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

loHttp = CreateObject('Chilkat.Http')

* Implements the following CURL command:

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

* Get the "refresh_token"
lcRefreshToken = loJsonToken.StringOf("refresh_token")

* The following JSON is sent in the request body.

* {
*   "grant_type": "refresh_token",
*   "client_id": <APP_ID>,
*   "client_secret": <APP_SECRET>,
*   "refresh_token": <REFRESH_TOKEN>
