Webhooks should include the userId of the person who initiated the event
We use webhooks to connect other api's and it would be a huge benefit if the webhook would include the user id of the person who initiated the event. For instance ContactCreate, have a "createdbyuserid" so we know which user created it. Here are a few more examples where including the userid makes sense: OutboundMessage -> who sent it? OpportunityCreate -> who created it. TaskCreate -> who created it.
