How to set up multiple alerts in your tenant

With the Overrides feature, you can set a different alerts source for specific SharePoint sites, allowing site-specific alerts to be displayed.

1. First, you will need to complete all three steps from our configuration guide. Repeat the process for each per-site alert source you'll need.
2. Navigate to the Alerts extension configuration panel available in your SharePoint site's Site Contents.
3. In this panel, you can insert JSON to instruct the Alerts extension which SharePoint sites will be connected to each alert data source.
4. In the panel, insert JSON to specify which SharePoint sites should use each alert data source. Replace the bold items in the example below with your site URLs:
   

   {
   "default":{
   "sourceSiteUrl":"https://yourdomain.sharepoint.com/sites/yoursite"
   },
     "overrides": [
        {
          "sites": ["\/sites\/othersite"],
        "sourceSiteUrl":"https://yourdomain.sharepoint.com/sites/othersite"
        }
      ]
   }

5. Click on Save. The Alerts app will validate your configuration.
