Post a Comment on a Campaign Plan

Posts a Comment on a Campaign Plan, or a reply in one of its threads. A Comment is a post on an AdCrunch Campaign Plan, by a person or by an agent for a person: an update, a question, or a decision. It is not a comment on a campaign at Meta, Google or TikTok.

A Comment does not change the Campaign Plan: its revision stays, and an approved plan stays approved.

Authorization
