# Create Loyalty Campaign

> Creates a batch of <!-- [loyalty cards](OpenAPI.json/components/schemas/8_obj_loyalty_card_object) -->[loyalty cards](ref:get-member) aggregated in a single loyalty campaign. It also allows you to define a custom codes pattern.  

<!-- theme: info -->
> 📘 Global uniqueness
> All codes are unique across the whole project. Voucherify won't allow to generate the same codes in any of your campaigns.

<!-- theme: warning -->
> 🚧 Asynchronous action!
>
> This is an asynchronous action, you can't read or modify a newly created campaign until the code generation is completed. See `creation_status` field in the <!-- [loyalty campaign object](OpenAPI.json/components/schemas/8_obj_loyalty_campaign_object) -->[loyalty campaign object](ref:get-loyalty-program) description.
