}Why letmepost vs Meta Graph direct?

- You handle the Page Access Token exchange
- You implement multi-photo (sequential upload + finalize)

- You parse Page-vs-User token errors
- You wrestle with the per-Page rate-limit headers
letmepost API
- Our reviewed Meta app covers hosted users
- Page tokens exchanged + cached server-side
- Up to 10 photos as one POST
- Video posts via single /videos endpoint, abstracted
- Errors normalized to letmepost's stable envelope
- Per-Page rate limit surfaced as structured 429s

Common questions
about facebook page posting
When does Facebook go live?
Publisher shipped, in Meta App Review (shared with IG + Threads). Typical 8–12 weeks.
Personal profile vs Page?
Pages only. Meta has restricted personal-profile API publishing for years.
How do I post to multiple Pages?
Each Page is a separate accountId in letmepost. One consent fans out to all the Pages the user picks.
Video uploads?
Via the /videos endpoint. We handle multipart upload + status poll. Max ~4GB, ~240 minutes (Facebook's limits).
Can I post to a Group?
Not in v1. Groups have a separate API with different scopes.
One API · 8 platforms
Facebook is just one of them.
