    /**
     * Updates an existing subscription to match the specified parameters. When

     * month to make up for any price changes. To preview how the proration is
     * calculated, use the <a href="/docs/api/invoices/upcoming">upcoming invoice</a>
     * endpoint.
     *
     * By default, we prorate subscription changes. For example, if a customer signs up
     * on May 1 for a <currency>100</currency> price, they’ll be billed
     * <currency>100</currency> immediately. If on May 15 they switch to a
     * <currency>200</currency> price, then on June 1 they’ll be billed
     * <currency>250</currency> (<currency>200</currency> for a renewal of her
     * subscription, plus a <currency>50</currency> prorating adjustment for half of
     * the previous month’s <currency>100</currency> difference). Similarly, a
     * downgrade generates a credit that is applied to the next invoice. We also
     * prorate when you make quantity changes.
     *
     * Switching prices does not normally change the billing date or generate an
     * immediate charge unless:
     *
     * <ul> <li>The billing interval is changed (for example, from monthly to
     * yearly).</li> <li>The subscription moves from free to paid, or paid to
     * free.</li> <li>A trial starts or ends.</li> </ul>
     *
     * In these cases, we apply a credit for the unused time on the previous price,
     * immediately charge the customer using the new price, and reset the billing date.
     *
     * If you want to charge for an upgrade immediately, pass
     * <code>proration_behavior</code> as <code>always_invoice</code> to create
     * prorations, automatically invoice the customer for those proration adjustments,
     * and attempt to collect payment. If you pass <code>create_prorations</code>, the
     * prorations are created but not automatically invoiced. If you want to bill the
     * customer for the prorations before the subscription’s renewal date, you need to
     * manually <a href="/docs/api/invoices/create">invoice the customer</a>.
     *
     * If you don’t want to prorate, set the <code>proration_behavior</code> option to
     * <code>none</code>. With this option, the customer is billed
     * <currency>100</currency> on May 1 and <currency>200</currency> on June 1.
     * Similarly, if you set <code>proration_behavior</code> to <code>none</code> when
     * switching between different billing intervals (for example, from monthly to
     * yearly), we don’t generate any credits for the old subscription’s unused time.
     * We still reset the billing date and bill immediately for the new subscription.
     *
     * Updating the quantity on a subscription many times in an hour may result in <a
     * href="/docs/rate-limits">rate limiting</a>. If you need to bill for a frequently
     * changing quantity, consider integrating <a
     * href="/docs/billing/subscriptions/usage-based">usage-based billing</a> instead.
