[SalesForce] Exact Target Triggered Send using REST API, include CC and BCC Addresses

You can do this using the sendBatch method. Let me know if this works for you.

   {
      "From":{
         "Address":"code@exacttarget.com",
         "Name":"Code@"
      },
      "To":{
         "Address":"example1@example.com",
         "SubscriberKey":"example1@example.com",
         "ContactAttributes":{
            "SubscriberAttributes":{
               "Region":"West",
               "City":"Indianapolis",
               "State":"IN"
            }
         }
      }
   },
   {
      "From":{
         "Address":"code@exacttarget.com",
         "Name":"Code@"
      },
      "To":{
         "Address":"example2@example.com",
         "SubscriberKey":"example2@example.com",
         "ContactAttributes":{
            "SubscriberAttributes":{
               "Region":"East",
               "City":"Columbus",
               "State":"OH"
            }
         }
      }
   }
]

The REST call to send a triggered message does not provide the ability to update a data extension. It does allow you to update "send time attributes' for a subscriber, and those are passed in as the to: section of the payload:

  "To":{
     "Address":"example1@example.com",
     "SubscriberKey":"example1@example.com",
     "ContactAttributes":{
        "SubscriberAttributes":{
           "Region":"West", //passed in at send time
           "City":"Indianapolis", //passed in at send time
           "Substitute_var1":"Value" //passed in at send time
        }
     }
  }

These attributes for the subscriber will need to be created prior to sending.
