This would exponentially increase the usefulness of this already great tool.

Use-Case: A customer has created a custom event for a specific type of issuetype, called Incident Created. This event is not available for Webhooks. I can, in the meantime, assign a Post-Function to this Webhook but this makes administration more painful.
In addition to supporting custom events, it would be highly beneficial if Jira Webhooks included enhanced logging and tracking capabilities. This feature would allow users to track each Webhook event with a unique identifier, facilitating better error recovery and auditing. Such capabilities would greatly improve the administration and reliability of integrations that rely on Webhooks, providing a comprehensive history of events that can be referenced if service interruptions occur.
