Amazon MWS - Update inventory product quantity?

Question

I recently got into using the Amazon AWS but it looks quite weird to me. I thus far managed to get orders etc.

For a customer, he wants his private web store products to be synced with amazon. I'm aware that you can simply upload a .csv of the product inventory which we did.

Is there any way using the MWS (in php) to update the quantity? I'd preferably let a cron run every xxx hours to update the quantity at amazon as the stock may decrease if someone purchases anything outside amazon.

Couldn't really find anything relevant thus far, nor in the amazon nws scratchpad.

Thanks!

We do this basically by uploading a stripped down CSV file that only contains the SKU and the new quantity (among with two or three other fields that are required).

You need to submit a feed to Amazon of type _POST_FLAT_FILE_LISTINGS_DATA_.
