/**
* @class
* @param {object} options see {@link module:braintree-web/paypal-checkout.create|paypal-checkout.create}
* @classdesc This class represents a PayPal Checkout component that coordinates with the {@link https://developer.paypal.com/docs/checkout/integrate/#2-add-the-paypal-script-to-your-web-page|PayPal SDK}. Instances of this class can generate payment data and tokenize authorized payments.
*
* All UI (such as preventing actions on the parent page while authentication is in progress) is managed by the {@link https://developer.paypal.com/docs/checkout/integrate/#2-add-the-paypal-script-to-your-web-page|PayPal SDK}. You must provide your PayPal `client-id` as a query parameter. You can [retrieve this value from the PayPal Dashboard](https://developer.paypal.com/docs/checkout/integrate/#1-get-paypal-rest-api-credentials).
* @description <strong>Do not use this constructor directly. Use {@link module:braintree-web/paypal-checkout.create|braintree-web.paypal-checkout.create} instead.</strong>
*
* #### Integrate Checkout Flow with PayPal SDK
*
* You must have [PayPal's script, configured with various query parameters](https://developer.paypal.com/docs/checkout/integrate/#2-add-the-paypal-script-to-your-web-page), loaded on your page:
*
* ```html
* <script src="https://www.paypal.com/sdk/js?client-id=your-sandbox-or-prod-client-id"></script>
* <div id="paypal-button"></div>
* ```
*
* When passing values in the `createPayment` method, make sure they match the [corresponding parameters in the query parameters for the PayPal SDK script](https://developer.paypal.com/docs/checkout/reference/customize-sdk/).
*
* ```javascript
* braintree.client.create({
* authorization: 'authorization'
* }).then(function (clientInstance) {
* return braintree.paypalCheckout.create({
* client: clientInstance
* });
* }).then(function (paypalCheckoutInstance) {
* return paypal.Buttons({
* createOrder: function () {
* return paypalCheckoutInstance.createPayment({
* flow: 'checkout',
* currency: 'USD',
* amount: '10.00',
* intent: 'capture' // this value must either be `capture` or match the intent passed into the PayPal SDK intent query parameter
* // your other createPayment options here
* });
* },
*
* onApprove: function (data, actions) {
* // some logic here before tokenization happens below
* return paypalCheckoutInstance.tokenizePayment(data).then(function (payload) {
* // Submit payload.nonce to your server
* });
* },
*
* onCancel: function () {
* // handle case where user cancels
* },
*
* onError: function (err) {
* // handle case where error occurs
* }
* }).render('#paypal-button');
* }).catch(function (err) {
* console.error('Error!', err);
* });
* ```
*
* #### Integrate Vault Flow with PayPal SDK
*
* You must have [PayPal's script, configured with various query parameters](https://developer.paypal.com/docs/checkout/integrate/#2-add-the-paypal-script-to-your-web-page), loaded on your page:
*
* ```html
* <script src="https://www.paypal.com/sdk/js?client-id=your-sandbox-or-prod-client-id&vault=true"></script>
* <div id="paypal-button"></div>
* ```
*
* When passing values in the `createPayment` method, make sure they match the [corresponding parameters in the query parameters for the PayPal SDK script](https://developer.paypal.com/docs/checkout/reference/customize-sdk/).
*
* ```javascript
* braintree.client.create({
* authorization: 'authorization'
* }).then(function (clientInstance) {
* return braintree.paypalCheckout.create({
* client: clientInstance
* });
* }).then(function (paypalCheckoutInstance) {
* return paypal.Buttons({
* createBillingAgreement: function () {
* return paypalCheckoutInstance.createPayment({
* flow: 'vault'
* // your other createPayment options here
* });
* },
*
* onApprove: function (data, actions) {
* // some logic here before tokenization happens below
* return paypalCheckoutInstance.tokenizePayment(data).then(function (payload) {
* // Submit payload.nonce to your server
* });
* },
*
* onCancel: function () {
* // handle case where user cancels
* },
*
* onError: function (err) {
* // handle case where error occurs
* }
* }).render('#paypal-button');
* }).catch(function (err) {
* console.error('Error!', err);
* });
* ```
*
* #### Integrate with Checkout.js (deprecated PayPal SDK)
*
* If you are creating a new PayPal integration, please follow the previous integration guide to use the current version of the PayPal SDK. Use this integration guide only as a reference if you are already integrated with Checkout.js.
*
* You must have PayPal's Checkout.js script loaded on your page.
*
* ```html
* <script src="https://www.paypalobjects.com/api/checkout.js" data-version-4 log-level="warn"></script>
* ```
*
* ```javascript
* braintree.client.create({
* authorization: 'authorization'
* }).then(function (clientInstance) {
* return braintree.paypalCheckout.create({
* client: clientInstance
* });
* }).then(function (paypalCheckoutInstance) {
* return paypal.Button.render({
* env: 'production', // or 'sandbox'
*
* payment: function () {
* return paypalCheckoutInstance.createPayment({
* // your createPayment options here
* });
* },
*
* onAuthorize: function (data, actions) {
* // some logic here before tokenization happens below
* return paypalCheckoutInstance.tokenizePayment(data).then(function (payload) {

* Initializes the PayPal checkout flow with a payment method nonce that represents a vaulted PayPal account.

* @param {object} options These options are identical to the {@link PayPalCheckout#createPayment|options for creating a payment resource}, except for the following:
* * `flow` cannot be set (will always be `'checkout'`)
* * `amount`, `currency`, and `vaultInitiatedCheckoutPaymentMethodToken` are required instead of optional
* * Additional configuration is available (listed below)
* @param {boolean} [options.optOutOfModalBackdrop=false] By default, the webpage will darken and become unusable while the PayPal window is open. For full control of the UI, pass `true` for this option.
* @param {callback} [callback] The second argument, <code>payload</code>, is a {@link PayPalCheckout~tokenizePayload|tokenizePayload}. If no callback is provided, the promise resolves with a {@link PayPalCheckout~tokenizePayload|tokenizePayload}.
* @example
* paypalCheckoutInstance.startVaultInitiatedCheckout({

For a full list of query params, see the [PayPal docs](https://developer.paypal.com/docs/checkout/reference/customize-sdk/?mark=query#query-parameters).
* @param {string} [options.client-id] By default, this will be the client id associated with the authorization used to create the Braintree component. When used in conjunction with passing `authorization` when creating the PayPal Checkout component, you can speed up the loading of the PayPal SDK.
* @param {string} [options.intent="authorize"] By default, the PayPal SDK defaults to an intent of `capture`. Since the default intent when calling {@link PayPalCheckout#createPayment|`createPayment`} is `authorize`, the PayPal SDK will be loaded with `intent=authorize`. If you wish to use a different intent when calling {@link PayPalCheckout#createPayment|`createPayment`}, make sure it matches here. If `sale` is used, it will be converted to `capture` for the PayPal SDK. If the `vault: true` param is used, `tokenize` will be passed as the default intent.
* @param {string} [options.locale=en_US] Use this option to change the language, links, and terminology used in the PayPal flow. This locale will be used unless the buyer has set a preferred locale for their account. If an unsupported locale is supplied, a fallback locale (determined by buyer preference or browser data) will be used and no error will be thrown.
*
* Supported locales are:
* `da_DK`,
* `de_DE`,
* `en_AU`,
* `en_GB`,
* `en_US`,
* `es_ES`,
* `fr_CA`,
* `fr_FR`,
* `id_ID`,
* `it_IT`,
* `ja_JP`,
* `ko_KR`,
* `nl_NL`,
* `no_NO`,
* `pl_PL`,
* `pt_BR`,
* `pt_PT`,
* `ru_RU`,
* `sv_SE`,
* `th_TH`,
* `zh_CN`,
* `zh_HK`,
* and `zh_TW`.
*
* @param {string} [options.currency="USD"] If a currency is passed in {@link PayPalCheckout#createPayment|`createPayment`}, it must match the currency passed here.
* @param {boolean} [options.vault] Must be `true` when using `flow: vault` in {@link PayPalCheckout#createPayment|`createPayment`}.
* @param {string} [options.components=buttons] By default, the Braintree SDK will only load the PayPal smart buttons component. If you would like to load just the [messages component](https://developer.paypal.com/docs/business/checkout/add-capabilities/credit-messaging/), pass `messages`. If you would like to load both, pass `buttons,messages`
* @param {object} [options.dataAttributes] The data attributes to apply to the script. Any data attribute can be passed. A subset of the parameters are listed below. For a full list of data attributes, see the [PayPal docs](https://developer.paypal.com/docs/checkout/reference/customize-sdk/#script-parameters).
* @param {string} [options.dataAttributes.client-token] The client token to use in the script. (usually not needed)
* @param {string} [options.dataAttributes.csp-nonce] See the [PayPal docs about content security nonces](https://developer.paypal.com/docs/checkout/reference/customize-sdk/#csp-nonce).
