Visit Add notifier page, configure all the necessary information to create a Jira notification service:
Click Test button to test the notifier, you should see an issue shortly on your Jira site. Otherwise, there is something wrong with your configuration.
Then save the notifier, waiting for your Shodan Monitor networks to trigger alerts and create issues. Note that if you leave Apply to existing alerts unchecked, you must configure it separately in your specified network.
