* 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)
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.
loRest = CreateObject('Chilkat_9_5_0.Rest')
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("api.sandbox.paypal.com",443,1,lnBAutoReconnect)

* ----------------------------------------------------------------------------------------------
* 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..
* ----------------------------------------------------------------------------------------------

* Clear the REST object of any headers or query params from previous requests.
loRest.ClearAllHeaders()
loRest.ClearAllQueryParams()

loRest.AddHeader("Authorization",loSbAuth.GetAsString())

* The payment ID is added to the path.

loSbPath.Append("/v1/payments/payment/payment_id")
lnNumReplaced = loSbPath.Replace("payment_id","PAY-2CY489250W145633HLA3DK3Y")

* Send the GET request and get the JSON response.
