# Method name: bulkCreateTiers(tiers: Array<Tier>)

# Method package: wixLoyaltyV2

# Method menu location: wixLoyaltyV2 --> tiers --> bulkCreateTiers

# Method Link: https://dev.wix.com/docs/velo/apis/wix-loyalty-v2/tiers/bulk-create-tiers.md

# Method Description:

Creates up to 20 tiers.

>or a [Business plan](https://support.wix.com/en/article/choosing-a-premium-plan?tabs=Business) (Wix Editor) to add tiers.
