To add an additional category and connect an existing service to it: 1. Call [Create Category](https://dev.wix.com/docs/rest/business-solutions/bookings/services/categories-v2/create-category.md), specifying the `name`. Save the returned category ID. 1. Call [Update Service](https://dev.wix.com/docs/rest/business-solutions/bookings/services/services-v2/update-service.md), specifying the new category ID as `service.category.id`. 1. Optional: If you want to change the display order for categories, call [Move Category](https://dev.wix.com/docs/rest/business-solutions/bookings/services/categories-v2/move-category.md). You can move the category to the beginning, end, or immediately after another category.
