Pull request review comments

About the Pull request review comments API

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."

Custom media types for pull request review comments

These are the supported media types for pull request review comments.

application/vnd.github.VERSION.raw+json
application/vnd.github.VERSION.text+json
application/vnd.github.VERSION.html+json
application/vnd.github.VERSION.full+json

For more information, see "Custom media types."

An additional reactions object in the issue comment payload is currently available for developers to preview. During the preview period, the APIs may change without advance notice. Please see the blog post for full details.

To access the API you must provide a custom media type in the Accept header:

application/vnd.github.squirrel-girl-preview

The reactions key will have the following payload where url can be used to construct the API location for listing and creating reactions.

Multi-line comments in a pull request diff is currently available for developers to preview. During the preview period, these response fields may change without advance notice. See the blog post for more information.

To create multi-line comments or see multi-line comments with the new supported fields during the preview period, you must provide a custom media type in the Accept header:

application/vnd.github.comfort-fade-preview+json

To show multi-line comment-supported fields in the response, use the comfort-fade preview header and the line parameter.

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.

Create a review comment for a pull request

Works with GitHub Apps

Creates a review comment in the pull request diff. To add a regular comment to a pull request timeline, see "Create an issue comment." 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 the comfort-fade preview notice.

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.

This endpoint triggers notifications. Creating content too quickly using this endpoint may result in secondary rate limiting. See "Secondary rate limits" and "Dealing with secondary rate limits" for details.

`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. Can be one of: `LEFT`, `RIGHT`, `side`

Preview notice

Multi-line comments in a pull request diff is currently available for developers to preview. During the preview period, these response fields may change without advance notice. See the blog post for more information.

To create multi-line comments or see multi-line comments with the new supported fields during the preview period, you must provide a custom media type in the Accept header:

application/vnd.github.comfort-fade-preview+json

To show multi-line comment-supported fields in the response, use the comfort-fade preview header and the line parameter.

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.

Create a reply for a review comment

Creates a reply to a review comment for a pull request. For the comment_id, provide the ID of the review comment you are replying to. This must be the ID of a top-level review comment, not a reply to that comment. Replies to replies are not supported.

This endpoint triggers notifications. Creating content too quickly using this endpoint may result in secondary rate limiting. See "Secondary rate limits" and "Dealing with secondary rate limits" for details.
