How to delete an order's Additional details?

Topic summary

Issue: Order “Additional details” (Shopify order customAttributes) are imported by Linnworks like customer Notes, cluttering printed paperwork. The goal is to auto-remove these details.

Solution implemented: A contributor showed that clearing order customAttributes (setting them to an empty array via Shopify Flow/API) removes Additional details. OP confirmed it works broadly.

Cautions/alternatives: Back up attributes to a metafield before deletion in case they’re needed later. Verify no processes/compliance depend on this data. Explore Linnworks print template customization or middleware to strip fields after ERP export but before printing. Push ERP/vendor for better controls.

New complication: The Flow isn’t removing the Klarna-related Additional detail (e.g., “Klarna Order ID”). OP tried duplicating the workflow and filtering by value (“Klarna”/“Klarna Order ID”) without success.

Media: Screenshots show the Flow action that empties customAttributes and the Klarna attribute that persists.

Status: Partially resolved. General orders are fixed; Klarna-specific entries remain. No confirmed workaround yet; paid help was offered. Discussion remains open.
