How to use Channel integration

How to use Channel integration

I posted the question befire but I think this is different issue so I post this as a new question
I'm following this guide  https://www.zoho.com/desk/extensions/guide/

I want in use Channel integration feature with my API to create tickets.
Is it correct if I just want that feature only so I can do by using Resources.json alone without touching anything else?

My Resources.json is
{
"channel": {
"channelLogoPath" : "/app/img/logo.png",
"acceptAttachments" : false,
"updateRecords" : true,
"contentTypes" : [ "text/plain", "text/html"],
"redirectUrl" : "xxxxxxxxxxxxx",
"includeQuotedMessage": false,
"sync": {
"push": "xxxxxxxxxxxxxxxxxxx",
"pull": "xxxxxxxxxxxxxxxxxxx"
}
}
}
But I tried to test in devmode and prod seems like my extension didn't do anything

Did I miss something? And how can I debug this?
Please help.
