A tier represents a class of service or a logical grouping of subscriber accounts.
The Subscriber Interface consists of the following Tiers management requests:
- Add Tier: Allows users to add new tiers to their system. If a tier already exists with the given identifier (Name), this is considered an update, and the new tier replaces the existing one. All relationships between that tier and other objects in the system (for example, accounts) are maintained.
- Update Tier: Allows users to update tiers within their system. If no object exists with the given identifier (Name), this is a failure condition, and the object is not saved.
- Delete Tier: Allows users to delete a tier.
- Query Tier: Allows users to query a specific tier or list of tiers, returning their configured attributes.
