## Get a comment by ID

### Summary

Get comment details by comment id.

GET /api/v11/comments/<id>

### Description

Get comment details by comment id if the user has permission to view it. If the comment is a reply, the parent comment id is also returned.

- Private projects: when a project is made private, only the project owners, moderators, and members, plus users with super-level privileges in the P4 Server, can see the project, its activity streams, and ongoing reviews. API responses honor these private project restrictions. For more information about private project restrictions, see Private projects.
- Permissions: if a public review contains files that the user does not have permission to view, the review is returned but the restricted files are not displayed.

## Add a comment with an attachment to a review

### Summary

Add a comment with an attachment to a review.

POST /api/v11/comments/reviews/{id}

### Description

Add a comment with an attachment to a review. This is a two-step process:

1. Create a stand-alone attachment.

   Once the attachment is created, P4 Code Review assigns a unique id to the attachment. The unique attachment id is returned in the response. See Create an attachment.

2. Pass the unique attachment id as a parameter using the POST /api/v11/comments/reviews/{id} API endpoint.

   You have now successfully added a comment with an attachment to a review.

### Parameters

Parameter | Description | Type | Parameter Type | Required
--- | --- | --- | --- | ---
id | Review ID. | integer | path | Yes
body | The text content of the comment. | string | form | Yes
taskState | Optional task state of the comment. Valid values when adding a comment are comment (default) and open. This creates a plain comment or opens a task, respectively. If the taskState parameter is not in the request, the task state is set to comment. | string | form | No
notify | Comment notifications can be delayed, see Comment notification delay. The notify parameter enables you to set when the notification for the comment is sent. Valid options are: delayed (default): notifications for this comment are delayed by the time set in Comment notification delay immediate: the notification for this comment is sent immediately silent: no notification is sent for this comment | string | query | No
context | Used to add the comment to a file in the review. Valid fields are: file mandatory unless attribute or comment are set: File to comment on. Valid only for `changes` and `reviews` topics. For example, `//depot/main/README.txt`. type: the filetype of the file, text, binary, symlink, unicode, utf8, utf16, apple, or resource. For more information on filetypes, see the Base filetypes section of the P4 CLI Reference. version optional, integer: With a `reviews` topic, this field specifies which version to attach the comment to. leftline optional, but if specified, you must also specify the rightline and content parameters. Integer: Left-side diff line number to attach the inline comment to. Valid only for `changes` and `reviews` topics. rightline optional, but if specified, you must also specify the leftline and content parameters. Integer: Right-side diff line number to attach the inline comment to. Valid only for `changes` and `reviews` topics. content optional, but if specified, you must also specify the leftline and rightline parameters. Array of strings: Provide the content of the codeline the comment is on and the four preceding codelines. This is used to specify a short excerpt of context in case the lines being commented on change during the review. When set to null, P4 Code Review makes an effort to build the content on its own. Because this involves file operations, it might be slow. | array | form | No
attachments | Attachment id generated using the Create an attachment API endpoint. | integer | form | Yes

### Example usage

Create a comment with attachment id 12, make the comment an open task, and delay sending the comment notification:

curl -X POST -H "Content-Type: application/json" -u "username:ticket" -d "@mybodyfilename.txt" "https://my-swarm-host/api/v11/comments/reviews/885"

The "mybodyfilename.txt" file contains the authenticated user's comment, the attachment id 12, and makes the comment an open task:

    {
      "body": "This is another comment.",
      "taskState": "open"
      "context" : {
        "file": "//depot/Jam/MAIN/src/jamgram.c",
