API Polling

* In Plain English

Webhook retries, queue drain, and external API polling schedules.

* Scheduling Guide

API polling schedules keep your system in sync with external services by running queries at regular intervals — every minute, every five minutes, or hourly depending on how fresh the data needs to be. The key tradeoff is poll frequency versus rate-limit headroom: polling too often burns API quota and risks 429 errors, while polling too infrequently means stale data. A common pattern is a short interval (e.g. */2 * * * *) for high-priority webhooks that need near-real-time delivery, and a longer window (e.g. 0 * * * *) for bulk feed ingestion where a one-hour lag is acceptable. Backoff and retry logic should sit inside the job itself, not in the schedule, so a transient failure does not cascade into a missed run.
