Mechanic is a development and ecommerce automation platform for Shopify. :)
Use this task to delete all of your product or product variant metafields, optionally filtering by namespace or by namespace and key. This task will then delete all metafields found. This task comes with a test mode – use this first to make sure you're deleting the right things.
Runs Occurs when a user manually triggers the task and Occurs when a bulk operation is completed. Configuration includes delete product metafields, delete product variant metafields, metafield namespace, metafield key, and test mode.
Use this task to delete all of your product or product variant metafields, optionally filtering by namespace or by namespace and key. This task will then delete all metafields found. This task comes with a test mode – use this first to make sure you're deleting the right things.
With no configuration, this task will delete all product or product variant metafields. Configure it with a metafield namespace to only delete metafields with that namespace, or add both a namespace and key to get even more specific. Run this task with the test mode option enabled, the first time, to make sure you're deleting the right material.
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.
(By the way, have you seen our documentation? Have you joined the Slack community?)

As a rule, preview events should render realistic
action definitions. However, because Mechanic derives
a task's required permissions from these definitions,
and because a metafieldDelete mutation doesn't include
anything indicating what kind of resource the
metafield belongs to, we have to render an additional
spurious preview-only mutation to nudge Mechanic into
giving us write access to products.
