# Adds reference and company details parameters for Billie ## What’s new Adds two optional parameters to the [Billie](https://docs.stripe.com/payments/billie.md) payment method: - [reference](https://docs.stripe.com/api/payment_intents/create.md?api-version=2026-09-30.endive#create_payment_intent-payment_method_options-billie): A string that identifies the transaction. You can use this parameter with [Payment Intents](https://docs.stripe.com/api/payment_intents/create.md?api-version=2026-09-30.endive#create_payment_intent-payment_method_options-billie) and [Invoices](https://docs.stripe.com/api/invoices/create.md?api-version=2026-09-30.endive#create_invoice-payment_settings-payment_method_options-billie). - [company_details](https://docs.stripe.com/api/payment_intents/create.md?api-version=2026-09-30.endive#create_payment_intent-payment_method_options-billie): An object that contains `registered_name`, `registration_type`, `registration_number`, `vat`, and `registered_address`. You can use this parameter with [Payment Intents](https://docs.stripe.com/api/payment_intents/create.md?api-version=2026-09-30.endive#create_payment_intent-payment_method_options-billie), [Invoices](https://docs.stripe.com/api/invoices/create.md?api-version=2026-09-30.endive#create_invoice-payment_settings-payment_method_options-billie), and [Subscriptions](https://docs.stripe.com/api/subscriptions/create.md?api-version=2026-09-30.endive#create_subscription-payment_settings-payment_method_options-billie). The corresponding properties appear on the response objects for each resource. ## Impact You can now optionally include additional `company_details` and a `reference` identifier when you use the Billie payment method for Payment Intents, Invoices, or Subscriptions (`reference` is not supported for Subscriptions). These parameters don’t affect existing integrations as they’re additive and optional. Providing this information to Billie can improve authorization rates. ## Changes #### REST API | Parameters | Change | Resources or endpoints | | --- | --- | --- | | `company_details`, `reference` |
