Can postfast post to my personal Facebook profile?

No. Facebook’s API allows publishing to Pages, not to personal profiles. That is Facebook’s rule and it applies to every scheduling tool.

Can I connect more than one Page?

Yes. Each Page is its own connected account, subject to your plan’s social-account allowance, and each gets its own delivery status on every post.

Does Facebook support threads in postfast?

No. A Page post cannot reply to itself in a way that chains, so postfast blocks a thread aimed at Facebook rather than publishing only its first part.

Platforms — Facebook

Schedule Facebook Page posts

Connect a Facebook Page and schedule posts to it alongside every other network, with per-Page delivery status.

Facebook

Pages, not personal profiles

Facebook’s publishing API serves Pages. postfast connects through Facebook Login for Business and reaches your Pages from there, which is the supported route. A personal profile cannot be published to by any tool, ours included.

Facebook is also the one network in postfast whose own character limit sits above ours: it takes 63,206 characters against the 5,000 a postfast post may carry. The guard counts against whichever is tighter, so it warns at the limit that will actually stop the post rather than the bigger number that reads better.

What Facebook accepts in one post

Read from the same capability table the composer warns from and the publisher builds payloads from. postfast's own bound of 5,000 characters and 4 media items applies on top, whichever is tighter.

Characters: 63,206 per post.
Media items: 10 per post on Facebook's side; postfast accepts 4.
Media required: No. A text-only post publishes fine.
Threads: Not available. Facebook has no self-reply, so a thread cannot be chained here — Publish Guard blocks a thread aimed at it rather than publishing the first part alone.
Cost per post: Nothing. The platform charges no API fee for publishing.
Scheduling: postfast holds the post and hands it over at the moment it is due, so a post can be scheduled a minute out or a year out.

How connecting works

Facebook Login for Business. You approve postfast and pick the Pages it may publish to. Access is per Page, so a Page you did not select is not reachable.
Tokens are sealed at rest. Encrypted under the application secret and returned by no endpoint.
Handles or ids, both linkable. A Page lives at its vanity handle when it has one and at its numeric id when it does not. postfast links either, so a Page with no vanity name still gets a working profile link.
Meta’s deletion callback reaches it. Facebook is covered by the same Meta data-deletion endpoint as Threads and Instagram.

What you get

Several Pages, one calendar

Connect every Page you run, aim a post at the ones that need it, and each carries its own delivery record.

No thread promises

A Page post takes no self-reply, so postfast refuses a thread aimed at Facebook rather than publishing part of it.

Free per post

Nothing about publishing to a Page is metered.

Verbatim errors

When Meta rejects a post, you see what Meta said, not a paraphrase of it.
