Demonstrates how to revoke a QuickBooks OAuth2 access token. Delphi DLL

//  See Global Unlock Sample for sample code.

//  This example assumes we previously obtained an OAuth2 access token for QuickBooks.

//  The access token JSON looks something like this:

//  {
//    "expires_in": 3600,
//    "x_refresh_token_expires_in": 8726400,
//    "refresh_token": "L011546037639r ... 3vR2DrbOmg0Sdagw",
//    "access_token": "eyJlbmMiOiJBMTI4Q0 ... oETJEMbeggg",
//    "token_type": "bearer"
//  }

//  This code sends the following request:

//  POST https://developer.api.intuit.com/v2/oauth2/tokens/revoke HTTP/1.1
//  Accept: application/json
//  Authorization: Basic UTM0dVB...wM1d2
//  Content-Type: application/json
