Whenever inventory for a product is updated, this task scans all variants and all fulfillment locations, adds up all inventory related to that product, and makes sure the product is hidden if the total inventory meets your "out of stock" threshold. Optionally, it'll send you an email when it does so.
Runs when a user triggers the task and when an inventory level is updated. Configuration includes email notification recipient, only monitor products with these tags, and out of stock inventory quantity.
Whenever inventory for a product is updated, this task scans all variants and all fulfillment locations, adds up all inventory related to that product, and makes sure the product is hidden if the 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.
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.
