Would love to have a feature to notify our helpdesk users on their mobile phone through the Jira mobile app when new issues gets created.
Go to your Project Settings -> Project Automation -> New Rule
( For next-gen project automation is under project settings -> Apps -> Project Automation)
Create an automation rule when an issue is created and applies to the rules that you want and just put a comment in the ticket mentioning you. This will trigger a push notification to your phone and an in-app notification.
To mention you in the ticket you need to follow this format:
Make sure to replace <<account_id>> with the user's Account ID that you want to notify.
You can find this by going to Jira Administration > Users, then clicking on the User you want to notify, The final part of the URL after /users/ will be the user's Account ID or using the REST API endpoint below:
Also, you can use the one below directly on the browser:
