Developer Preview
APIs in Developer Preview are subject to change and are not intended for use in production.
Send us your suggestions for improving this API. Your feedback is valuable to us.
  The Labels API provides functionality for managing labels for your site. Labels allow site admins to segment or categorize the contacts in their Contact List. Using Labels enchances the CRM by allowing site admins to customize data organization according to their needs. For example, you can use labels to target specific audiences for email campaigns or bulk actions. Learn more about [labels](https://support.wix.com/en/article/creating-contact-labels). With the Labels API, you can: - [Create](/labels/find-or-create-label) a new label. - [Update](/labels/rename-label) a label by renaming its display name. - [Delete](/labels/delete-label) a label. - [Query](/labels/query-labels) labels. ## Before you begin It is important to note the following points before you begin to code: - When you delete a label from your site, you also remove that label from all contacts it applies to. - Label keys can't be changed once created. To use the Labels API, import `{ labels }` from the `wix-crm.v2` module. ```javascript import { labels } from 'wix-crm.v2'; ``` ## Permissions information Functions in the Labels API are restricted and only run if you elevate permissions using the `wix-auth` [`elevate()`](https://www.wix.com/velo/reference/wix-auth/elevate) function.

Warning: Elevating a function allows it to be called by any site visitor. Exercise caution to prevent security vulnerabilities.
