COMMON QUESTIONS
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.
