Posting web page to API

Hi all,

I need to send SMS to the users in my web site (VS 2008,SQL 2005). So we bought a API from a vendor. I need to post some XML content to it in order to send the SMS.

I was able send SMS successfully by post method.

 Problem1:

 Now my problem is after clicking on a button 1st  need to save some data in my database and then I need to post the page to the API.

Please suggest me how to do it.

 Problem2:

I have one more problem here. After sending SMS the API is giving some XML Content back to me by which I can track SMS Status (Sent or failed.). So after sending SMS that external page(XML Content) is displayed instead of my web site . Please suggest me how to avoid it.

Thanks,

Subbu
