Getting comment id when posting a transition with comment through Jira Rest API

[Jean-François FORGET]

Hi folks,

I can't find any information about that so i try here.

With Jira API, i can post a comment trough the following API url:

https://my.jira.instance/rest/api/2/issue/<issue key>/comment

With the following body:

{  
   "body":"My single comment"
}

Then i get an answer with the ID of my new comment: (there is the 394380)

 {  
   "self":"https://my.jira.instance/rest/api/2/issue/208609/comment/394380",
   "id":"394380",
   "author":{  
       author details
   },
   "body":"My single comment",
   "updateAuthor":{  
      author details
   },
   "created":"2018-06-18T14:59:41.246+0200",
   "updated":"2018-06-18T14:59:41.246+0200"
}

BUT, when i want to apply a transition WITH a comment through this API url:

https://my.jira.instance/rest/api/2/issue/<issue key>/transitions?expand=transitions.fields

And with this body:

{  
   "update":{  
      "comment":[  
         {  
            "add":{  
               "body":"My comment on transition"
            }
         }
      ]
   },
   "transition":{  
      "id":"241"
   }
} 

then i get no answer body. Only the answer status: 204 No content

I need to get the comment ID.

My current workaround are:

- Make a new call to get the last comment ID after the transition + comment

- Make the single comment, then make the transition call

But I'm not very happy with that.

Any help would be appreciate. Do i miss something or is it a feature that is missing in the Jira API ?

Hi @Jean-François FORGET

I am afraid that the REST API endpoint that performs transitions, POST /rest/api/2/issue/{issueIdOrKey}/transitions is not actually expected to provide any other REST response other than the HTTP 204 code for a successful transition.  From that page:

Responses

• STATUS 400
  If there is no transition specified.

• STATUS 204
  Returned if the transition was successful.

• STATUS 404
  The issue does not exist or the user does not have permission to view it

So although you can add comments during a transition, there has not been the expectation that the REST API would return to you the ID of that comment in that situation.

I understand if either your work-around are less than desirable, however when searching through the JRASERVER project on JAC I have not yet found another other previous requests for this particular functionality out of the transition REST response.  

If you like you could create a new suggestion issue in that project.   I would also recommend checking out the Implementation of New Features Policy.   I can't guarantee that this feature might be implemented some day, but providing a use case and an explanation of why this would be helpful to have can then at least serve as a place where other users can watch and vote on such a request.
