# Removes the source type parameter when creating new Stripe balance payment methods ## What’s new Removes the ability to specify the [source_type](https://docs.stripe.com/api/payment_methods/object.md?api-version=2025-12-15.preview#payment_method_object-stripe_balance-source_type) when creating [Stripe balance](https://docs.stripe.com/api/payment_methods/object.md?api-version=2026-01-28.preview#payment_method_object-stripe_balance) payment methods. `source_type` is now set to null for new Stripe balance payment methods. ## Impact Previously, the `source_type` parameter was required when creating Stripe balance payment methods. You can no longer specify the `source_type` when creating Stripe balance payment methods—Stripe now returns an error if you include `source_type`. If your integration creates Stripe balance payment methods, update your code to remove the `source_type` parameter during creation, as well as handle cases where this property is null. Existing Stripe balance payment methods are not affected by this change. ## Changes #### REST API | Fields | Change | From → to | | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | --------------------------------------------------------------------------------- | | `Charge.payment_method_details.stripe_balance.source_type`, `ConfirmationToken.payment_method_preview.stripe_balance.source_type`, `PaymentAttemptRecord.payment_method_details.stripe_balance.source_type`, `PaymentMethod.stripe_balance.source_type`, `PaymentRecord.payment_method_details.stripe_balance.source_type` | Changed | `enum('bank_account'|'card'|'fpx') → nullable(enum('bank_account'|'card'|'fpx'))` | #### Ruby | Fields | Change | From → to | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | --------------------------------------------------------------------------------- | | `Charge::PaymentMethodDetail::StripeBalance.source_type`, `ConfirmationToken::PaymentMethodPreview::StripeBalance.source_type`, `PaymentAttemptRecord::PaymentMethodDetail::StripeBalance.source_type`, `PaymentMethod::StripeBalance.source_type`, `PaymentRecord::PaymentMethodDetail::StripeBalance.source_type` | Changed | `enum('bank_account'|'card'|'fpx') → nullable(enum('bank_account'|'card'|'fpx'))` | #### Python | Fields | Change | From → to | | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | --------------------------------------------------------------------------------- | | `Charge.PaymentMethodDetail.StripeBalance.source_type`, `ConfirmationToken.PaymentMethodPreview.StripeBalance.source_type`, `PaymentAttemptRecord.PaymentMethodDetail.StripeBalance.source_type`, `PaymentMethod.StripeBalance.source_type`, `PaymentRecord.PaymentMethodDetail.StripeBalance.source_type` | Changed | `enum('bank_account'|'card'|'fpx') → nullable(enum('bank_account'|'card'|'fpx'))` | #### PHP | Fields | Change | From → to | | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | --------------------------------------------------------------------------------- | | `Charge.payment_method_details.stripe_balance.source_type`, `ConfirmationToken.payment_method_preview.stripe_balance.source_type`, `PaymentAttemptRecord.payment_method_details.stripe_balance.source_type`, `PaymentMethod.stripe_balance.source_type`, `PaymentRecord.payment_method_details.stripe_balance.source_type` | Changed | `enum('bank_account'|'card'|'fpx') → nullable(enum('bank_account'|'card'|'fpx'))` | #### Java This change does not affect the Java SDK. #### Node.js | Fields | Change | From → to | | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------- | ------------------------------------------------------------------------------ | | `Charge.payment_method_details.stripe_balance.source_type`, `ConfirmationToken.payment_method_preview.stripe_balance.source_type`, `PaymentAttemptRecord.payment_method_details.stripe_balance.source_type`, `PaymentMethod.stripe_balance.source_type`, `PaymentRecord.payment_method_details.stripe_balance.source_type` | Changed | `enum('bank_account'|'card'|'fpx') → enum('bank_account'|'card'|'fpx') | null` | #### Go This change does not affect the Go SDK. #### .NET This change does not affect the .NET SDK. ## Upgrade #### REST API 1.
