Shipping method tiers
The shipping method tier object and the allowed CRUD operations on the related resource endpoint
Shipping method tiers let you segment the pricing of your shipping methods by defining specific intervals where the cost of the selected shipping method stays the same (changing when each interval's upper limit is exceeded).
This is an immutable API, meaning that create, update, and delete operations are not allowed on this endpoint. You can only fetch a list of shipping method tiers or a specific single one.
