  * `automatic_tax` - Settings for automatic tax lookup for this invoice preview.
  * `currency` - The currency to preview this invoice in. Defaults to that of `customer` if not specified. Format: ISO 4217 currency code.
  * `customer` - The identifier of the customer whose upcoming invoice you're retrieving. If `automatic_tax` is enabled then one of `customer`, `customer_details`, `subscription`, or `schedule` must be set. Max length: 5000.
  * `customer_account` - The identifier of the account representing the customer whose upcoming invoice you're retrieving. If `automatic_tax` is enabled then one of `customer`, `customer_account`, `customer_details`, `subscription`, or `schedule` must be set. Max length: 5000.
  * `customer_details` - Details about the customer you want to invoice or overrides for an existing customer. If `automatic_tax` is enabled then one of `customer`, `customer_details`, `subscription`, or `schedule` must be set.
  * `discounts` - The coupons to redeem into discounts for the invoice preview. If not specified, inherits the discount from the subscription or customer. This works for both coupons directly applied to an invoice and coupons applied to a subscription. Pass an empty string to avoid inheriting any discounts.
  * `expand` - Specifies which fields in the response should be expanded.
  * `invoice_items` - List of invoice items to add or update in the upcoming invoice preview (up to 250).
  * `issuer` - The connected account that issues the invoice. The invoice is presented with the branding and support information of the specified account.
  * `on_behalf_of` - The account (if any) for which the funds of the invoice payment are intended. If set, the invoice will be presented with the branding and support information of the specified account. See the [Invoices with Connect](https://docs.stripe.com/billing/invoices/connect) documentation for details.
  * `preview_mode` - Customizes the types of values to include when calculating the invoice. Defaults to `next` if unspecified. Possible values: `next`, `recurring`.
  * `schedule` - The identifier of the schedule whose upcoming invoice you'd like to retrieve. Cannot be used with subscription or subscription fields. Max length: 5000.
  * `schedule_details` - The schedule creation or modification params to apply as a preview. Cannot be used with `subscription` or `subscription_` prefixed fields.
  * `subscription` - The identifier of the subscription for which you'd like to retrieve the upcoming invoice. If not provided, but a `subscription_details.items` is provided, you will preview creating a subscription with those items. If neither `subscription` nor `subscription_details.items` is provided, you will retrieve the next upcoming invoice from among the customer's subscriptions. Max length: 5000.
  * `subscription_details` - The subscription creation or modification params to apply as a preview. Cannot be used with `schedule` or `schedule_details` fields.

  * `description` - Subscription description, meant to be displayable to the customer. Use this field to optionally store an explanation of the subscription for rendering in Stripe surfaces and certain local payment methods UIs.
  * `discounts` - The coupons to redeem into discounts for the schedule phase. If not specified, inherits the discount from the subscription's customer. Pass an empty string to avoid inheriting any discounts.

Individual keys in the subscription's `metadata` can be unset by posting an empty value to them in the phase's `metadata`. To unset all keys in the subscription's `metadata`, update the subscription directly or unset every key individually from the phase's `metadata`.
  * `on_behalf_of` - The account on behalf of which to charge, for each of the associated subscription's invoices.
  * `proration_behavior` - Controls whether the subscription schedule should create [prorations](https://docs.stripe.com/billing/subscriptions/prorations) when transitioning to this phase if there is a difference in billing configuration. It's different from the request-level [proration_behavior](https://docs.stripe.com/api/subscription_schedules/update#update_subscription_schedule-proration_behavior) parameter which controls what happens if the update request affects the billing configuration (item price, quantity, etc.) of the current phase. Possible values: `always_invoice`, `create_prorations`, `none`.
  * `start_date` - The date at which this phase of the subscription schedule starts or `now`. Must be set on the first phase.
  * `transfer_data` - The data with which to automatically create a Transfer for each of the associated subscription's invoices.
  * `trial` - If set to true the entire phase is counted as a trial and the customer will not be charged for any fees.
