How can I retrieve an order that has a specific value set in an additional order info key?
Litium version: 6.2.0
You can search for your additional order info value:
var tagName = Litium.Foundation.Modules.ECommerce.Search.TagNames.GetTagNameForAdditionalOrderInfo("MyAdditionalOrderInfo");
query.FilterTags.Add(new Tag(tagName, "Value to search for"));
