Schedule a webhook to fire on a recurring cadence

The problem

You have a webhook URL and a cadence in mind, but nothing to pull the trigger on time. Wiring up a cron server or a serverless function just to send one HTTP request is more moving parts than the job deserves.

How to set it up

1. 1

   Point a schedule at the webhook URL

   Create a schedule with the webhook as its endpoint, set the method to POST, and add the JSON body the receiving service expects. Pick the cron expression and timezone for when it should fire.

   const report = await cronhost.createSchedule({ name: "Weekly report", cronExpression: "0 9 * * 1", // Mondays at 9am timezone: "America/New_York", endpoint: "https://hooks.slack.com/services/...", httpMethod: "POST", body: JSON.stringify({ text: "Weekly report is ready." }), });

   const report = await cronhost.createSchedule({ name: "Weekly report", cronExpression: "0 9 * * 1", // Mondays at 9am timezone: "America/New_York", endpoint: "https://hooks.slack.com/services/...", httpMethod: "POST", body: JSON.stringify({ text: "Weekly report is ready." }), });
2. 2

   Add headers if the receiver needs them

   If the webhook expects a content type or a signing/auth header, set them per schedule. Cronhost sends them with every request exactly as configured.

3. 3

   Let retries handle the flaky moments

   Set a retry count so a transient 5xx or a timeout on the receiving end does not drop the delivery. Cronhost retries with exponential backoff, and only the first attempt counts toward your monthly quota.
