The Update Shopify inventory when a Convictional product's inventory changes workflow on the FlowMattic canvas, with 3 steps across Convictional, Shopify — The workflow as it appears in the builder after import. Each step opens for editing.

What this workflow does

Retailers who drop-ship through Convictional depend on their sellers' stock counts. If those counts change and the Shopify store doesn't follow, customers can order items that are no longer available. This workflow passes each inventory change from Convictional to the matching product in your Shopify store.

The Convictional trigger fires when a seller updates the inventory quantity of a product variant. The event carries the variant's details and its new quantity; a test run shows exactly which fields arrive.

Next, the Shopify Search Product step looks up the product in your store by title or other criteria. It ships unmapped, so map a value both systems share, such as the product title or SKU, from the Convictional data. The final Update Inventory step then sets the inventory level for the variant it finds. Map the variant or inventory details returned by the search, and the new quantity from Convictional, into it.

Matching only works when the product exists in both places with the same identifying value. Test with one product you know is in both systems and check Task History to confirm the right variant changed before you rely on it for your whole catalogue.

Drop-ship store kept in step

A home goods retailer selling a supplier's range through Convictional sees Shopify stock drop as soon as the supplier records lower counts.

Restocks visible right away

When a seller adds new units of a sold-out variant in Convictional, the Shopify product gets the higher quantity and can be bought again.

Several sellers, one storefront

A marketplace-style Shopify shop with products from many Convictional sellers keeps every variant's stock in line without manual imports.

After importing, map your own data. To keep the template universal, not every step is pre-filled. Open each step in the builder and connect your accounts and fields (channels, lists, sheets, recipients) before you switch the workflow on.

Make it yours

Changes worth making after you import it.

Use SKUs that match exactly in Convictional and Shopify, so the Search Product step finds one clear product for each change.
Put a Filter between the Search Product step and the Update Inventory step that continues only when the search returned a product, so changes for items you don't stock stop there.
If a Shopify product has several variants, check in a test run that the search result lets you map the specific variant that changed, not just the first one.
If your store has more than one location, check in a test run which location the Update Inventory step changes, and set it to the one that holds drop-ship stock.

Questions about this workflow

How does the workflow know which Shopify product matches the Convictional item?

Through the Search Product step. You map a shared value, such as the title or SKU, from the Convictional event into the search, and the inventory update uses what it finds.

What if the Convictional product isn't in my Shopify store?

The search finds nothing to update and Shopify may return an error at the Update Inventory step. Open Task History to see the search result and Shopify's reply.

Does this workflow sync Shopify stock back to Convictional?

No. It works one way: seller inventory changes in Convictional update Shopify.

Does Shopify order activity start this workflow?

No. Only inventory changes that a seller records in Convictional start a run.
