Hi,

I have already some time a commerce request to be able to change prices of my products using webservices.
Is there already a service which makes it possible to change the price of a product by a webservice as this?

Call Content:
<?xml version="1.0" encoding="utf-8"?>
<PRICELIST_REQUEST>
<CUSTOMER_NUMBER> XXXX</CUSTOMER_NUMBER>
<LOGIN>**** YOUR WEBSHOP LOGIN ****</LOGIN>
<PASSWORD> **** YOUR WEBSHOP PASSWORD ****</PASSWORD>
<TIMESTAMP>20110210103215</TIMESTAMP>
</PRICELIST_REQUEST>

And URL to make the call: 

www.example.com/b2b.main/create_order_xml

Which gives back first status ok, and then the price information per article which should be changed throughout the shop.
The information returned is:

<PRODUCT>
<PRODUCT_NUMBER>IT2976-04</PRODUCT_NUMBER>
<PRODUCT_ID>10147676</PRODUCT_ID>
<PRICE>300,00</PRICE>
<VALID_TO_DATE>20120131</VALID_TO_DATE>
<SCALES/>
</PRODUCT>

I think this is a very general question, because I see it happening in different shops, that the prices of the suppliers change per day/week/month.
Could if there is not such a service there, somebody give me a hand how to make this service?

Thanks a lot for your reply in advance!
