Posting slots
Weekly posting times per account, and the next free slot for a post.
A posting slot is a weekly time a post goes out on one or more accounts: "every Monday at 09:30 in Europe/Berlin, for @shop on Instagram and Facebook". "Next free slot" picks the earliest slot where none of the post's accounts already has a post.
Posting slots are on every plan.
How a slot is picked
- A slot applies to a post when it posts for at least one of the post's accounts.
- A slot is taken when a scheduled post (or one waiting for approval, or publishing) targets one of the post's accounts within 5 minutes of it. Drafts do not take slots.
- The search covers the next 60 days.
- The slot returned is held for 10 minutes, so two requests at the same moment get different slots. Create the post at that time to keep it.
- Times are wall-clock times in the slot's zone and stay put when the clocks change. A time the clocks skip (02:30 on the spring-forward night) moves to just after the gap; a time that happens twice (01:30 on the fall-back night) uses the first one.
Up to 100 slots per user.
