* 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.
loJsonToken = CreateObject('Chilkat.JsonObject')
lnSuccess = loJsonToken.LoadFile("qa_data/tokens/qb-access-token.json")

loRest = CreateObject('Chilkat.Rest')

* Connect to the REST server.

* --------------------------------------------------------------------------
* 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:

* {
