Documentation

Use this task with the companion unpublishing task (see this task's documentation) to make a certain collection of products available on a schedule, and unavailable on another schedule.

For best results, pair this task with Unpublish a certain collection, daily, from our task library.

To configure this task, enter the "Collection ID" for the collection you wish to publish. Refer to this article for assistance on finding Shopify resource IDs.

Out of the box, this task will publish everything in this collection at 9am on weekdays, and 10am on weekends. To adjust this, click the "Show Advanced" link, and tweak the "Subscriptions" setting to taste. Each line represents midnight in your shop's local timezone, plus whatever number of hours you prefer. For example, mechanic/scheduler/tuesday+13.hours would mean Tuesday at 1pm.

Note: This task only publishes products to the 'Online Store'.
