|---|---|---|

0 0 * * 0 |

0 0 1 * * |
First of every month | Monthly billing or reports. |
15 * * * * |
At :15 past every hour | Avoid the top-of-hour rush. |

HTTP endpoints, Pub/Sub topics, and App Engine HTTP targets. Authentication uses OIDC tokens, OAuth tokens, or no auth (for public endpoints).
Cloud Scheduler retries with exponential backoff. Configure max retries, max retry duration, and backoff parameters per job. Failed jobs surface as logs and can trigger alerts.
Yes: gcloud scheduler jobs pause JOB_NAME. Resume with gcloud scheduler jobs resume. Paused jobs don't execute but remain in your job list.
