  , postSubscriptionItemsRequestBodyMetadata :: (GHC.Maybe.Maybe PostSubscriptionItemsRequestBodyMetadata')
  -- | payment_behavior: Use \`allow_incomplete\` to transition the subscription to \`status=past_due\` if a payment is required but cannot be paid. This allows you to manage scenarios where additional user actions are needed to pay a subscription\'s invoice. For example, SCA regulation may require 3DS authentication to complete payment. See the [SCA Migration Guide](https:\/\/stripe.com\/docs\/billing\/migration\/strong-customer-authentication) for Billing to learn more. This is the default behavior.
  -- 
  -- Use \`pending_if_incomplete\` to update the subscription using [pending updates](https:\/\/stripe.com\/docs\/billing\/subscriptions\/pending-updates). When you use \`pending_if_incomplete\` you can only pass the parameters [supported by pending updates](https:\/\/stripe.com\/docs\/billing\/pending-updates-reference\#supported-attributes).
  -- 
  -- Use \`error_if_incomplete\` if you want Stripe to return an HTTP 402 status code if a subscription\'s first invoice cannot be paid. For example, if a payment method requires 3DS authentication due to SCA regulation and further user action is needed, this parameter does not create a subscription and returns an error instead. This was the default behavior for API versions prior to 2019-03-14. See the [changelog](https:\/\/stripe.com\/docs\/upgrades\#2019-03-14) to learn more.

Valid values are \`create_prorations\`, \`none\`, or \`always_invoice\`.

-- | Defines the enum schema postSubscriptionItemsRequestBodyPayment_behavior\'
-- 
-- Use \`allow_incomplete\` to transition the subscription to \`status=past_due\` if a payment is required but cannot be paid. This allows you to manage scenarios where additional user actions are needed to pay a subscription\'s invoice. For example, SCA regulation may require 3DS authentication to complete payment. See the [SCA Migration Guide](https:\/\/stripe.com\/docs\/billing\/migration\/strong-customer-authentication) for Billing to learn more. This is the default behavior.
-- 
-- Use \`pending_if_incomplete\` to update the subscription using [pending updates](https:\/\/stripe.com\/docs\/billing\/subscriptions\/pending-updates). When you use \`pending_if_incomplete\` you can only pass the parameters [supported by pending updates](https:\/\/stripe.com\/docs\/billing\/pending-updates-reference\#supported-attributes).
-- 
-- Use \`error_if_incomplete\` if you want Stripe to return an HTTP 402 status code if a subscription\'s first invoice cannot be paid. For example, if a payment method requires 3DS authentication due to SCA regulation and further user action is needed, this parameter does not create a subscription and returns an error instead. This was the default behavior for API versions prior to 2019-03-14. See the [changelog](https:\/\/stripe.com\/docs\/upgrades\#2019-03-14) to learn more.
