A nice way to do this is to use the databricks python sdk : 

(%pip install databricks-sdk)

from databricks.sdk import WorkspaceClient
if condition:
    DATABRICKS_HOST = "your-hostname"
    DATABRICKS_TOKEN = "your-personnal-access-token"
    w = WorkspaceClient(host=DATABRICKS_HOST, token=DATABRICKS_TOKEN)
    w.jobs.run_now(your-job-id)
