# Renames the parameter for custom settlement timing on the Balance Settings API ## What’s new This change renames the top-level `delay_days` parameter of the [Balance Settings API](https://docs.stripe.com/api/balance-settings/update.md?api-version=2025-07-30.preview) to [delay_days_override](https://docs.stripe.com/api/balance-settings/update.md?api-version=2025-07-30.preview#update_balance_settings-settlement_timing-delay_days_override) to clearly distinguish between Stripe’s default settlement timing and whether your platform requests to override that computed delay. Platforms can request a specific `delay_days_override` by creating or updating Balance Settings. Stripe uses the request to determine the final number of days to hold charge funds before they become available. If your platform doesn’t explicitly request a `delay_days_override`, we apply default settlement timing. ## Why is this a breaking change? We renamed the `delay_days` parameter to `delay_days_override`. ## Impact If you participate in the [Accounts v2 API](https://docs.stripe.com/connect/accounts-v2.md) public preview and want to use API version `2025-07-30.preview` or later, you need to update your integration to use the new parameter name. If your integration relies on the ability to specify your own settlement timing with `delay_days`, update your Balance Settings integration to use the `delay_days_override` parameter. ## Changes #### REST API | Parameters | Change | Resources or endpoints | | --------------------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------- | | `delay_days_override` | Added | [BalanceSettings#update.settlement_timing](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | | `delay_days` | Removed | [BalanceSettings#update.settlement_timing](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | #### Ruby | Parameters | Change | Resources or methods | | --------------------- | ------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- | | `delay_days_override` | Added | [BalanceSettings::UpdateParams::SettlementTiming](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | | `delay_days` | Removed | [BalanceSettings::UpdateParams::SettlementTiming](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | #### Python | Parameters | Change | Resources or methods | | --------------------- | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- | | `delay_days_override` | Added | [BalanceSettings.ModifyParamsSettlementTiming](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | | `delay_days` | Removed | [BalanceSettings.ModifyParamsSettlementTiming](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | #### PHP This change does not affect the PHP SDK. #### Java | Parameters | Change | Resources or methods | | ------------------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ | | `delayDaysOverride` | Added | [BalanceSettingsUpdateParams.settlement_timing](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | | `delayDays` | Removed | [BalanceSettingsUpdateParams.settlement_timing](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | #### Node.js | Parameters | Change | Resources or methods | | --------------------- | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- | | `delay_days_override` | Added | [BalanceSettingUpdateParams.settlement_timing](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | | `delay_days` | Removed | [BalanceSettingUpdateParams.settlement_timing](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | #### Go | Parameters | Change | Resources or methods | | ------------------- | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------- | | `DelayDaysOverride` | Added | [BalanceSettingsSettlementTimingParams](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | | `DelayDays` | Removed | [BalanceSettingsSettlementTimingParams](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | #### .NET | Parameters | Change | Resources or methods | | ------------------- | ------- | ----------------------------------------------------------------------------------------------------------------------------------------------- | | `DelayDaysOverride` | Added | [BalanceSettingsSettlementTimingOptions](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | | `DelayDays` | Removed | [BalanceSettingsSettlementTimingOptions](/api/balance-settings/update?api-version=2025-07-30.preview#update_balance_settings-settlement_timing) | ## Upgrade #### REST API 1.
