Answer: Expect provider throttling and Postifys lane concurrency. Back off on failures, serialize heavy video jobs, and read Rate limits.
What this means in a real publishing workflow
Rate limits differ by platform, endpoint, account, and app approval level. The safest automation reacts to actual 429 responses and retry hints instead of assuming a universal daily quota.
Recommended implementation
- Separate publishing lanes by platform and destination account.
- Honor Retry-After when it is returned.
- Use exponential backoff with jitter for temporary failures.
- Cap retries and send the final error to Post History or an operator queue.
How to verify the fix
Do not retry validation errors such as an oversized YouTube title or missing Pinterest board. Correct those inputs first. Retry only transient capacity, provider, or network failures.
Operational check: Test with one item, confirm the final destination and Postifys history state, and only then enable the recurring workflow. Keep the returned Postifys ID beside the source row so every result remains traceable.
