' This example does the following:

' curl -X GET https://yourInstance.salesforce.com/services/oauth2/userinfo \
'      -H "Authorization: Bearer YOUR_ACCESS_TOKEN"

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Http")
set http = Server.CreateObject("Chilkat.Http")

' Use the following online tool to generate HTTP code from a CURL command
' Convert a cURL Command to HTTP Source Code

' This example assumes the OAuth2 access token was previously fetched 
' and saved to a file.  See Get SalesForce OAuth2 Access Token via Authorization Flow

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
