Mechanic is a development and ecommerce automation platform for Shopify. :)
Shopify's product collection filters allow you to filter by the tags the product contains – but not the tags a product does not contain. Use this task to sync an "inverse" tag to all products who do not have a particular tag, allowing you to create collections in Shopify that use the inverse tag.
Runs Occurs whenever a product is created, Occurs whenever a product is updated, or whenever a product is ordered, or whenever a variant is added, removed, or updated, Occurs when a user manually triggers the task, and Occurs when a bulk operation is completed. Configuration includes product tag to watch and product tag to use when missing.
Shopify's product collection filters allow you to filter by the tags the product contains – but not the tags a product does not contain. Use this task to sync an "inverse" tag to all products who do not have a particular tag, allowing you to create collections in Shopify that use the inverse tag.
To explain by example, if you've already tagged your wholesale products with "wholesale", configure the "Product tag to watch" option with "wholesale", and the "Product tag to use when missing" option with "retail". This task will automatically tag all non-wholesale products with "retail", and automatically remove that tag from any products who later receive the tag "wholesale". Please note: if you remove the "retail" tag, this task will simply re-add it. To remove the "retail" tag, you would need to add the "wholesale" tag to that product.
Run this task manually to scan all of the products in your store. Otherwise, this task will monitor and sync tags for all new and updated products, as they come through.
Mechanic is designed to benefit everybody: merchants, customers, developers, agencies, Shopifolks, 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.
