bool success = false;

// This example does the following:

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

Chilkat.Http http = new 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

Chilkat.JsonObject json = new Chilkat.JsonObject();

// Here's an example of the JSON:

// {
//   "access_token": "00D41000....uLZBpT6",
//   "refresh_token": "5Aep....25xdGgkrV",
//   "signature": "cjTbSc5DvcKpaMoRTzuQTJLb1tcMw8LEO01flq4aMD4=",

//   "token_type": "Bearer",
//   "issued_at": "1738348388166"
// }

// Adds the "Authorization: Bearer YOUR_ACCESS_TOKEN" header.
http.AuthToken = json.StringOf("access_token");

// We want to build the following URL:  https://<instance_id>.salesforce.com/services/oauth2/userinfo
Chilkat.StringBuilder sbUrl = new Chilkat.StringBuilder();

// The expected JSON response is something like this:
