I'm looking for a program that can automatically log in to a Jira instance and create a placeholder task at regular intervals to prevent the instance from being deactivated after 30 days of no use. I will provide a list of usernames and passwords for the program to handle logins autonomously. The programming language is flexible, so I'm open to your suggestions on the best option for this implementation. Key functionality includes ensuring smooth operation and secure management of credentials. If you're experienced with Jira Atlassian environments and can deliver a reliable solution, I’d love to hear from you.
