(AutoIt) PayPal - Capture Authorization

Capture and process a previously created authorization. The original payment call must have the intent set to authorize.

Note: This example requires Chilkat v9.5.0.65 or greater.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

; 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)
$oJsonToken = ObjCreate("Chilkat.JsonObject")
$oJsonToken.LoadFile("qa_data/tokens/paypal.json")

; Build the Authorization request header field value.
$oSbAuth = ObjCreate("Chilkat.StringBuilder")
; token_type should be "Bearer"
$oSbAuth.Append($oJsonToken.StringOf("token_type"))
$oSbAuth.Append(" ")
$oSbAuth.Append($oJsonToken.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.
$oRest = ObjCreate("Chilkat.Rest")
Local $bAutoReconnect = True
Local $bSuccess = $oRest.Connect("api.sandbox.paypal.com",443,True,$bAutoReconnect)
If ($bSuccess <> True) Then
    ConsoleWrite($oRest.LastErrorText & @CRLF)
    Exit
EndIf

; ----------------------------------------------------------------------------------------------
; 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 a particular amount, build JSON such as this:
$oJson = ObjCreate("Chilkat.JsonObject")
$oJson.EmitCompact = False
$oJson.UpdateString("amount.currency","USD")
$oJson.UpdateString("amount.total","6.70")
; is_final_capture is optional and indicates whether to release all remaining funds that the authorization holds in the funding instrument.
$oJson.UpdateBool("is_final_capture",True)
ConsoleWrite($oJson.Emit() & @CRLF)

; The JSON created by the above code:

; 	{ 
; 	  "amount": { 
; 	    "currency": "USD",
; 	    "total": "6.70"
; 	  },
; 	  "is_final_capture": true
; 	}

; This is the OAuth2 Authorization header, not to be confused with a PayPal credit card authorization...
$oRest.AddHeader("Authorization",$oSbAuth.GetAsString())
$oRest.AddHeader("Content-Type","application/json")

; The authorization ID is added to the path.
; The authorization ID is obtained from payment records as shown here: Find Authorizations
$oSbPath = ObjCreate("Chilkat.StringBuilder")
$oSbPath.Append("/v1/payments/authorization/authorization_id/capture")
