# Adds PayPay onboarding parameters to the Accounts API ## What’s new Adds support for additional [PayPay onboarding parameters](https://docs.stripe.com/api/accounts/object.md?api-version=2026-01-28.preview#account_object-settings-paypay_payments) to the [Accounts API](https://docs.stripe.com/api/accounts.md?api-version=2026-01-28.preview). You can now provide complete PayPay configuration data when creating or updating connected accounts, including website accessibility settings and supplementary documentation files. The new parameters include: - [type](https://docs.stripe.com/api/accounts/object.md?api-version=2026-01-28.preview#account_object-settings-paypay_payments-site-type): Specifies whether your website is accessible, restricted, or in development - [username](https://docs.stripe.com/api/accounts/object.md?api-version=2026-01-28.preview#account_object-settings-paypay_payments-site-in_development-username) and [site_password](https://docs.stripe.com/api/accounts/object.md?api-version=2026-01-28.preview#account_object-settings-paypay_payments-site-in_development-password_provided): Required credentials for development websites - [additional_files](https://docs.stripe.com/api/accounts/object.md?api-version=2026-01-28.preview#account_object-settings-paypay_payments-additional_files): Array of file IDs for supplementary documentation Additionally, you can now update the [specified_commercial_transactions_act_url](https://docs.stripe.com/api/accounts/object.md?api-version=2026-01-28.preview#account_object-business_profile-specified_commercial_transactions_act_url) property through the API, which was previously only configurable through the Dashboard. ## Impact Your Connect platform can now provide complete PayPay onboarding data for your connected accounts without requiring manual Dashboard configuration. This enables a fully programmatic onboarding flow for [PayPay payments](https://docs.stripe.com/payments/paypay.md) in Japan. When uploading files for PayPay onboarding, use the `account_requirement` purpose with the [Files API](https://docs.stripe.com/api/files.md?api-version=2026-01-28.preview). The password parameter is write-only and returns a `password_provided` boolean property when reading account data for security purposes. ## Changes #### REST API | Parameters | Change | Resources or
