Mechanic is a development platform for Shopify. :)
This task monitors inventory updates, and pulls the product from the selected sales channels whenever a product's total inventory meets your "out of stock" threshold. Optionally, it'll send you an email when it does so. This task can also be run manually, to scan all products at once.
Runs when a user triggers the task and when an inventory level is updated. Configuration includes sales channel names, email notification recipient, and out of stock inventory quantity.

This task monitors inventory updates, and pulls the product from the selected sales channels whenever a product's total inventory meets your "out of stock" threshold.
To scan your entire catalog for out of stock products, use the "Run task" button. Otherwise, this task will run whenever an inventory level is updated.
If you'd like to wait until the product has been out of stock for several days, use this task instead: Unpublish products that have been out of stock for x days.
Mechanic is designed to benefit everybody: merchants, customers, developers, agencies, Gurus, everybody.
That’s why we make it easy to configure automation without code, why we make it easy to tweak the underlying code once tasks are installed, and why we publish it all here for everyone to learn from.
