Providing authentication info via msxml2.ServerXMLHTTP - api

Question

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, on my website.
I can see that info is available via:
https://api.justgiving.com/docs/resources/v1/Account/Retrieve
<%
vurl = "http://api.justgiving.com/---myIDhere---/v1/account"
Set http = Server.CreateObject("msxml2.ServerXMLHTTP")
http.Open "GET", vurl, False
http.Send
Set dom = Server.CreateObject("msxml2.DOMDocument")
dom.loadXML http.responseText
Set items = dom.getElementsByTagName("account")
For Each item In items
Set var_totalDonated = item.getElementsByTagName("totalDonated")
If NOT (var_totalDonated IS Nothing) Then
var_totalDonated = ap(totalDonated(0).Text)
response.write var_totalDonated
End If
Next
%>
However, the page times out when I access it.
I think it's because I need to provide some authentication information as detailed here:
https://api.justgiving.com/docs/usage#protectedResources
So I got that authentication info.
But I have no idea how to "send" it to the API, so that it can authenticate me as a user and provide the info.
It also mentions providing info on the header via the link above this one (I can't post the link as I don't have enough reputation), but replace #protectedResources at the end of the URL with #contentTypes.
I'm sorry - am I also missing something on that side?
I'm sorry if I'm asking silly questions, but the info on the API docs assumes some level of intelligence on the part of the user, and I don't have a lot of it!
Any advice much appreciated.
Thanks
Thanks to John for your reply.
Based on that, I changed the code to:
<%
vurl = "https://api.justgiving.com/API_KEY/v1/account"
Set http = Server.CreateObject("msxml2.ServerXMLHTTP")
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
Set dom = Server.CreateObject("msxml2.DOMDocument")
dom.loadXML http.responseText
Set items = dom.getElementsByTagName("account")
For Each item In items
Set var_totalDonated = item.getElementsByTagName("totalDonated")
If NOT (var_totalDonated IS Nothing) Then
var_totalDonated = (var_totalDonated(0).Text)
response.write var_totalDonated
End If
Next
%>
But unfortunately the page still times out.
I'm checking also via:

But no answer so far.
Thanks again

End If

Previously I was using:
vurl = "https://api.justgiving.com/AP_KEY/v1/account"
But when I changed it to https it worked.
I thought I had tried that previously, but obviously not.
Thanks again to John, I really appreciate your help!

Answer 1

Try
http.Open "GET", vurl, False, "yourusername", "yourpassword"
I don't know if this works on justgiving, but it does with the Bing API

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

Answer 2

Apologies for adding to an old post. However this has consistently come up when Googling for help on MailChimp API V3.0 and VBA.
This is the fix I used:
ret = objhttp.Open("POST", sURL, False)
objhttp.setRequestHeader "Content-Type", "application/json"
objhttp.setRequestHeader "Accept", "application/json"
'V3 API uses HTTP Basic Authorisation inside an https: wrapper.
'The standard windows method does not seem to work however the
'following hack does.
'In summary the user name and APIkey are seperated with a Colon: and
'base 64 encoded and added to a Http RequestHeader
objhttp.setRequestHeader "Authorization", "Basic " & Base64Encode(APIUser & ":" & ApiKey)
objhttp.send (sJson)
You will need to code the Base64Encode function. I grabbed some code from http://pastie.org/1192157 (Ex StackOverflow) and pasted it into a VBA Module.
Hope it helps.
