Hi @GANAPATI_HEGDE ,

According to docs:

• For service principal: Set service_principal_name to the application ID. Requires the servicePrincipal/user role. If not specified, the alert will run as the request user.

So instead of using service principal name try to pass application ID.

Where do i pass the service principal name?

Can you share the docs as well so that i can read about it?

Hi, 

It's described at their REST API docs:

Create an alert | Alerts V2 API | REST API reference | Databricks on AWS

It doesnt really explain where to set the run as username for alerts, when i check in the jobs UI, i dont see option to set run_as as well

Create Alert in regular way. After your alert is created:

1. Go to Alerts

2. Select your alert

3. Click pencil next to run as to edit:

4. Provide application id of your service principal and clik save:

unfortunately, only these options are available in my UI, is it the new UI?

Yes, it seems that you're  using legacy alerts:

To switch to alerts v2 follow this guide:
