Can I post to my personal Facebook profile?

No. Postbean publishes to Facebook Pages only.

This is Facebook’s rule, not a Postbean limitation: Meta’s Graph API does not offer publishing to personal profiles for third-party apps. No scheduling tool can do it, whatever it claims.

What to do instead

• Create a Page for whatever you are publishing and connect that. Pages also give you the reach and insights data that personal profiles do not expose.
• Post to your profile by hand for the things that genuinely belong there, and let Postbean handle the Page.

If your goal was reaching the same audience across Meta, connecting Instagram and Threads alongside the Page covers most of it — both are supported and both publish from the same composer.
