Use VBA to track parcels from USPS API

New Contributor

Does anyone have a module to get status and info for parcels from USPS API ?
I have created the code below, but I don't know how to get the right response :

Dim html As HTMLDocument, dateString As String
Set html = New HTMLDocument

With CreateObject("MSXML2.XMLHTTP")
.Open "GET", "http://secure.shippingapis.com/ShippingAPI.dll?API=TrackV2&XML=<TrackRequest USERID=" & "988HONES7813" & "><TrackID ID=" & id & "></TrackID></TrackRequest>"
.send
GetRESPONSE = .responseText

Could you try this function?

Public Function TestTrackRequest()
Dim oXML As Object
Dim oDOM As Object
Dim sHTML As String

Set oXML = CreateObject("MSXML2.XMLHTTP")
Set oDOM = CreateObject("MSXML2.DOMDocument.6.0")

With oXML

sHTML = "http://production.shippingapis.com/ShippingAPI.dll?API=TrackV2&XML=<TrackRequest USERID='988HONES7813'><TrackID ID='EJ958083578US'></TrackID></TrackRequest>"

.Open "GET", sHTML, False

.send sHTML

If .Status = "200" And .responseXML.childnodes.length > 0 Then
oDOM.loadxml (.responseText)

If oDOM.childnodes(1).tagname = "Error" Then
Debug.Print oDOM.childnodes(1).childnodes(0).Text & " - " & oDOM.childnodes(1).childnodes(1).Text
Else
Debug.Print oDOM.XML
End If
Else
Debug.Print .Status & " - " & .responseText
End If

End With

Set oXML = Nothing
Set oDOM = Nothing

End Function

I think that it works. I get an error '80040B1A - API Authorization failure' but it seems that the userID is not valid. I'll let you know if it works when I solve the error. Thank you

Thank you. I will.
