Custom media types

Pull request review comments are comments on a portion of the unified diff made during a pull request review. Commit comments and issue comments are different from pull request review comments. You apply commit comments directly to a commit and you apply issue comments without referencing a portion of the unified diff. For more information, see "Create a commit comment" and "Create an issue comment."

Pull Request review comments use these custom media types. You can read more about the use of media types in the API here.

Multi-line comment summary

Note: New parameters and response fields are available for developers to preview. During the preview period, these response fields may change without advance notice. Please see the blog post for full details.

Use the comfort-fade preview header and the line parameter to show multi-line comment-supported fields in the response.

If you use the comfort-fade preview header, your response will show:

For multi-line comments, values for start_line, original_start_line, start_side, line, original_line, and side.
For single-line comments, values for line, original_line, and side and a null value for start_line, original_start_line, and start_side.

If you don't use the comfort-fade preview header, multi-line and single-line comments will appear the same way in the response with a single position attribute. Your response will show:

For multi-line comments, the last line of the comment range for the position attribute.
For single-line comments, the diff-positioned way of referencing comments for the position attribute. For more information, see position in the input parameters table.

Create a comment

Creates a review comment in the pull request diff. To add a regular comment to a pull request timeline, see "Comments." We recommend creating a review comment using line, side, and optionally start_line and start_side if your comment applies to more than one line in the pull request diff.

You can still create a review comment using the position parameter. When you use position, the line, side, start_line, and start_side parameters are not required. For more information, see Multi-line comment summary.

Note: The position value equals the number of lines down from the first "@@" hunk header in the file you want to add a comment. The line just below the "@@" line is position 1, the next line is position 2, and so on. The position in the diff continues to increase through lines of whitespace and additional hunks until the beginning of a new file.

POST /repos/:owner/:repo/pulls/:pull_number/comments

Parameters

Name	Type	Description
`body`	`string`	Required. The text of the review comment.
`commit_id`	`string`	Required. The SHA of the commit needing a comment. Not using the latest commit SHA may render your comment outdated if a subsequent commit modifies the line you specify as the `position`.
`path`	`string`	Required. The relative path to the file that necessitates a comment.
`position`	`integer`	Required without `comfort-fade` preview. The position in the diff where you want to add a review comment. Note this value is not the same as the line number in the file. For help finding the position value, read the note above.
`side`	`string`	Required with `comfort-fade` preview. In a split diff view, the side of the diff that the pull request's changes appear on. Can be `LEFT` or `RIGHT`. Use `LEFT` for deletions that appear in red. Use `RIGHT` for additions that appear in green or unchanged lines that appear in white and are shown for context. For a multi-line comment, side represents whether the last line of the comment range is a deletion or addition. For more information, see "Diff view options" in the GitHub Help documentation.
`line`	`integer`	Required with `comfort-fade` preview. The line of the blob in the pull request diff that the comment applies to. For a multi-line comment, the last line of the range that your comment applies to.
`start_line`	`integer`	Required when using multi-line comments. To create multi-line comments, you must use the `comfort-fade` preview header. The `start_line` is the first line in the pull request diff that your multi-line comment applies to. To learn more about multi-line comments, see "Commenting on a pull request" in the GitHub Help documentation.
`start_side`	`string`	Required when using multi-line comments. To create multi-line comments, you must use the `comfort-fade` preview header. The `start_side` is the starting side of the diff that the comment applies to. Can be `LEFT` or `RIGHT`. To learn more about multi-line comments, see "Commenting on a pull request" in the GitHub Help documentation. See `side` in this table for additional context.

Example for a multi-line comment

{
   "path": "test-plan.md",
   "start_line": 1,
   "start_side": "LEFT",
   "line": 3,
   "side": "RIGHT",
   "body": "Can you expand on this?"
 }

Example for a single-line comment

{
   "path": "test-plan.md",
   "line": 5,
   "side": "LEFT",
   "body": "Let's add this deleted line back."

Multi-line comment summary

Use the comfort-fade preview header and the line parameter to show multi-line comment-supported fields in the response.

If you use the comfort-fade preview header, your response will show:

For multi-line comments, values for start_line, original_start_line, start_side, line, original_line, and side.
For single-line comments, values for line, original_line, and side and a null value for start_line, original_start_line, and start_side.

If you don't use the comfort-fade preview header, multi-line and single-line comments will appear the same way in the response with a single position attribute. Your response will show:

For multi-line comments, the last line of the comment range for the position attribute.
For single-line comments, the diff-positioned way of referencing comments for the position attribute. For more information, see position in the input parameters table.
