The work between requests.With a timer you can inspect.

A scheduled job is useful when work should happen without a visitor clicking a button: a daily digest, a periodic cache refresh or a check on records that need attention. Fortly has two ways to run that work. An HTTP schedule requests a path in your application with GET. A Worker Cron Trigger calls the Worker’s scheduled(controller, env, ctx) handler. Both are visible in Deployments under Schedules.

For an HTTP application that already has a job endpoint, add an HTTP schedule with a name, cron expression and path. The request goes to the project’s own address and behaves like an ordinary application request. The endpoint should perform the intended work securely; a scheduled path does not automatically make a public route private. Store credentials in Variables when the job requires them, and validate your application’s access rules.

For a hand-written Worker, declare triggers.crons in wrangler config and deploy it with the scheduled handler. The timer belongs to the release configuration, so code and schedule can be reviewed together. This route calls scheduled(), not fetch(). Visitors cannot invoke the platform’s internal trigger path as an ordinary application endpoint.

Schedules use a five-field cron expression interpreted in UTC: minute, hour, day of month, month and day of week. A daily 03:00 job uses 0 3 * * *. Lists, ranges and steps support recurring patterns such as a weekday refresh. The docs show exact syntax, including the forms Fortly refuses rather than accepting a schedule that will never run.

The console keeps each timer’s next run, last run, duration and outcome together. Worker triggers are marked as config-owned, so they are distinguishable from HTTP schedules added in the UI. A successful handler is described as completed, rather than pretending its internal completion status is an application page response. Failed runs lead into runtime output where the application’s own error can be inspected.

Pause a timer while investigating or doing maintenance. Resuming does not replay runs missed while paused, and platform downtime does not create a catch-up queue. A run is limited to five minutes. Choose another workload model if the task requires a permanent process, a long-running batch or durable queue semantics. A cron timer decides when to ask for work; it does not turn the work into a transaction.

A Worker release that retains the same cron expression keeps its schedule history and paused state. Removing the expression from triggers.crons and deploying removes that trigger. The console allows pause and resume, but it does not offer a misleading delete action that a later deployment would silently undo. The API returns a conflict with instructions when someone tries to delete a config-owned trigger directly.

HTTP schedules are managed separately. Add or remove them through the console or API; to change an existing HTTP expression or path, remove it and create the replacement. Review the old timer before adding a new one so a maintenance change does not accidentally duplicate an important job. Keep descriptive names close to their purpose, such as Nightly invoice summary rather than a bare cron string.

Write jobs so a retry or repeated run does not corrupt data, and record useful completion or failure information. If a scheduled job sends email, its binding still needs a verified sender, confirmed destination and remaining allowance. If it changes PostgreSQL, its data access rules still apply. The timer connects to your app’s services; it does not bypass their permissions, quotas or storage models.
