the list in the SECND desktop app), or Do not publish. Most stores leave this on All channels.
On Delist
What happens to the Shopify product when SECND delists it. Out of stock drops inventory to zero but keeps the product page live; Draft hides it from the storefront; Delete permanently removes it (SECND asks you to confirm).
