Today, the new automation-based feedback collector requires that the contact email is passed through the webhook. Without this, feedback will not be created.
For teams aggregating feedback for multiple sources, or teams not heavily relying on the contact record in Aha!, this can be an unneeded extra step.
Proxy votes in Aha! today can be added without a contact listed, though the organization is required. It should be optional to pass the contact through the automation as well.
Set the automation rules to review and add contact details if they are provided, but do not make this required.
