# Adds the ability to restrict card funding types in Checkout Sessions ## What’s new Adds the [funding_types_blocked](https://docs.stripe.com/api/checkout/sessions/create.md?api-version=2026-08-26.dahlia#create_checkout_session-payment_method_options-card-restrictions-funding_types_blocked) parameter to the [payment_method_options.card.restrictions](https://docs.stripe.com/api/checkout/sessions/create.md?api-version=2026-08-26.dahlia#create_checkout_session-payment_method_options-card-restrictions) hash on [Checkout Sessions](https://docs.stripe.com/api/checkout/sessions.md?api-version=2026-08-26.dahlia). This allows you to prevent cards with any of the specified funding types (`credit`, `debit`, and `prepaid`) from being used in the session. ## Impact You can now control which card funding types to accept at checkout by restricting certain funding types in the Checkout Session. For example, you can block prepaid cards to help reduce free-trial abuse or limit subscription payments to only credit cards. If the customer attempts to pay with a card of a restricted funding type, the Checkout Session shows an error. ## Changes #### REST API | Parameter | Change | Resources or endpoints | | --- | --- | --- | | `funding_types_blocked` | Added | [Checkout.Session#create.payment_method_options.card.restrictions](/api/checkout/sessions/create?api-version=2026-08-26.dahlia#create_checkout_session-payment_method_options-card-restrictions), [Checkout.Session.payment_method_options.card.restrictions](/api/checkout/sessions/object?api-version=2026-08-26.dahlia#checkout_session_object-payment_method_options-card-restrictions) | #### Ruby | Parameter | Change | Resources or methods | | --- | --- | --- | | `funding_types_blocked` | Added | [Checkout::Session::PaymentMethodOption::Card::Restriction](/api/checkout/sessions/object?api-version=2026-08-26.dahlia#checkout_session_object-payment_method_options-card-restrictions), [Checkout::SessionCreateParams::PaymentMethodOption::Card::Restriction](/api/checkout/sessions/create?api-version=2026-08-26.dahlia#create_checkout_session-payment_method_options-card-restrictions) | #### Python | Parameter | Change | Resources or methods | | --- | --- | --- | | `funding_types_blocked` | Added | [Checkout.Session.PaymentMethodOption.Card.Restriction](/api/checkout/sessions/object?api-version=2026-08-26.dahlia#checkout_session_object-payment_method_options-card-restrictions), [checkout.SessionCreateParamsPaymentMethodOptionCardRestriction](/api/checkout/sessions/create?api-version=2026-08-26.dahlia#create_checkout_session-payment_method_options-card-restrictions) | #### PHP | Parameter | Change | Resources or methods | | --- | --- | --- | | `funding_types_blocked` | Added | [Checkout.Session.payment_method_options.card.restrictions](/api/checkout/sessions/object?api-version=2026-08-26.dahlia#checkout_session_object-payment_method_options-card-restrictions), [Checkout\Session.create().$params.payment_method_option.card.restriction](/api/checkout/sessions/create?api-version=2026-08-26.dahlia#create_checkout_session-payment_method_options-card-restrictions) | #### Java | Parameter | Change | Resources or methods | | --- | --- | --- | | `fundingTypesBlocked` | Added | [checkout.Session.payment_method_options.card.restrictions](/api/checkout/sessions/object?api-version=2026-08-26.dahlia#checkout_session_object-payment_method_options-card-restrictions), [checkout.SessionCreateParams.payment_method_options.card.restrictions](/api/checkout/sessions/create?api-version=2026-08-26.dahlia#create_checkout_session-payment_method_options-card-restrictions) | #### Node.js | Parameter | Change | Resources or methods | | --- | --- | --- | | `funding_types_blocked` | Added | [Checkout.Session.payment_method_options.card.restrictions](/api/checkout/sessions/object?api-version=2026-08-26.dahlia#checkout_session_object-payment_method_options-card-restrictions), [Checkout.SessionCreateParams.payment_method_options.card.restrictions](/api/checkout/sessions/create?api-version=2026-08-26.dahlia#create_checkout_session-payment_method_options-card-restrictions) | #### Go | Parameter | Change | Resources or methods | | --- | --- | --- | | `FundingTypesBlocked` | Added | [CheckoutSessionPaymentMethodOptionsCardRestrictions](/api/checkout/sessions/object?api-version=2026-08-26.dahlia#checkout_session_object-payment_method_options-card-restrictions), [CheckoutSessionPaymentMethodOptionsCardRestrictionsParams](/api/checkout/sessions/create?api-version=2026-08-26.dahlia#create_checkout_session-payment_method_options-card-restrictions) | #### .NET | Parameter | Change | Resources or methods | | --- | --- | --- | | `FundingTypesBlocked` | Added | [Checkout.Session.PaymentMethodOptions.Card.Restrictions](/api/checkout/sessions/object?api-version=2026-08-26.dahlia#checkout_session_object-payment_method_options-card-restrictions), [CheckoutSessionPaymentMethodOptionsCardRestrictionsOptions](/api/checkout/sessions/create?api-version=2026-08-26.dahlia#create_checkout_session-payment_method_options-card-restrictions) | ## Upgrade #### REST API 1.
