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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

loHttp.BasicAuth = 1
loHttp.Login = "API_USERNAME"
loHttp.Password = "API_PASSWORD"

* Build and send the following JSON:

* The "retref" is the value returned in the JSON response for the Authorization request.

* {
*     "retref":"112989260941",
*     "merchid":"MERCHANT_ID"
* }

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateString("retref","112989260941")
loJson.UpdateString("merchid","MERCHANT_ID")

lcUrl = "https://<site>.cardconnect.com:<port>/cardconnect/rest/void"
lcResponseStr = loHttp.PutText(lcUrl,loJson.Emit(),"utf-8","application/json",0,0)
IF (loHttp.LastMethodSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loJson
    CANCEL
ENDIF

* A response status of 200 indicates potential success.  The JSON response body
* must be examined to determine if it was truly successful or an error.
? "response status code = " + STR(loHttp.LastStatus)

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJsonResp = CreateObject('Chilkat.JsonObject')
loJsonResp.Load(lcResponseStr)
loJsonResp.EmitCompact = 0

? "response JSON:"
? loJsonResp.Emit()

* A successful response looks like this:

* {
*   "authcode": "REVERS",
*   "respproc": "FNOR",
*   "amount": "0.00",
*   "resptext": "Approval",
*   "currency": "USD",
*   "retref": "112989260941",
*   "respstat": "A",
*   "respcode": "00",
*   "merchid": "496160873888"
* }
