require 'chilkat'

# Note: Requires Chilkat v9.5.0.65 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)

# 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
# because the connection does not need to be made for every request.  Once the connection is made
# the app may send many requests..

# To capture payment, make a call to /v1/payments/authorization/[authorization_id]/capture with the authorization ID in the URI.
# See PayPal Authorize Payment for sample code to create the authorization.
# The "7X8332687A4929542" comes from the "transactions[0].related_resources[0].authorization.id" part of the authorization response.
