Webhook Retry Schedule Generator

Model exponential backoff before production. A retry policy should protect customer workflows without overwhelming a recovering endpoint.

Use this before production

  • Retry 5xx, network timeouts, and temporary rate limits.
  • Do not blindly retry permanent 4xx validation failures.
  • Use idempotency keys so retries cannot duplicate side effects.
  • Log every attempt before deciding a job is truly failed.
