-- See Global Unlock Sample for sample code.

-- Gets detailed order item information for a specified order ID
-- The order ID is something like "902-1845936-5435065" and it is the AmazonOrderId returned in the JSON when getting the list of orders.  For example:

-- Now that we have the RDT, we can use it to get information about the order.
--
-- Yes, the SP-API is horribly tedious and painful.  You must use an RDT specifically tailored to each request requiring an RDT,
-- the RDT must not be over an hour old, and if you need to get a new RDT you must get it using an LWA token that itself is not
-- more than an hour old.  If the LWA is more than an hour old, you must get a new one.  Ughhh!!!!!
-- ------------------------------------------------------------------------------------------------------------

-- Disconnect from the non-sandbox domain.  This example will use the sandbox.
-- (The RDT was obtained using the non-sandbox domain.  For some reason, the sandbox domain does not work for getting the RDT.)
