Alteration hook info in webhook payload

Hi,

We have a requirement to trigger an external action when a specific alteration is applied on a policy.

We're currently using webhooks to drive these action, but in this case I want to know if a specific type of alteration was executed when listening to POLICY_ALTERATION_PACKAGE_APPLIED subscriptions.

I see there is a alteration_package_id returned as part of the event. Is there a specific endpoint I can use to get more info on the specific alteration that was executed?
