# Posts a comment on a task.

> Comments default to `ConversationTypeId: 2` (Private). Any other kind is
outward-facing, so posting one puts the task in a waiting-on-the-contact state and fires
the same automation the app does.
            
Side Conversation (3) and Approval (4) need the `ConversationId` of a conversation
that already exists on this task - list them with the conversations endpoint.
            
Attach files by uploading them first and sending back the name and url you were given.
Any access token on a url is stripped before storage and a fresh one is issued whenever
the comment is read, so never store the url you get back.
