<?php

//  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)

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

//  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.
