How to Connect Shopify

Connecting Shopify to FLUF Connect

If you have a Shopify store, FLUF can help you crosslist to other marketplaces and keep everything in sync. Connection uses Shopify's Custom App method with an Admin API access token.

Prerequisites

Active Shopify store on any plan
Admin access to your Shopify admin panel
Your store's myshopify.com URL (e.g., yourstore.myshopify.com)

Connection Steps

Step 1: Navigate to Shopify Apps Development

Log into your Shopify admin panel
Navigate to Settings → Apps and sales channels
Click Develop apps (or App development on older Shopify versions)
If this is your first custom app, click Allow custom app development
Click Create an app

Step 2: Create "FLUF Connect" Custom App

App name: Enter FLUF Connect (or any name you prefer)

App developer: Select yourself or your development team

Click Create app

You'll be taken to the app configuration page

Step 3: Configure Admin API Scopes

Click Configure Admin API scopes

Scroll down and enable the following API access scopes:

Required scopes: - ✅ read_customers — Read customer data - ✅ write_customers — Write customer data - ✅ read_draft_orders — Read draft orders - ✅ write_draft_orders — Write draft orders - ✅ read_inventory — Read inventory - ✅ write_inventory — Write inventory - ✅ read_locations — Read store locations - ✅ read_orders — Read orders - ✅ write_orders — Write orders - ✅ read_products — Read products - ✅ write_products — Write products - ✅ read_product_listings — Read product listings - ✅ read_publications — Read publications

Click Save at the bottom of the scopes section

Step 4: Install the App and Get Access Token

Click Install app button at the top right

Confirm by clicking Install in the modal

After installation, you'll see Admin API access token section

Click Reveal token once (important: this only shows once!)

Copy the entire access token — it starts with shpat_

Store this token securely (you'll paste it into FLUF in the next step)

Critical: The access token is only shown once. If you lose it, you'll need to uninstall and reinstall the app to generate a new one.

Step 5: Connect in FLUF

Navigate to Connect → Channels

Click Add Channel and select Shopify

Enter your Shopify store URL (e.g., yourstore.myshopify.com)

Paste your Admin API access token (starts with shpat_)

Click Connect

FLUF will verify the token and scopes

Once verified, your Shopify channel card appears on the Channels page

What Happens After Connecting

✅ FLUF verifies your API access token and scopes

✅ Your existing Shopify products are imported (may take 5-15 minutes for large inventories)

✅ Webhooks are registered for real-time sync

✅ You can now crosslist Shopify products to other marketplaces

✅ Sales across all channels sync inventory back to Shopify

Webhooks Registered

FLUF sets up the following webhooks for real-time sync:

Product updates — When you edit products in Shopify

Inventory changes — When inventory levels change

New orders — When orders are placed on Shopify

Order cancellations — When orders are cancelled

Fulfillment updates — When orders are fulfilled

Inventory Locations

Shopify supports multiple inventory locations

FLUF syncs with your primary location by default

If you have multiple locations, configure which location to sync in Channel Settings

Changes made in FLUF update your selected location only

Product Variants

Shopify variants are fully supported

Each size/color variant can be crosslisted individually

Variant options (size, color) map automatically to marketplace-specific fields

Inventory syncs at the variant level (not just product level)

Collections

You can filter which Shopify collections sync to FLUF

Useful for separating:

- Wholesale vs. retail inventory

- Dropshipping vs. in-stock products - Private collections not for crosslisting

Configure collection filters in Channel Settings

After Connecting

Next steps to start crosslisting:

View synced products — See your Shopify inventory in FLUF

Create crosslistings — List Shopify products on eBay, Depop, Vinted

Manage orders — Centralize fulfillment across Shopify and marketplaces

View analytics — Compare Shopify performance vs. other channels

Troubleshooting

"Invalid access token" error?

Verify you copied the entire token (starts with shpat_)

Make sure you didn't include extra spaces when pasting

Check that the token wasn't truncated

If lost, uninstall and reinstall the app to generate a new token

"Missing required scopes" error?

Return to your Shopify app configuration

Go to Configure Admin API scopes

Ensure all required scopes listed in Step 3 are checked

Click Save and then Update the app

Try connecting again in FLUF

Products not importing?

Large inventories take 5-15 minutes to import

Check Channels for import progress

Ensure products are published to "Online Store" sales channel in Shopify

Draft products are not imported (must be active)

Webhooks not working?

Verify your Shopify plan supports webhooks (all paid plans do)

Check that the FLUF app is still installed in Shopify

Webhooks are automatically registered when you connect

Contact support if real-time sync isn't working

Need to reconnect?

Go to Channels

Click Disconnect on your Shopify card

In Shopify admin, go to Settings → Apps and sales channels → Develop apps

Delete the old "FLUF Connect" app

Follow Steps 1-5 above to create a fresh connection

Security Notes

Access tokens are encrypted and securely stored in FLUF's database

Tokens are never shared with third parties

You can revoke access anytime by uninstalling the app in Shopify

FLUF only requests the minimum scopes needed for crosslisting

API calls are logged for audit purposes
