new

tags_removed

Shopify regularly releases new webhook topics, and this routine doesn't normally warrant a Mechanic changelog entry. But, these specific topics signal something meaningfully new.

Shopify's names for these topics are
customer.tags_added
and
customer.tags_removed
. Note that those terms are separated by dots, not slashes. Historically, Shopify has only ever named topics using slashes. (Over here in Mechanic, we're rolling with slashes anyway, for internal consistency:
shopify/customer/tags_added
, and
shopify/customer/tags_removed
.)
These webhook payloads don't contain the entire Customer object's REST representation, which is a break from tradition with
customers/create
et al. Instead, they contain information styled à la GraphQL, instead of REST.

Mechanic tasks have typically needed to work hard to determine the delta of a resource's attributes over time. This is the first time that Shopify has released a webhook

the substance of a change*, which relieves task-writers of some specific headaches.

orders/edited

exists, but even then, its payload is the static content of an OrderEdit, not the delta of an Order.
