Orders / Delivery Notes

​
Add a requested delivery date

Orders with an _olx_delivery_date note attribute will be imported with the passed date set as the Delivery Date.
The date must be passed in the format Y-m-d, e.g. 2026-01-16. In case an invalid format is passed, ONELOX will ignore the requested delivery date and not reject fulfillment. This prevents third party Apps from blocking fulfillment due to malformed data.

​
Passing custom data

By default, ONELOX ignores all note attributes on an order unless prefixed with _olx_.
If you need ONELOX to process and transfer other note attributes, you may add the appropriate keys in the Shopify integration settings.
Note attributes are stored in the resulting Delivery Note’s additional attributes and transmitted to the Fulfiller, if supported by the target integration.

​
Products

​
Advanced master data configuration

Currently, Shopify does not provide options to configure a product’s full master data.
To make use of ONELOX’ fine grained product master data representation, you may add various data to your product variants directly in Shopify through metafields.

​
Available dimension metafields

  • length
  • width
  • height
ONELOX processes and converts values present in these fields if possible. These metafields may either be an Integer — in that case, ONELOX assumes the number directly corresponds to the product’s dimension in millimeters — or a Dimension type.
ONELOX will automatically convert a Dimension type value to millimeters for internal use.

​
Available storage configuration metafields

  • refrigerated
  • dangerous_goods
  • battery
  • fragile
  • batchable
  • perishable
  • has_serial_numbers
ONELOX processes and converts values present in these fields if possible. These metafields must be a True or false (Boolean) type.

​
Available advanced product data metafields

  • packaging_unit
ONELOX processes and converts values present in this field if possible. This metafield must be an Integer type.
Metafields that contain invalid data or do not match the recognized types in Shopify are ignored by ONELOX.
This prevents conflicts with other integrations or otherwise already defined metafields.
