InventoryTransfer

Requires read_inventory_transfers access scope.

Supported actions: create, update, delete

Subscribe to field-level changes on the InventoryTransfer GraphQL Admin API object.

Each topic corresponds to a commerce resource that can exist independently within its domain. Child entities that depend on a parent within the same domain don't have their own topic. Instead, changes to child entities trigger a delivery on the parent topic. Calculated fields, derived fields, auto-updated timestamps, and cross-domain fields aren't available as triggers.
