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

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

loJsonToken = createobject("CkJsonObject")

if (llSuccess <> .T.) then
    ? "Failed to load qb-access-token.json"
    release loJsonToken
    return
endif

// 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
// 
// {
//     "token": "{bearerToken or refreshToken}"
// }
