# Adds parameter to link Verification Sessions to Customers ## What’s new Adds `related_customer` to the Identity [Verification Session](https://docs.stripe.com/api/identity/verification_sessions.md?api-version=2024-09-30.acacia) resource. When you [create](https://docs.stripe.com/api/identity/verification_sessions/create.md?api-version=2024-09-30.acacia) or [update](https://docs.stripe.com/api/identity/verification_sessions/update.md?api-version=2024-09-30.acacia) a Verification Session, you can optionally include a token to reference an existing [Customer](https://docs.stripe.com/api/customers.md?api-version=2024-09-30.acacia). ## Impact Linking [Customers](https://docs.stripe.com/api/customers.md?api-version=2024-09-30.acacia) to their identity verifications provides a more visibility into the risk profile of your customer base, helping you make more informed decisions about onboarding, monitoring, and risk mitigation. ##
