We use webhook in Jira DC a lot. Now we are considering to adopt Jira cloud and want to have similar webhook functionality in Jira cloud. We have A4J which is little more secure than traditional webhook feature in Jira cloud.
Even though in A4J, one can secure API by adding Authorization header, but that does not fulfil organisation security needs..
We are looking for MATLS feature which is to ensure connection are trusted from Jira Cloud to on-premise CI systems and vice-versa.
We use webhook to trigger CI pipeline if any configured events occurs.
