Connecting Existing Products
Already have products in your Shopify store? PromoSync can work with your existing catalog — not just freshly imported products. You just need to link them to their supplier records so that automated inventory and pricing sync can kick in.
The Problem
Products added to Shopify outside of PromoSync don’t have the PSRESTful metafields that power automated sync. Without these metafields, PromoSync has no way to match your Shopify products to the correct supplier SKUs, so inventory levels and pricing won’t update automatically.
The Solution
Connecting your existing products is a three-step process:
1. Export from PSRESTful CSV Exporter
Use the PSRESTful CSV Exporter to export product data in the Extra ID format. This format includes Shopify-compatible identifiers (like product handles and variant SKUs) that allow you to match exported records to products already in your store.
2. Bulk-Update with Matrixtify
Use Matrixtify (or a similar bulk-import app) to update your existing Shopify products with the exported CSV data. This step writes the required PSRESTful metafields onto each product and variant, linking them to the correct supplier records.
Matrixtify’s merge mode updates existing products by matching on handle or SKU — it won’t create duplicates.
3. Sync Duplicate Products
After the metafields are in place, run the Sync Duplicate Products bulk action inside PromoSync. This synchronizes the linked products, populates any remaining metafields, and enables automated inventory and pricing updates going forward.
What Happens Next
Once connected, your existing products behave exactly like products imported through PromoSync:
- Inventory syncs automatically based on your inventory settings
- Pricing updates follow your custom pricing rules
- Product data refreshes on your configured schedule
This workflow involves bulk-updating metafields across your catalog. We recommend running it on a small batch first to verify the results before processing your full inventory.
