'  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"
'  }

success = json.LoadFile("qa_data/tokens/ebay-access-token.json")

    Response.Write "<pre>" & Server.HTMLEncode( "Failed to load the existing ebay access token JSON.") & "</pre>"

'  Replace these with actual values.

'  Save the new JSON access token response to a file.
'  The access + refresh tokens contained in this JSON will be needed for the next refresh.
