Create Comment

Create Comment

To create a comment, call the POST /comments API with the message of the comment, as well as the ID of the file to leave the comment on.

    },
    Message = "Great work!"
};
BoxComment comment = await client.CommentsManager.AddCommentAsync(requestParams);

            id: '11111',

                name: 'Example User',
                login: 'user@example.com' },
            created_at: '2012-12-12T11:25:01-08:00',

client.comments.create(
    itemId: "11111",
    itemType: "file",
    message: "Thanks!"
) { (result: Result<Comment, BoxSDKError>) in
    guard case let .success(comment) = result else {
        print("Error creating comment")
        return
    }

    print("Added comment to \(comment.item.name): \"\(comment.message)\"")
}

A comment's message can also mentions users using the @ sign. To do so, add the string @[userid:name] anywhere within the message. The user_id is the target user's ID, where the name can be any custom phrase. In the Box UI this name will link to the user's profile.

Then, pass this string as the tagged_message instead of the message.
