Shipment status in V3

[emergingdzns]

Hey folks. We've run into a small stumbling block with V3. In V2 we used to get a field (I think called major_tracking_state?) on the receipts that would give us shipping status on receipts. Now, in V3 it will list any shipments tied to the receipts but all it gives is the tracking code and carrier. There's no status on the shipments.

So, we are left with making several calls to the api using the logic below. I'm looking for opinions from others on if this makes sense to you. I've done it this way because it seems like the was_shipped and was_delivered being set to false don't equate to "show me the receipts where the items are NOT shipped or NOT delivered" but rather setting to false is like not including the filter at all.

1. Create an empty array to store receipt ids to ensure we don't classify one receipt in multiple states of shipping (call it $receipt_ids_found (we are using PHP).
2. Request receipts where was_shipped=true and was_delivered=true. Any receipts that come out from this query I think we can safely quantify as "Delivered". We then take the receipt ids from this result set and add them to the $receipt_ids_found array.
3. Request receipts where was_shipped=true and was_delivered=false. Filter out any where the receipt id is already in $receipt_ids_found. Then put these ids into the $receipt_ids_found array. I think we can count these as "In Transit". However, what if there are no records in the shipments array?
4. Request receipts where was_shipped=false and was_delivered=false. Again, filter out any where the receipt id is already in $receipt_ids_found. So at this point I think the best approach is to look for records in the shipments array. If there's at least one, we mark it as "In Transit". If there are none, we assume not yet shipped.

Unless I'm mistaken, a seller can mark and order as shipped without entering a carrier name or tracking number. So there's really no way to track the actual status.

If anyone has a better method for getting a more accurate status, it would be greatly appreciated.
