Success Messages confirm that an action completed successfully. Provides closure and positive reinforcement. Can be toast (temporary), banner (persistent), or inline (near action). Use green color and checkmark icon. Keep brief and specific: "Invoice sent" not "Action completed successfully."
Use success messages for completed actions: form submissions, payments, saves, sends, deletions, imports. Be specific about what succeeded: "3 users invited" not "Success!". Provide next action when relevant: "Invoice sent" + "View invoice" link. Use toast for quick confirmations, banner for important milestones, inline for form success.
