I am using Classic ASP and trying to use the JustGiving API.
I\'d like to use it to display the total amount raised, and total donations received on my donation page
Try
http.Open "GET", vurl, False, "yourusername", "yourpassword"
I don't know if this works on justgiving, but it does with the Bing API
Also, this question may be relevant XmlHttp Request Basic Authentication Issue
Edit - using Response.ContentType and Msxml2.ServerXMLHTTP.6.0
vurl = "https://api.justgiving.com/API_KEY/v1/account"
Set http = Server.CreateObject("msxml2.ServerXMLHTTP.6.0")
http.Open "GET", vurl, False, "username", "pwd"
http.setTimeouts 5000, 5000, 10000, 10000 'ms - resolve, connect, send, receive'
http.setRequestHeader "Authorization", "Basic MY_AUTH_STRING"
http.Send
Response.ContentType = "application/xml"
Set items = http.responseXML.getElementsByTagName("account")
etc
