I'm really green in this subject and don't really know who I could ask to help me.

What I need is as followed:

Supplier 1 has a system which confirms to a standard called STOSAG.

Supplier 1 can put the data in a webservice (XML).

I need to provide the webservice where he can put his data in.

I need to automatticly download the data and put it into Zoho. 

My questions:

1. How do I make a webservice? 

2. How can I automatticly download the data into Zoho?

Hope someone can help me.

Greatings,

Erwin
