* 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.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJsonToken = CreateObject('Chilkat.JsonObject')
lnSuccess = loJsonToken.LoadFile("qa_data/tokens/qb-access-token.json")
IF (lnSuccess <> 1) THEN
    ? "Failed to load qb-access-token.json"
    RELEASE loJsonToken
    CANCEL
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}"
* }

loHttp.BasicAuth = 1
loHttp.Login = "QUICKBOOKS-CLIENT-ID"

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')

loJson.UpdateString("token",loJsonToken.StringOf("access_token"))
