## Introduction

Triggered when a Category is updated.
Includes changes to its `label` or `assignedTo` list. Assignment changes made with
Bulk Assign Categories to Program can trigger this event for each updated Category.
The related Program's `categoryIds` list is synchronized asynchronously and may
still contain the previous assignments when this event is received.

Webhook: Category Updated
Description: Triggered when a Category is updated. Includes changes to its `label` or `assignedTo` list. Assignment changes made with Bulk Assign Categories to Program can trigger this event for each updated Category. The related Program's `categoryIds` list is synchronized asynchronously and may still contain the previous assignments when this event is received.
Event body:
 - name: id | type: string | description: Unique event ID. Allows clients to ignore duplicate events.
 - name: entityFqdn | type: string | description: Fully qualified domain name of the entity associated with the event.
 - name: slug | type: string | description: Event name.
 - name: entityId | type: string | description: ID of the entity associated with the event.
 - name: eventTime | type: string (date-time) | description: Event timestamp.
 - name: triggeredByAnonymizeRequest | type: boolean | description: Whether the event was triggered as a result of a privacy regulation application such as GDPR.
 - name: originatedFrom | type: string | description: If present, indicates the action that triggered the event.
 - name: updatedEvent | type: object | description: Updated event details.
    - name: currentEntity | type: Category | description: The entity after the update.
        - name: id | type: string | description: Category GUID.
        - name: revision | type: string | description: Revision number, which increments by 1 each time the Category is updated. To prevent conflicting changes, the current `revision` must be passed when updating the Category.
        - name: createdDate | type: string | description: Date and time the Category was created.
        - name: updatedDate | type: string | description: Date and time the Category was last updated.
        - name: label | type: string | description: Category's display label. The primary-language label must be unique within the site. Localized reads return the Wix Multilingual translation when one exists, and otherwise fall back to the primary label.
        - name: assignedTo | type: array<string> | description: IDs of Programs assigned to this Category. For routine assignment changes, use [Bulk Assign Categories to Program](https://dev.wix.com/docs/api-reference/business-management/online-programs/categories/bulk-assign-categories-to-program.md), whose 10-Category-per-Program check is best-effort. Direct writes to `assignedTo` through Create Category, Bulk Create Categories, or Update Category bypass that check; callers using them must keep each Program at or below 10 Categories. Relationship updates are eventually consistent across the Program Categories and Programs APIs.
        - name: extendedFields | type: ExtendedFields | description: Custom field data for the Category. [Extended fields](https://dev.wix.com/docs/rest/articles/getting-started/extended-fields.md) must be configured in the app dashboard for `wix.achievements.categories.v3.category` before they can be accessed with API calls.
           - name: namespaces | type: object | description: Extended field data. Each key corresponds to the namespace of the app that created the extended fields. The value of each key is structured according to the schema defined when the extended fields were configured.  You can only access fields for which you have the appropriate permissions.  Learn more about [extended fields](https://dev.wix.com/docs/rest/articles/getting-started/extended-fields.md).

You can use this number to make sure you're handling updates in the right order. Just save the latest sequence number on your end and compare it to the one in each new message. If the new message has an older (lower) number, you can safely ignore it.

### Examples


```javascript
import { categories } from '@wix/online-programs';

categories.onCategoryUpdated((event) => {
    // handle your event here
});
```


```javascript
import { createClient, AppStrategy } from '@wix/sdk';
import { categories } from '@wix/online-programs';

const wixClient = createClient({
  auth: AppStrategy({
    appId: 'MY-APP-ID',
    publicKey: 'YOUR_APP_PUBLIC_KEY',
  }),
  modules: {
      categories,
