Answer: Retry only the failed platform jobs. Check Postifys history first, use exponential backoff, and never blind-replay a whole multi-platform fan-out after a partial success.
Why blind retries are dangerous
A fan-out that succeeded on Instagram but failed on YouTube will create a duplicate Instagram post if you replay the entire workflow.
Safe retry checklist
- Read Post History (or your stored job ids) and mark each destination success/fail.
- Branch in n8n: only failed destinations continue.
- Backoff on rate limits and “processing” states.
- Change media/title only when the failure reason requires it (e.g. empty YouTube title).
- Stop after a fixed attempt budget; alert a human.
