Respect rate limits and use backoff
Coordinate App9 Post and provider limits without creating retry storms or duplicate posts.
Throttle by credential and provider, honor retry guidance, and use exponential backoff with jitter for transient failures. Keep publication idempotency and result reconciliation in place because a rate-limited or timed-out provider request can still have an ambiguous remote outcome.
What this means in practice
Throttle by credential and provider, honor retry guidance, and use exponential backoff with jitter for transient failures. Keep publication idempotency and result reconciliation in place because a rate-limited or timed-out provider request can still have an ambiguous remote outcome.
Use the documented brand and account boundaries consistently across the scheduler, REST API, SDK, MCP tools, SSE consumers, and webhooks. That makes the same social operation explainable to an operator and reproducible by an integration.
Implementation checklist
Set bounded client concurrency for bulk account, analytics, and feed work.
Honor Retry-After or structured reset information when present.
Apply jitter so many workers do not retry simultaneously.
Separate transient network or 5xx failures from permission and validation failures.
Alert on sustained provider-specific throttling and growing synchronization lag.
Operational details
App9 Post serializes provider and credential-sensitive work, but clients still need responsible API behavior.
Different endpoint families and providers can have different cost and limit models.
A lower request rate can be more reliable than maximizing instantaneous throughput.
Common mistakes to avoid
- Do not retry immediately in a tight loop.
- Do not increase concurrency when a provider reports throttling.
- Do not abandon idempotency because the original request returned no response.
