# 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)

# 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
# because the connection does not need to be made for every request.  Once the connection is made

# 	  "amount": {
