Hey @Alan_G - On a slightly related, it would be great to see the OrderLineItemDeleteCustomAttributeMutation be exposed to the Public Admin API - Last time I checked I saw it’s only available via the Internal API (Someone please correct me if I am wrong).
I think this could potentially also solve the other people’s use cases as an interim solution, since it’s already available within the Admin and therefore shouldn’t have any downstream effects that aren’t already triggerable within the Admin.
For some context, we have a setup where we use signed line item attributes to manipulate prices via functions, these attributes are then unpacked into an order level Metafield via a custom app. We tap into these attributes within email templates, functions, etc. but post-order, our point of reference is now that order level Metafield - Which we can make edits to.
It would be great if we can clear our these attributes via the Admin API, once we drop the data into an Order Metafield, for a cleaner Admin experience (These attributes are not very pretty).
