Live Data Feed

Hi,

I was wondering if anyone could help me? I have set up an online store but I also sell some products which I dropship. I would like to somehow create a live stock update from the drop shipping company. They have supplied me with a live data feed address but how can I get to my shop to update stock levels for their products?

I have been searching all over the Internet and have not been able to find the answer. I’m hoping someone here will shed some light on to this. Thank you in advance.
