User creation and collaboration often includes a number of details that should be recorded and auditable by Box Admins. When a user is created, there is often a sponsor, a ticket or request ID, and potentially a rationale, project name, or dozens of other information that needs to be remembered by the organization. Likewise, when collaborations are created, there is often additional context that should be auditable after the fact - what is the reason for the collaboration, what is the project or ticket ID that led to the request, who is the sponsor - this is especially important for external collaboration.

Box should allow users to add these details to the event so that they are surfaced in a user activity report under "details" for that event. Ideally, this would be possible in the web application but at minimum this should be possible when APIs are used to create a user or create a collaboration.
