bool success = false;

// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// If SharePoint Windows classic authentication is used, then set the 
// Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = "SHAREPOINT_USERNAME";
http.Password = "SHAREPOINT_PASSWORD";
http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN";
http.NtlmAuth = true;

// The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
// If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
// establish the cookie as shown at SharePoint Online Authentication

// Indicate that we want a JSON reply

// Only persons who have Full Control or Design permissions can approve or reject
// items or files in a list or library that requires approval. Other site users
// can only view what they have permission to view or what they have uploaded
// themselves.
// 
// Important:  Approval or rejection of items or files in lists or libraries must
// be done one at a time. You cannot approve or reject multiple items or files in
// one operation.
