# Adds support for SEPA Direct Debit and Bacs Direct Debit mandate reference prefixes in Checkout Sessions ## What’s new We added the following API parameter to payment method options for SEPA Direct Debit and Bacs Direct Debit in [Checkout Sessions](https://docs.stripe.com/api/checkout/sessions.md?api-version=2024-11-20.acacia): - `bacs_debit.mandate_options.reference_prefix` - `sepa_debit.mandate_options.reference_prefix` ## Impact This change lets you specify mandate options when using Checkout with SEPA Direct Debit or Bacs Direct Debit. You can specify a prefix in the `mandate_options.reference_prefix` parameter to customize either the [SEPA Direct Debit Mandate reference](https://docs.stripe.com/api/mandates/object.md?api-version=2024-11-20.acacia#mandate_object-payment_method_details-sepa_debit-reference) or [Bacs Direct Debit Mandate reference](https://docs.stripe.com/api/mandates/object.md?api-version=2024-11-20.acacia#mandate_object-payment_method_details-bacs_debit-reference) in Payment and Setup modes. ## Changes #### REST API
