# Marketing analytics Track campaign performance and attributed revenue Marketing analytics imports ad performance data into Stripe and attributes customers and revenue to campaigns. Use it to: - See which campaigns bring in new customers and net revenue. - Measure return on ad spend (ROAS) with metrics that account for subscriptions, trial conversions, refunds, and disputes. - Send opt-in conversion signals back to ad platforms to help improve campaign optimization. ### Join the waitlist Enter your email to request early access. ```bash curl https://docs.stripe.com/preview/register \ -X POST \ -H "Content-Type: application/json" \ -H "Referer: https://docs.stripe.com/reports/marketing-analytics" \ -d '{"email": "EMAIL", "preview": "marketing_analytics_preview"}' ```
