Connect Shopify to Suppli

This guide walks you through creating a Shopify custom app, getting API credentials, and linking them to Suppli so your inventory syncs automatically.

Go to your Shopify admin

Open your Shopify store admin and navigate to Settings → Apps and sales channels → Develop apps.

⚠️ If you don't see "Develop apps", enable developer mode. There is a toggle button on that screen.

Create a custom app

Click Create an app. Give it a name like "Suppli Sync". Click Create app.

Set API scopes

Click Configure Admin API scopes and enable the following permissions:

write_inventory
read_inventory
read_products
write_products

ℹ️ write_products is needed if you use auto-draft — Suppli changes the product status from Active to Draft when stock hits zero.

Save the scopes, then click Install app.

Copy your Admin API token

After installing, go to the API credentials tab. Under "Admin API access token", click Reveal token once and copy it.

⚠️ You can only see the token once. Copy it now and store it somewhere safe. If you lose it, you'll need to create a new app.

Find your Location ID

In Shopify admin go to Settings → Locations. Click your location name. The URL will contain the location ID:

https://admin.shopify.com/store/yourstore/settings/locations/1234567890

Copy that number — it's your location ID.

Add your store domain

Your store handle is the part before .myshopify.com. For example:

https://my-store.myshopify.com → handle is my-store

Enter credentials in Suppli

In Suppli, go to Channels → New Connection. Select Shopify as the platform and enter:

Store handle (e.g. my-store)
Admin API token (from step 4)
Location ID (from step 5)

Check SKU matching

Suppli matches inventory by SKU. Make sure the SKUs in your Shopify product variants exactly match the Internal SKU you set in Suppli's product mappings.

ℹ️ SKU matching is case-sensitive. "BP799" and "bp799" are treated as different SKUs.

Test with a manual sync

Upload a test feed CSV in Suppli and trigger a sync. Check the Sync Logs for any errors. Then verify the inventory updated in your Shopify admin under the product variant.
