# Scheduler

Scheduler — REST API reference.

The Scheduler module sends an Email, SMS or Push campaign on a cron schedule (5 fields, UTC), running as you or a service user of the project. Email, SMS and Push campaign tasks can be saved (`EmailCampaign`, `SmsCampaign`, `PushCampaign`); code-function and webhook tasks are refused. Use Enable / Disable to pause a task, and the module endpoints to turn the whole module off or on. In Cloud: [Tasks](/codemash/cloud/tasks.md).
