Browser companion terms
Use only Pages you are authorized to manage and posts you own or have permission to publish. Review the Page, original photo or video and caption before approving publication. You are responsible for content and compliance with Meta’s terms.
Meta may reject, delay or limit publication. An accepted API request is not proof that a post is publicly visible. Check the actual Facebook result. Do not repeat an uncertain upload without checking your Page.
Meta App Review approval and uninterrupted publication are not guaranteed. See the MMO Creator Studio terms.
