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.

cURL

curl -i -X POST "https://api.box.com/2.0/comments" \
     -H "authorization: Bearer <ACCESS_TOKEN>" \
     -H "content-type: application/json" \
     -d '{
       "message": "Review completed!",
       "item": {
         "type": "file",
         "id": 426436
       }
     }'

.NET

var requestParams = new BoxCommentRequest()
{
    Item = new BoxRequestEntity()
    {
        Type = BoxType.File,
        Id = "12345"
    },
    Message = "Great work!"
};
BoxComment comment = await client.CommentsManager.AddCommentAsync(requestParams);

Java

BoxFile file = new BoxFile(api, "id");
file.addComment("This file is pretty cool.");

Python

comment = client.file(file_id='11111').add_comment('When should I have this done by?')

Node

client.comments.create('33333', 'Is this the latest version?')
    .then(comment => {
        /* comment -> {
            type: 'comment',
            id: '11111',
            is_reply_comment: false,
            message: 'Is this the latest version?',
            created_by: 
            { type: 'user',
                id: '22222',
                name: 'Example User',
                login: 'user@example.com' },
            created_at: '2012-12-12T11:25:01-08:00',
            item: { id: '33333', type: 'file' },
            modified_at: '2012-12-12T11:25:01-08:00' }
        */
    });

iOS

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)\"")
}

TypeScript (Beta)

await client.comments.createComment({
  message: message,
  item: {
    id: newComment.id!,
    type: 'comment' as CreateCommentRequestBodyItemTypeField,
  } satisfies CreateCommentRequestBodyItemField,
} satisfies CreateCommentRequestBody);

Python (Beta)

client.comments.create_comment(message, CreateCommentItem(id=new_comment.id, type=CreateCommentItemTypeField.COMMENT.value))

.NET (Beta)

await client.Comments.CreateCommentAsync(requestBody: new CreateCommentRequestBody(message: message, item: new CreateCommentRequestBodyItemField(id: NullableUtils.Unwrap(newComment.Id), type: CreateCommentRequestBodyItemTypeField.Comment)));

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.
