# Adds network fee details to estimated fees on Outbound Payment Quotes ## What’s new Adds a `network_fee` value to the [estimated_fees[].type](https://docs.stripe.com/api/v2/money-management/outbound-payment-quotes/object.md?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees-type) enum and a [network_fee_details](https://docs.stripe.com/api/v2/money-management/outbound-payment-quotes/object.md?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees-network_fee_details) property on estimated fee items for [Outbound Payment Quotes](https://docs.stripe.com/api/v2/money-management/outbound-payment-quotes.md?api-version=2026-09-30.preview). The `network_fee_details` property is an optional object that contains the payment network (for example, `ach`, `swift`, `sepa`, or `rtp`) and any network-specific options. ## Impact If your integration reads `estimated_fees[].type` on [Outbound Payment Quotes](https://docs.stripe.com/api/v2/money-management/outbound-payment-quotes/object.md?api-version=2026-09-30.preview), you might receive the `network_fee` value. Make sure your code handles this additional enum value. When `type` is `network_fee`, use the `network_fee_details` property to identify the specific network and any network-specific options. For guidance on selecting a payment network and reviewing estimated fees, see [Send money](https://docs.stripe.com/global-payouts/send-money.md#select-a-payment-network). ## Changes #### REST API | Parameter | Change | Resources or endpoints | | --- | --- | --- | | `network_fee_details` | Added | [V2.MoneyManagement.OutboundPaymentQuote.estimated_fees[]](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees) | | Value | Change | Enum | | --- | --- | --- | | `network_fee` | Added | [V2.MoneyManagement.OutboundPaymentQuote.estimated_fees[].type](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees-type) | #### Ruby | Parameter | Change | Resources or methods | | --- | --- | --- | | `network_fee_details` | Added | [V2::MoneyManagement::OutboundPaymentQuote::EstimatedFee](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees) | #### Python | Parameter | Change | Resources or methods | | --- | --- | --- | | `network_fee_details` | Added | [V2.MoneyManagement.OutboundPaymentQuote.EstimatedFee](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees) | | Value | Change | Enum | | --- | --- | --- | | `network_fee` | Added | [V2.MoneyManagement.OutboundPaymentQuote.EstimatedFee.type](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees-type) | #### PHP | Parameter | Change | Resources or methods | | --- | --- | --- | | `network_fee_details` | Added | [V2.MoneyManagement.OutboundPaymentQuote.estimated_fees[]](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees) | | Value | Change | Enum | | --- | --- | --- | | `network_fee` | Added | [V2.MoneyManagement.OutboundPaymentQuote.estimated_fees[].type](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees-type) | #### Java | Parameter | Change | Resources or methods | | --- | --- | --- | | `networkFeeDetails` | Added | [v2.moneymanagement.OutboundPaymentQuote.EstimatedFee](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees) | #### Node.js | Parameter | Change | Resources or methods | | --- | --- | --- | | `network_fee_details` | Added | [V2.MoneyManagement.OutboundPaymentQuote.estimated_fees[]](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees) | | Value | Change | Enum | | --- | --- | --- | | `network_fee` | Added | [V2.MoneyManagement.OutboundPaymentQuote.estimated_fees[].type](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees-type) | #### Go | Parameter | Change | Resources or methods | | --- | --- | --- | | `NetworkFeeDetails` | Added | [V2MoneyManagementOutboundPaymentQuoteEstimatedFee](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees) | | Value | Change | Enum | | --- | --- | --- | | `network_fee` | Added | [V2MoneyManagementOutboundPaymentQuoteEstimatedFee.Type](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees-type) | #### .NET | Parameter | Change | Resources or methods | | --- | --- | --- | | `NetworkFeeDetails` | Added | [V2.MoneyManagement.OutboundPaymentQuote.EstimatedFee](/api/v2/money-management/outbound-payment-quotes/object?api-version=2026-09-30.preview#v2_outbound_payment_quote_object-estimated_fees) | ## Upgrade #### REST API 1.
