How do I detect if the order/create payload contains items that were bundled?

[AV_SL]

The order/create webhook payload doesn't seem to contain the lineItemGroups object in the lineItem data.

Is there an undocumented way to subscribe to this data?

Or is there another way to detect if an order contains line items that belong to a group / bundle?

It doesn't seem very efficient to receive the webhook, then make a call back to Shopify to get the order object with the lineItemGroups data.

Any pointers are much appreciated.

Thanks,

Anthony
