Couldn't build the extension for Zoho Desk which pushes new replies from the client to inside the ticket/thread.

Hello, I’ve been trying to build this function/extension based in this link

I need to add news threads/replys from the client to my ticket using this extension, but I’m not being successful while building the api:
__

headers = {"Content-Type":"application/json"};

data = {"test":"testing"};

response = invokeurl
[
type :POST
parameters:data
headers:headers
];

__
I couldn’t find what is the “installationId in the documentation, neither could understand properly what where do I put the synch_thread_object. I know thread submodule is an array of objects because of the the getRelatedRecords function.
__

{
  "data":{
    "threads":[
        {
            "extId":"SMa8974b1b935d957ffd9",
            "extParentId":"+123456789",
            "createdTime":"2018-09-10T11:54:03.000Z",
            "content":"What surprised",
            "direction":"in",
            "from":"+00032882",
            "to":["+00000273637"],
            "canReply":true,
            "extra": #SYNC_EXTRA_OBJECT,
            "actor": #SYNC_ACTOR_OBJECT
        }
         }
}


Could someone give me an example of a deluge function which add an thread/reply to the ticket, this is the ticket Id, for example 274334000008420097.

Thanks in advance.
