JS

To customize your payments experience

This section covers different methods and their params of the Hyperswitch JS SDK

Hyperswitch's JS SDK come with many methods which you can use to customize your payments experience. You can use the props to change the appearance, reorder payment methods and much more to suit your business needs.

Hyper()

This constructor gives you access to methods in Hyper API, which you can call. The API details are listed down below.

let hyper = Hyper();

1. hyper.confirmPayment(options)

Use hyper.confirmPayment to confirm a PaymentIntent using data collected by the Payment Element. When called, hyper.confirmPayment will attempt to complete any required actions, such as authenticating your user by displaying a 3DS dialog or redirecting them to a bank authorization page. Your user will be redirected to the return_url you pass once the confirmation is complete.

options (Required)	Description
elements (object)	Required. The Elements instance that was used to create the Payment Element.
confirmParams (object)	Parameters that will be passed on to the Hyper API.
redirect (string)	Can be either 'always' or 'if_required' By default, hyper.confirmPayment will always redirect to your return_url after a successful confirmation. If you set redirect: "if_required", then hyper.confirmPayment will only redirect if your user chooses a redirect-based payment method.

ConfirmParams object

confirmParams	Description
return_url(string)	Required. The url your customer will be directed to after they complete payment.

2. hyper.elements(options)

This method creates an Elements instance, which manages a group of elements.

options (Required)	Description
font (array)	An array of custom fonts, which elements created from the Elements object can use. Fonts can be specified as CssFontSource or CustomFontSource objects.
locale (string)	A locale to display placeholders and error strings in. Default is auto (HyperSwitch detects the locale of the browser).

clientSecret is a required string.

elements()

After calling the hyper.elements with your options, you will get access to the Elements API. This will have methods which are not specific to a particular payment element (UnifiedCheckout, HyperWidgets, etc. ) but are needed for the overall operation of them.

let elements = hyper.elements(options);

1. elements.getElement(type)

This method retrieves a previously created Payment Element. Here the type is payment for Unified Checkout.

elements.getElement('payment') returns one of the following:

• An instance of a Unified Checkout.

• null, when no Unified Checkout has been created.

2. elements.create(type, options?)

This method creates an instance of an individual Element. It takes the type of Element to create as well as an options object.

The type can be ‘payment’ for UnifiedCheckout.

Options object

options (Required)	Description
layout (accordion/tabs/objects)	Specify the layout for the Payment Element. If you only pass a layout type ('accordion' or ‘tabs’) without any additional parameters, the Payment Element renders using that layout and the default values associated with it. An object can also be passed to specify the layout with additional configuration.
defaultValues (object)	Provide initial customer information that will be displayed in the Payment Element. The form will render with empty fields if not provided.
business (object)	Provide information about your business that will be displayed in the Payment Element. This object contains a key value pair of name which is a string
paymentMethodOrder (array)	By default, the Payment Element will use a dynamic ordering that optimizes payment method display for each user. You can override the default order in which payment methods are displayed in the Payment Element with a list of payment method types. If the associated PaymentIntent has payment method types not specified in paymentMethodOrder, they will be displayed after the payment methods you specify. If you specify payment method types not on the associated PaymentIntent, they will be ignored.
fields (object)	By default, the Payment Element will collect all necessary details to complete a payment. For some payment methods, this means that the Payment Element will collect details like name or email that you may have already collected from the user. If this is the case, you can prevent the Payment Element from collecting these data by using the fields option. If you disable the collection of a certain field with the fields option, you must pass that same data to hyper.confirmPayment or the payment will be rejected.
terms (object)	Control how mandates or other legal agreements are displayed in the Payment Element. Use never to never display legal agreements. The default setting is auto, which causes legal agreements to only be shown when necessary.
wallets (object)	By default, the Payment Element will display all the payment methods that the underlying Payment Intent was created with. However, wallets like Apple Pay and Google Pay are not payment methods per the Payment Intent API. They will show when the Payment Intent has the card payment method and the customer is using a supported platform and have an active card in their account. This is the auto behavior, and it is the default for choice for all wallets. If you do not want to show a given wallet as a payment option, you can set its property in wallets to never.

Layout object

layout	Description
type (accordion/tabs)	Defines the layout to render the Payment Element.
defaultCollapsed (boolean)	Controls if the Payment Element renders in a collapsed state (where no payment method is selected by default). When you leave this undefined, Hyperswitch renders the experience that it determines will have the best conversion.
radios (boolean)	Renders each Payment Method with a radio input next to its logo. The radios visually indicate the current selection of the Payment Element. This property is only applicable to the accordion layout.
spacedAccordionItems (boolean)	When true, the Payment Methods render as standalone buttons with space in between them. This property is only applicable to the accordion layout.
visibleAccordionItemsCount (number)	Sets the max number of Payment Methods visible before using the "More" button to hide additional Payment Methods. Set this value to 0 to disable the "More" button and render all available Payment Methods. Default is 5. This property is only applicable to the accordion layout.

defaultValues object

defaultValues	Description
billingDetails (object)	Specify customer's billing details, which lets you pre-fill a customer’s name, email, phone number and address if required by payment method. Pre-filling as much information as possible streamlines the checkout process.

billingDetails	Description
name (string)
email (string)
phone (string)
address (object)

line2 (string)
city (string)
state (object)

style (object)	This gives the style to the wallet buttons in the Payment Element.

3. elements.update(options)

Updates the options the Element was initialized with. Updates are merged into the existing configuration.

If you collect certain information in a different part of your interface (e.g., ZIP or postal code), use element.update with the appropriate information.

The styles of an Element can be dynamically changed using element.update. This method can be used to simulate CSS media queries that automatically adjust the size of elements when viewed on different devices

options	Description
locale (string)	A locale to display placeholders and error strings in. Default is auto (Hyperswitch detects the locale of the browser).Setting the locale does not affect the behavior of postal code validation—a valid postal code for the billing country of the card is still required.
appearance (object)	Supported for the Unified CheckoutMatch the design of your site with the appearance option. The layout of each Element stays consistent, but you can modify colors, fonts, borders, padding, and more.
clientSecret (string)	Required to use with the Unified Checkout and the Hyper WidgetsThe client secret for a PaymentIntent

paymentElement()

After calling the elements.create with your type and options, you will get access to the PaymentElements API. This will provide you the exact Payment Element you want (UnifiedCheckout, CardElement, etc. ) and functions attached to it by which you can perform various operations

let paymentElement = elements.create("payment",options);

1. paymentElement.mount(domElement)

This method attaches your Payment Element to the DOM. This only accepts a CSS seletor (eg, #unified-checkout) . You need to have created a DOM element in your HTML file where you think you can mount the Payment Element.

2. paymentElement.blur()

Blurs the Payment Element.

3. paymentElement.clear()

Clears the values of the Payment Element.

4. paymentElement.destroy()

Removes the Payment Element from the DOM and destroys it. A destroyed Element cannot be re-mounted to the DOM.

5. paymentElement.focus()

Focuses the Payment Element fields.

6. paymentElement.unmount()

Unmounts the Payment Element from the DOM. Call paymentElement.mount to re-attach it to the DOM.

7. paymentElement.update(options)

Updates the options the Payment Element was initialized with. Updates are merged into the existing configuration. This uses the same API as elements.create().

8. paymentElement.on(type, handler)
