Best API for updating large inventory stock/price

[morphtarget21]

We need a reliable API platform/call that would handle 5K+ items.

The objective is to update stock quantity and/or price for thousands of listings at a time every 24 hours.

I read documentation about "bulkUpdatePriceQuantity" but it says we can only update 25 items??

Is there a different way to maybe upload updates via an xml file? or a cron job that automatically check our xml file for changes?

Thanks

Seller Hub > Reports > Uploads  has a spreadsheet option to bulk edit price and quantity (formerly File Exchange). One spreadsheet can update all 5K items.

To automate the process, look at the Feed API:

• Add, revise, and end listings (FX_LISTING)    <-- FX refers to File Exchange

eBay's Large Merchant Services (LMS) feed could similarly revise price and quantity in bulk.
