Here is what we are planning to do

1. Give a UI on the app to create a ticket

2. Show the ticket status on the app

3. Show the comments by the agent on the app

4. Allow customer to respond to the agent comments

5. If ticket is closed, allow customer to reopen.

Now we are able to everything except for #4. Which API we need to use post comments on behalf of the user. 

Regards

Ajay

PS : SDK integration is out of scope for now.
