The combined totalFeeBps (platform + partner) cannot exceed 500 bps (5%). Since the platform fee may change, the effective maximum for partnerFeeBps is 500 - platformFeeBps. Partner fees have a minimum of 10 bps when enabled - set to 0 to disable entirely.
If two requests update the policy concurrently, one will succeed and the other will receive a 409 Conflict. Simply retry on 409.
