require 'chilkat'

# Note: Requires Chilkat v9.5.0.64 or greater.

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

# Load our previously obtained access token. (see PayPal OAuth2 Access Token)

# Build the Authorization request header field value.

# Make the initial connection.
# A single REST object, once connected, can be used for many PayPal REST API calls.
# The auto-reconnect indicates that if the already-established HTTPS connection is closed,
# then it will be automatically re-established as needed.

# ----------------------------------------------------------------------------------------------
# The code above this comment could be placed inside a function/subroutine within the application
