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

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

* The access token JSON looks like this:

* {
*   "access_token": "ey....",
*   "expires_in": 300,
*   "id_token": "ey....",
*   "not-before-policy": 0,
*   "refresh_expires_in": 1800,
*   "refresh_token": "ey...",
*   "session_state": "...",
*   "token_type": "bearer"
* }

loHttp = CreateObject('Chilkat.Http')

* Implements the following CURL command:

* curl -X "POST" "https://idp.comprobanteselectronicos.go.cr/auth/realms/rut-stag/protocol/openid-connect/token" \
*  -H "Content-Type: application/x-www-form-urlencoded; charset=utf-8" \
