How to extract custom order metafields

Shopify Apps

Topic summary

A merchant is struggling to trigger email automations in Omnisend when customers purchase product bundles. They use Simple Bundles and Kits app, which breaks bundles into individual line items via Shopify’s Cart Transform API—beneficial for syncing with Zoho Inventory but problematic for automation triggers based on bundle SKUs.

Current Workaround Being Tested:

  • Simple Bundles now supports custom order metafields containing bundle names
  • Using Shopify Flow to automatically tag orders based on these metafields
  • Triggering Omnisend automations via order tags instead of SKUs

Challenges:

  • Timing issues: tags sometimes don’t apply quickly enough for Omnisend to detect immediately after order placement
  • Both Omnisend and Simple Bundles teams recommend adding a 5-minute delay to allow metafields to update
  • Merchant needs to differentiate between two bundle types for separate automations

The discussion remains ongoing as participants explore whether Shopify Flow can filter by specific bundle SKU information within metafields. Reverting to the older bundles app version (v1) would solve the automation issue but breaks critical inventory syncing with Zoho.

I’ve been testing a possible workaround for this. Since the bundles app can now add custom order metafields with the bundle name, I tried setting up a Shopify Flow to tag orders based on those metafields. Then I used that tag in Omnisend to trigger the automation instead of relying on the bundle SKU.

It’s not fully working yet—sometimes the tag doesn’t apply fast enough for Omnisend to pick it up right after the order comes through.
