ReviseFixedPriceItem on 4000 items several times a day?
So I have roughly 4,000 items on eBay that I also sell on other Marketplaces and my own website of course. I want to sync the quantities 2 or 3 times a day. Is ReviseFixedPriceItem the best way to go? Run that API several times a day to update quantities of every item? And the docs for that API say that I must include Shipping Details so as not to lose that setting in each call (which makes zero sense... why just THAT setting will get lost?). That means I first need to GET the shipping details. So I do a call for EACH ITEM to get the Shipping details, then another call for EACH item to update the quantity... 4,000 times several times a day? That doesn't seem right.
Or is better to GET the shipping details AND quantity of each item, and then only update if the quantity is different than what my database on my website says? Or is there a better way to do this that I'm missing?
