Jira Clouds doesn't support free alternatives to implement Java code. That is the only actual way of listening to Tempo Timesheets events.
It would be ideal to have Webhooks similar to what Jira have, so the Cloud instances can manage this events.
Tempo Products | Tempo Timesheets |
Tempo Platform | Cloud |
As Jira has made official that on premise installation is on end of life the Tempo webhook system is a must have feature
We also want this feature because we want to listen when customers / accounts ar created or changed.
