namespace EDD\Vendor\Stripe;

/**
 * Invoices are statements of amounts owed by a customer, and are either
 * generated one-off, or generated periodically from a subscription.
 *
 * They contain <a href="https://stripe.com/docs/api#invoiceitems">invoice items</a>, and proration adjustments
 * that may be caused by subscription upgrades/downgrades (if necessary).
 *
 * If your invoice is configured to be billed through automatic charges,
 * EDD\Vendor\Stripe automatically finalizes your invoice and attempts payment. Note
 * that finalizing the invoice,
 * <a href="https://stripe.com/docs/invoicing/integration/automatic-advancement-collection">when automatic</a>, does
 * not happen immediately as the invoice is created. EDD\Vendor\Stripe waits
 * until one hour after the last webhook was successfully sent (or the last
 * webhook timed out after failing). If you (and the platforms you may have
 * connected to) have no webhooks configured, EDD\Vendor\Stripe waits one hour after
 * creation to finalize the invoice.
 *
 * If your invoice is configured to be billed by sending an email, then based on your
 * <a href="https://dashboard.stripe.com/account/billing/automatic">email settings</a>,
 * EDD\Vendor\Stripe will email the invoice to your customer and await payment. These
 * emails can contain a link to a hosted page to pay the invoice.
 *
 * EDD\Vendor\Stripe applies any customer credit on the account before determining the
 * amount due for the invoice (i.e., the amount that will be actually
 * charged). If the amount due for the invoice is less than Stripe's <a href="/docs/currencies#minimum-and-maximum-charge-amounts">minimum allowed charge
 * per currency</a>, the
 * invoice is automatically marked paid, and we add the amount due to the
 * customer's credit balance which is applied to the next invoice.
 *
 * More details on the customer's credit balance are
 * <a href="https://stripe.com/docs/billing/customer/balance">here</a>.
 *
 * Related guide: <a href="https://stripe.com/docs/billing/invoices/sending">Send invoices to customers</a>
 *
 * @property null|string $id Unique identifier for the object. This property is always present unless the invoice is an upcoming invoice. See <a href="https://stripe.com/docs/api/invoices/upcoming">Retrieve an upcoming invoice</a> for more details.
 * @property string $object String representing the object's type. Objects of the same type share the same value.
 * @property null|string $account_country The country of the business associated with this invoice, most often the business creating the invoice.
 * @property null|string $account_name The public name of the business associated with this invoice, most often the business creating the invoice.
 * @property null|(string|\EDD\Vendor\Stripe\TaxId)[] $account_tax_ids The account tax IDs associated with the invoice. Only editable when the invoice is a draft.
 * @property int $amount_due Final amount due at this time for this invoice. If the invoice's total is smaller than the minimum charge amount, for example, or if there is account credit that can be applied to the invoice, the <code>amount_due</code> may be 0. If there is a positive <code>starting_balance</code> for the invoice (the customer owes money), the <code>amount_due</code> will also take that into account. The charge that gets generated for the invoice will be for the amount specified in <code>amount_due</code>.
 * @property int $amount_paid The amount, in cents (or local equivalent), that was paid.
 * @property int $amount_remaining The difference between amount_due and amount_paid, in cents (or local equivalent).
 * @property int $amount_shipping This is the sum of all the shipping amounts.
 * @property null|string|\EDD\Vendor\Stripe\Application $application ID of the Connect Application that created the invoice.
 * @property null|int $application_fee_amount The fee in cents (or local equivalent) that will be applied to the invoice and transferred to the application owner's EDD\Vendor\Stripe account when the invoice is paid.
 * @property int $attempt_count Number of payment attempts made for this invoice, from the perspective of the payment retry schedule. Any payment attempt counts as the first attempt, and subsequently only automatic retries increment the attempt count. In other words, manual payment attempts after the first attempt do not affect the retry schedule. If a failure is returned with a non-retryable return code, the invoice can no longer be retried unless a new payment method is obtained. Retries will continue to be scheduled, and attempt_count will continue to increment, but retries will only be executed if a new payment method is obtained.
 * @property bool $attempted Whether an attempt has been made to pay the invoice. An invoice is not attempted until 1 hour after the <code>invoice.created</code> webhook, for example, so you might not want to display that invoice as unpaid to your users.
 * @property null|bool $auto_advance Controls whether EDD\Vendor\Stripe performs <a href="https://stripe.com/docs/invoicing/integration/automatic-advancement-collection">automatic collection</a> of the invoice. If <code>false</code>, the invoice's state doesn't automatically advance without an explicit action.
 * @property \EDD\Vendor\Stripe\StripeObject $automatic_tax
 * @property null|int $automatically_finalizes_at The time when this invoice is currently scheduled to be automatically finalized. The field will be <code>null</code> if the invoice is not scheduled to finalize in the future. If the invoice is not in the draft state, this field will always be <code>null</code> - see <code>finalized_at</code> for the time when an already-finalized invoice was finalized.
 * @property null|string $billing_reason <p>Indicates the reason why the invoice was created.</p><p>* <code>manual</code>: Unrelated to a subscription, for example, created via the invoice editor. * <code>subscription</code>: No longer in use. Applies to subscriptions from before May 2018 where no distinction was made between updates, cycles, and thresholds. * <code>subscription_create</code>: A new subscription was created. * <code>subscription_cycle</code>: A subscription advanced into a new period. * <code>subscription_threshold</code>: A subscription reached a billing threshold. * <code>subscription_update</code>: A subscription was updated. * <code>upcoming</code>: Reserved for simulated invoices, per the upcoming invoice endpoint.</p>
 * @property null|string|\EDD\Vendor\Stripe\Charge $charge ID of the latest charge generated for this invoice, if any.
 * @property string $collection_method Either <code>charge_automatically</code>, or <code>send_invoice</code>. When charging automatically, EDD\Vendor\Stripe will attempt to pay this invoice using the default source attached to the customer. When sending an invoice, EDD\Vendor\Stripe will email this invoice to the customer with payment instructions.
 * @property int $created Time at which the object was created. Measured in seconds since the Unix epoch.
 * @property string $currency Three-letter <a href="https://www.iso.org/iso-4217-currency-codes.html">ISO currency code</a>, in lowercase. Must be a <a href="https://stripe.com/docs/currencies">supported currency</a>.

 * @property null|string $customer_phone The customer's phone number. Until the invoice is finalized, this field will equal <code>customer.phone</code>. Once the invoice is finalized, this field will no longer be updated.
 * @property null|\EDD\Vendor\Stripe\StripeObject $customer_shipping The customer's shipping information. Until the invoice is finalized, this field will equal <code>customer.shipping</code>. Once the invoice is finalized, this field will no longer be updated.

 * @property null|\EDD\Vendor\Stripe\StripeObject[] $customer_tax_ids The customer's tax IDs. Until the invoice is finalized, this field will contain the same tax IDs as <code>customer.tax_ids</code>. Once the invoice is finalized, this field will no longer be updated.
 * @property null|string|\EDD\Vendor\Stripe\PaymentMethod $default_payment_method ID of the default payment method for the invoice. It must belong to the customer associated with the invoice.

 * @property null|\EDD\Vendor\Stripe\StripeObject $metadata Set of <a href="https://stripe.com/docs/api/metadata">key-value pairs</a> that you can attach to an object. This can be useful for storing additional information about the object in a structured format.
