Iam getting wrong data from backend for product variants and fulfillment options on a web page

Retired Boards Appdev Fulfillment Api

Topic summary

A developer is encountering data discrepancies when retrieving product variant quantities and fulfillment options from the backend API.

Issue Details:

  • Backend quantity data doesn’t match what’s displayed on the frontend
  • The implementation uses metafields to store inventory quantities rather than Shopify’s native inventory system
  • Data appears incorrect when showing quantities across different locations

Suggested Troubleshooting:

  • Verify whether data is syncing correctly to the metafield
  • Consider using Shopify’s built-in inventory_quantity property on the variant object instead of custom metafields
  • Confirm the data source and synchronization process for multi-location inventory

Current Status:
The issue remains unresolved, with the developer confirming they need to display quantities to users across different locations but the data is showing incorrectly.

Hi there :waving_hand:

Is there a reason you are using an inventory quantity on a metafield opposed to the inventory quantity on the variant itself?

Have you confirmed that the data is getting synced correctly to the metafield?
