Known Pitfalls
| Pitfall | Details |
|---|---|
| Scheduling too close to now | FACEBOOK_CREATE_POST with scheduled_publish_time less than ~10 minutes in the future returns HTTP 400 -- enforce a larger buffer for bulk runs |
| Unix UTC timestamps required | scheduled_publish_time must be Unix UTC -- timezone conversion mistakes cause off-by-hours sched |
