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

// curl -X POST \
//   https://www.wix.com/oauth/access \
//   -H 'Content-Type: application/json' \

//     "grant_type": "refresh_token",
//     "client_id": <CLIENT_ID>,
//     "client_secret": <CLIENT_SECRET>,
//     "refresh_token": <REFRESH_TOKEN>

// It is assumed we previously obtained an OAuth2 access token.
// This example loads the JSON access token file 
// saved by this example: Get WiX OAuth2 Access Token
