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

* First get our previously obtained OAuth2 access token.
* 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")

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

* Connect to the REST server.
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("sandbox-quickbooks.api.intuit.com",lnPort,lnBTls,lnBAutoReconnect)

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbAuth = CreateObject('Chilkat.StringBuilder')
loSbAuth.Append("Bearer ")
loSbAuth.Append(loJsonToken.StringOf("access_token"))
loRest.Authorization = loSbAuth.GetAsString()

* --------------------------------------------------------------------------
* Note: The above code to setup the initial REST connection
* can be done once.  After connecting, any number of REST calls can be made.
* If the connection is lost, the next REST method call will automatically
* reconnect if needed.
* --------------------------------------------------------------------------

* Create the following JSON:

* {
*   "SyncToken": "3",
*   "Id": "33"
* }
*

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJsonReq = CreateObject('Chilkat.JsonObject')
loJsonReq.UpdateString("SyncToken","3")
loJsonReq.UpdateString("Id","33")

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbRequestBody = CreateObject('Chilkat.StringBuilder')
loJsonReq.EmitSb(loSbRequestBody)

loRest.AddHeader("Content-Type","application/json")
loRest.AddHeader("Accept","application/json")
loRest.AllowHeaderFolding = 0

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbResponseBody = CreateObject('Chilkat.StringBuilder')
lnSuccess = loRest.FullRequestSb("POST","/v3/company/<realmID>/invoice?operation=delete",loSbRequestBody,loSbResponseBody)

* Success is indicated by a 200 response status code.
? "response status code = " + STR(lnRespStatusCode)

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJsonResponse = CreateObject('Chilkat.JsonObject')
loJsonResponse.LoadSb(loSbResponseBody)
loJsonResponse.EmitCompact = 0
