Does logPurchase support item arrays with multiple objects?

[chipoglesby]

I have been able to successfully use logPurchase with a single item object that is sent to Firebase/GA4 for collection and analysis.

However, I am unsuccesful at sending an item array with multiple objects. I have been unable to find a solution online or in the documentation.

Any suggestions or help you may have would be greatly appreciated.

This works

item = {
  item_id "xxx_1",
  item_name: "xxx_1",
  Item_quantity: 2,
  index: 1,
  price: 12.99,
  item_category: "xxx",
};

This does not work

item = [item_1, item_2]

item_1 = {
  item_id "xxx_1",
  item_name: "xxx_1",
  Item_quantity: 2,
  index: 1,
  price: 12.99,
  item_category: "xxx"
};

item_2 = {
  item_id "xxx_2",
  item_name: "xxx_2",
  Item_quantity: 2,
  index: 2,
  price: 12.99,
  item_category: "xxx",
};

With apologies, I'm unsure - this hasn't come up before. Have you asked on stackoverflow with appropriate firebase tagging? The firebase team answers there, and if firebase-js-sdk can do it, and/or either of the native platforms, we should be able to

@mikehardy, I have, but I have not found a solution yet.

Firebase supports a parcelable array for items.

GA4 supports it as well.
