/comments

Adds a comment comment by the user to a specific file, or as a reply to an other comment.

Request

application/json

Query Parameters

string arrayin queryoptional
id,type,name

A comma-separated list of attributes to include in the response. This can be used to request fields that are not normally returned in a standard response.

Be aware that specifying this parameter will have the effect that none of the standard fields are returned in the response unless explicitly specified, instead only fields for the mini representation are returned, additional to the fields requested.

Request Body

objectin body

The item to attach the comment to.

stringin bodyrequired
11446498

The ID of the item

stringin bodyrequired
file

The type of the item that this comment will be placed on.

Value is one of "file", "comment"

stringin bodyrequired
Review completed!

The text of the comment.

To mention a user, use the tagged_message parameter instead.

stringin bodyoptional
@[1234:John] Review completed!

The text of the comment, including @[user_id:name] somewhere in the message to mention another user, which will send them an email notification, letting them know they have been mentioned.

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.

If you are not mentioning another user, use message instead.

Response

application/jsonComment

Returns the newly created comment object.

Not all available fields are returned by default. Use the fields query parameter to explicitly request any specific fields.

You can now try out some of our APIs live, right here in the documentation.
