Local $bSuccess = False

; This example assumes the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.

; The previously fetched eBay access token looks like this:

; {
;   "access_token": "v^1.1#i^1# ... HwSAAA=",
;   "expires_in": 7200,
;   "refresh_token": "v^1.1#i^1# ... FXjEyODQ=",
;   "refresh_token_expires_in": 47304000,
;   "token_type": "User Access Token"
; }
