* 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)
loJsonToken = CreateObject('Chilkat_9_5_0.JsonObject')
loJsonToken.LoadFile("qa_data/tokens/paypal.json")

* Build the Authorization request header field value.
loSbAuth = CreateObject('Chilkat_9_5_0.StringBuilder')
* token_type should be "Bearer"
loSbAuth.Append(loJsonToken.StringOf("token_type"))
loSbAuth.Append(" ")
loSbAuth.Append(loJsonToken.StringOf("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..
