# The following comments apply to SharePoint Windows classic authentication.
# -------------------------------------------------------------------------
# For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
# The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
# The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"
# Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
# for example, "chilkat" instead of "chilkat@mycompany.com"

$http = New-Object Chilkat.Http

# 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

# The contents of a SharePoint list can be downloaded by it's URI,
# which has the following URL format:
# https://xyzoffice.mycompany.com/_api/Web/Lists(guid'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx')/items
# 
# To get the URI's for all SharePoint lists, 
# See Get SharePoint Lists.

# Download the list like this (where the SHAREPOINT_DOCUMENTS_GUID is replaced with the actual GUID)
$sbJson = New-Object Chilkat.StringBuilder
$success = $http.QuickGetSb("https://SHAREPOINT_HTTPS_DOMAIN/_api/Web/Lists(guid'SHAREPOINT_DOCUMENTS_GUID')/items",$sbJson)

    $json.I = $i

    $title = $json.StringOf("d.results[i].Title")

# My output when testing is like what is shown below.

# I found that not every item has a Title,  but as viewed in a browser, I can see each of the item's name.
# (The number of items agrees with what I can interactively see in a browser.) The mystery of what
# is being shown for the name (or title) in the browser will be investigated further as Chilkat
# continues to explore the SharePoint API...
