question

yea, I had to get it from financial transactions. But there's no way (I know of) to tie it to an order. Not sure how we're supposed to calculate SKU level margins with this API.

Has anyone else contacted premium support maybe regarding this issue? This is super annoying.

I also needed to get the shipping cost paid by seller and could not find any way to get it reliably. The Transactions API will return shipping labels purchased, but it will only have an 'order_id' field populated if the label is USPS (???). Any labels bought with the bulk label function will show up as one transaction with no 'order_id'. The Transactions report CSV mirrors this behavior.

I asked Premium Support about this and they acknowledged there's no way to get it. They said they considered adding support for it, but decided not to. :(

Looks like we're on our own. I only need this for my own personal purposes, so I plan on building a web scraper that just scrapes the order details page (which has the shipping paid). But obviously this wouldn't work for apps intended for third party sellers.

Wow, that decision makes absolutely no sense. How do they expect people to reconcile their shipping cost payments? I see getTransactions shows me the FedEx/UPS shipping amount I paid, which is nice and everything, but USPS is entirely missing and is 90% of my shipments. It seems that PayPal, which I think is where most of us buy our postage through, doesn't provide any type of eBay Order ID either to reference. I think they used to but I don't recall seeing it lately. Even the tracking number appears to be gone from PayPal reporting and would have been a good common field between the two datasets. Can you respond back to them that there's a big demand for this info and it's baffling how they wouldn't include something like this? It's pretty critical information, they have a million other useless API endpoints for all kinds of things but leave out this one massive thing that impacts everyone.
