If you collect order gift messages in your Shopify store that you would like to pass to your courier or use in your integrated label templates, Shiptheory offers two options to support this.
Use Order Notes
Any messages in the Order Notes section will be downloaded as a gift message:
Use a Custom Order Note
If you use an app that adds support for gift messages, it's likely that the app stores order gift messages in a custom order note. In this case, the app should either specify the name of the custom order note field it uses or you will have specified this in the app setup.
Enter the name of the custom order note field into the Custom Attribute Name in Shiptheory and click Save.
Should you have any further questions, please get in contact with the Shiptheory support team who will be happy to help!
