Yes, you can filter results in the knowledge portal by the predefined knowledge base article labels. When you filter by label, the knowledge portal only surfaces articles that are tagged with that label. This feature allows you to use the same article in different knowledge portals and avoid multiple maintenance efforts for the same article.

Use the following API endpoints to update the draft version of a deployment configuration and publish it.

  "supportCenter": {
    ...
    "labelFilter": {
      "labels": [
        {"id": "f2892c40-3f6d-49d2-8401-e29e92415971"}
      ]
    },
    ...
  ...
}

Publish the configuration draft

After you have updated the configuration draft, you can publish it using one of the following methods:

• In Genesys Cloud, click Menu > Digital and Telephony > Message > Messenger Configurations, then publish a new version. 
• Use the API endpoint: POST /api/v2/webdeployments/configurations/{configurationId}/versions/draft/publish to publish the configuration draft and create a new version.

Then, you can update the deployment to use the newly published configuration.
