Updates the global settings of a loyalty tier program.
Use this endpoint to update settings that apply to all of a site's loyalty tiers. To update tier-specific settings for an individual tier, use Update Tier.
By default, the status of a tiers program is set to DISABLED and must be manually updated to ACTIVE using
this endpoint or through a site owner's dashboard.
Note: The status, revision, and rollingWindow parameters must be passed to update the tiers program settings.
The baseTierDefinition fields are not required, however, if you don't pass them they will reset to
their default values of empty fields.
You can only call this method when authenticated as a Wix app or Wix user identity.
