What Posthook is
Posthook is a webhook scheduler for reminders, follow-ups, notifications, and expirations, available through its web service and API. You schedule a target path, delivery time, and custom payload, then use recurring hourly, daily, weekly, or monthly schedules with daylight-saving handling and chained steps. Webhook activity can be inspected, with bulk retry or replay by endpoint and time range. Retries support fixed or exponential backoff with jitter and do not count toward quota. Deliveries use HTTPS and HMAC-SHA256 signatures, replay protection, and signing-key rotation. Posthook says hooks enter a durable queue before the API responds, with at-least-once delivery and configurable retries. Official TypeScript, Python, and Go SDKs are listed, along with compatibility with several web frameworks and services. Plans range from Free to Launch at $39 a month, Growth at $99 a month, and Scale at $249 a month.
