# Adds support for card installments on Confirmation Token ## What’s new [Confirmation Token](https://docs.stripe.com/api/confirmation_tokens.md?api-version=2025-04-30.basil) objects created by the Payment Element contain [payment_method_options.card.installments](https://docs.stripe.com/api/confirmation_tokens/object.md?api-version=2025-04-30.basil#confirmation_token_object-payment_method_options-card-installments) if the cardholder selected an [installment plan](https://docs.stripe.com/payments/mx-installments.md). In addition, when you [create a test Confirmation Token](https://docs.stripe.com/api/confirmation_tokens/test_create.md?api-version=2025-04-30.basil) you can also supply an installment plan in [payment_method_options.card.installments.plan](https://docs.stripe.com/api/confirmation_tokens/test_create.md?api-version=2025-04-30.basil#test_create-payment_method_options-card-installments-plan). ## Impact This change coincides with the release of card installments support on the Payment Element and adds visibility into cardholder choices. ## Changes #### REST API | Parameters | Change | Resources or endpoints | | ------------------------ | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `payment_method_options` | Added | [ConfirmationToken.testHelpers#create](/api/confirmation_tokens/test_create?api-version=2025-04-30.basil) | | `installments` | Added | [ConfirmationToken.payment_method_options.card](/api/confirmation_tokens/object?api-version=2025-04-30.basil#confirmation_token_object-payment_method_options-card) | #### Ruby | Parameters | Change | Resources or methods | | ------------------------ | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | `payment_method_options` | Added | [ConfirmationToken::CreateParams](/api/confirmation_tokens/test_create?api-version=2025-04-30.basil) | | `installments` | Added | [ConfirmationToken::PaymentMethodOption::Card](/api/confirmation_tokens/object?api-version=2025-04-30.basil#confirmation_token_object-payment_method_options-card) | #### Python | Parameters | Change | Resources or methods | | ------------------------ | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `payment_method_options` | Added | [ConfirmationToken.CreateParams](/api/confirmation_tokens/test_create?api-version=2025-04-30.basil) | | `installments` | Added | [ConfirmationToken.PaymentMethodOption.Card](/api/confirmation_tokens/object?api-version=2025-04-30.basil#confirmation_token_object-payment_method_options-card) | #### PHP This change does not affect the PHP SDK. #### Java | Parameters | Change | Resources or methods | | ---------------------- | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `paymentMethodOptions` | Added | [ConfirmationTokenCreateParams](/api/confirmation_tokens/test_create?api-version=2025-04-30.basil) | | `installments` | Added | [ConfirmationToken.payment_method_options.card](/api/confirmation_tokens/object?api-version=2025-04-30.basil#confirmation_token_object-payment_method_options-card) | #### Node.js | Parameters | Change | Resources or methods | | ------------------------ | ------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `payment_method_options` | Added | [ConfirmationTokenCreateParams.testHelpers](/api/confirmation_tokens/test_create?api-version=2025-04-30.basil) | | `installments` | Added | [ConfirmationToken.payment_method_options.card](/api/confirmation_tokens/object?api-version=2025-04-30.basil#confirmation_token_object-payment_method_options-card) | #### Go | Parameters | Change | Resources or methods | | ---------------------- | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `PaymentMethodOptions` | Added | [ConfirmationTokenParams](/api/confirmation_tokens/test_create?api-version=2025-04-30.basil) | | `Installments` | Added | [ConfirmationTokenPaymentMethodOptionsCard](/api/confirmation_tokens/object?api-version=2025-04-30.basil#confirmation_token_object-payment_method_options-card) | #### .NET | Parameters | Change | Resources or methods | | ---------------------- | ------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `PaymentMethodOptions` | Added | [TestHelpersConfirmationTokenCreateOptions](/api/confirmation_tokens/test_create?api-version=2025-04-30.basil) | | `Installments` | Added | [ConfirmationTokenPaymentMethodOptionsCard](/api/confirmation_tokens/object?api-version=2025-04-30.basil#confirmation_token_object-payment_method_options-card) | ## Upgrade #### REST API 1.
