Mounts inside Payments. Pass props and callbacks through the create options or React props. Keep the created handle, or React ref, to call validate() and getValues().
Mounts inside a WhopPayments scope. Collects the billing address in the selected country’s own format, and the controller reads it for the mint whether or not you bind it.
Mount inside <Payments>, which owns the charge and the confirmation token. <Payments> itself mounts inside <WhopElements>. It renders the billing address in the buyer’s own country format and publishes it to the provider, so createConfirmationToken picks it up without being passed anything.

Example data. Open the Playground.

Props

"never" | "toggle" | "always"
Address line 2: always visible (default), revealed by a text button (toggle), or never collected. Defaults to "always".
"split" | "combined" | "none"
The name row: one full-name field (default), split first/last fields, or none. Defaults to "combined".
"full" | "compact"
full (default) stacks labeled fields. compact groups placeholder-labeled fields within one border. Defaults to "full".
"billing" | "shipping"
Browser autocomplete purpose: billing (default) or shipping. Defaults to "billing".
"full" | "minimal"
full (default) follows the selected country’s complete address format. minimal collects only country and postal code. name independently adds required name fields. Set name to none to omit them. This element does not add fields required by a payment method. Card confirmation requires a name, country, and postal code, so keep name enabled or pass billingDetails.name. Defaults to "full".
"name" | "none" | "name_with_type"
Organization fields: none (default), name only, or name with a business/individual selector. Defaults to "none".
{ name?: string | undefined; address?: { name?: string | undefined; first_name?: string | undefined; last_name?: string | undefined; organization?: string | undefined; organization_type?: "business" | "individual" | undefined; line1?: string | undefined; line2?: string | undefined; city?: string | undefined; state?: string | undefined; postal_code?: string | undefined; country?: string | undefined; } | undefined; }
Seed values applied once before first paint (address.country is an ISO 3166-1 alpha-2 country code). Takes precedence over IP-country detection.
boolean
Default the country from the buyer’s IP (resolved before first paint). Falls back to the controller’s countryHint, then US. Defaults to true.
string[]
Allowed ISO 3166-1 alpha-2 country codes. With one code, the selector remains visible but offers only that country.
boolean
Enables Google Places suggestions for the street address. If no match appears or Places is blocked, the list reports no matches and lets buyers enter the address manually. Set false for a plain input. Defaults to true.
({ key: string; label: string; type: "text" | "select" | "phone" | "date"; position: "after_name" | "after_organization" | "before_country" | "after_address"; required?: boolean | undefined; options?: string[] | undefined; format?: string | undefined; autocomplete?: string | undefined; })[]
Additional fields rendered with the address form. Values are validated and emitted in the separate custom map.
string
Fallback country after defaultValues and IP detection. Use an ISO 3166-1 alpha-2 code. An empty value falls back to US. Defaults to "".

Events

Pass callbacks in the create options or React props.

onChange

Fires when the address changes. complete is true when all country-specific fields and required custom fields are valid. address follows confirmation-token billing_details names, including postal_code. country is an ISO 3166-1 alpha-2 code. Custom values are in custom.Signature: ((payload: { complete: boolean; address: { name?: string | undefined; first_name?: string | undefined; last_name?: string | undefined; organization?: string | undefined; organization_type?: "business" | "individual" | undefined; line1?: string | undefined; line2?: string | undefined; city?: string | undefined; state?: string | undefined; postal_code?: string | undefined; country: string; }; custom: Record<string, string>; }) => void)

onLoaderStart

Runs after the loading skeleton first paints and before onReady.Signature: (() => void)

onReady

Runs after the element’s first complete paint.Signature: (() => void)

onError

Runs when the element fails to load or crashes. The fallback remains visible. Use code for programmatic handling. sourceKey identifies a failed host-state source.Signature: ((e: { message: string; code?: string | undefined; sourceKey?: string | undefined; }) => void)

Methods

Call these on the handle returned by create, or through a React ref.

validate

Validates the form, reveals all inline errors, and never throws. Returns complete, address, and errors. errors is empty exactly when complete is true. Keys use contract names such as postal_code and line1, custom:<key> for custom fields, and transient form while loading.Signature: () => Promise<{ complete: boolean; address: { name?: string | undefined; first_name?: string | undefined; last_name?: string | undefined; organization?: string | undefined; organization_type?: "business" | "individual" | undefined; line1?: string | undefined; line2?: string | undefined; city?: string | undefined; state?: string | undefined; postal_code?: string | undefined; country: string; }; errors: Record<string, string>; }>

getValues

Returns address and custom without validation or revealing errors.Signature: () => Promise<{ address: { name?: string | undefined; first_name?: string | undefined; last_name?: string | undefined; organization?: string | undefined; organization_type?: "business" | "individual" | undefined; line1?: string | undefined; line2?: string | undefined; city?: string | undefined; state?: string | undefined; postal_code?: string | undefined; country: string; }; custom: Record<string, string>; }>

mount

Mounts the element in target and starts loading. React components mount themselves.Signature: (target: string | HTMLElement) => void

destroy

Removes the element and releases its frame and subscriptions. You can call it more than once. React removes the element automatically.Signature: () => void

update

Merges new props into the mounted element. In React, change the component props instead.Signature: (options: Partial<AddressElementProps>) => void

Styling

Style these parts through appearance.classes. Use camel case or kebab case for property names and include units. Page stylesheets can’t reach the element’s frame. The framework validates each declaration before injecting it.
In React, pass appearance to <Payments>. Set it globally with WhopElements({ appearance }).

Parameters

Binding<PostalAddress>?
Reads the collected address back out. The controller collects it either way.
Binding<Bool>?
True once every field the country requires is filled and valid.
WhopAddressElement.Mode
.billing or .shipping. Shipping asks the keyboard for shipping fields. Defaults to .billing.
WhopAddressElement.Layout
.full labels every field and stacks them; .compact moves the labels into placeholders. Defaults to .full.
WhopAddressElement.Scope
.full collects the country’s whole format; .minimal collects country and postal code only. Defaults to .full.
WhopAddressElement.NameFields
.combined for one full-name field, .split for first and last, .none to leave the name out. Defaults to .combined.
WhopAddressElement.OrganizationFields
.none, .name for an organization name, or .nameWithType to also ask whether it is a business or an individual. Defaults to .none.
WhopAddressElement.Line2Field
.always shows the second line, .toggle reveals it with a button, .never leaves it out. Defaults to .toggle.
PostalAddress?
Values to start from. Its country is an ISO 3166-1 alpha-2 code and takes precedence over detection.
Bool
Starts on the buyer’s own country when true. Falls back to countryHint, then the charge currency’s country, then US. Defaults to true.
[String]?
Restricts the picker to these ISO 3166-1 alpha-2 codes, intersected with the selected method’s own constraint.
String?
ISO 3166-1 alpha-2 fallback for the country chain.
Bool
Street suggestions as the buyer types. With it off there is nothing to pick, so every field shows from the start. Defaults to true.

PostalAddress

What a selection hands back:
  • country: String: ISO 3166-1 alpha-2, uppercased
  • line1 / line2 / city / state / postalCode: String?, in the country’s own format
  • name / firstName / lastName: String?, per the name mode
  • organization / organizationType: String?, per the organization mode

States

The form renders immediately. With autocomplete on at .full scope, the locality fields appear after a suggestion or a manual entry; turn it off and every field shows at once. Errors reveal on the first confirm attempt, then live.

Good to know

  • MapKit provides the street suggestions on-device. Whop never sees the buyer’s query as they type.
  • defaultValues.country beats detection. Detection falls back to countryHint, then the charge currency’s country, then US.
  • allowedCountries is intersected with the selected method’s own billing-country constraint, so a method that only takes one country narrows the picker on its own.
  • PostalAddress uses the confirmation-token billing_details keys, so the same JSON works across platforms.

Install

Mount it inside a WhopPayments(accountID:charge:) scope, which creates the controller and hands it to its content. payments.buyer is the signed-in buyer once an email sign-in has proven one. WhopBrandingElement has to be on screen too, because Whop is merchant of record on these sales and createConfirmationToken refuses without it. Style with .whopElementsAppearance(_:). The module is Elements, not the wallet SDK’s WhopElements. See Getting started and Appearance.

Props

'billing' | 'shipping'
Autocomplete purpose. Defaults to billing.
'full' | 'compact'
full labels every field and stacks them. compact moves the labels into placeholders. Defaults to full.
'full' | 'minimal'
full follows the country’s complete format. minimal collects country and postal code only. Defaults to full.
'combined' | 'split' | 'none'
One full-name field, first and last, or no name field. Defaults to combined.
'none' | 'name' | 'name_with_type'
Whether to collect an organization, and whether to also ask if it is a business or an individual. Defaults to none.
'toggle' | 'always' | 'never'
How the second address line appears. Defaults to toggle, which shows an “Add address line 2” button.
string[]
Restrict the country selector to these ISO 3166-1 alpha-2 codes. A selected payment method’s own country list narrows this further, never widens it.
boolean
Default the country from the buyer’s IP.
string
Fallback country after defaultValues and IP detection. ISO 3166-1 alpha-2.
{ name?: string; address?: Partial<EmittedAddress> }
Seed values applied once at mount, for a resumed session.
CustomFieldSpec[]
Extra fields rendered at a declared position (after_name, after_organization, before_country, after_address). A required one gates complete.
(payload: AddressChangePayload) => void
Fires on every edit with the current snapshot.
StyleProp<ViewStyle>
Applied to the element’s outer View. For theming, prefer appearance.parts on the provider, which covers every element on this surface. Note the React Native part names are their own set today, not the web’s whop-* class names, so a web appearance object does not port across unchanged.
ReactNode
Rendered instead of the built-in skeleton while the element loads.
() => void
Fires once the element is interactive. <Payments> groups these, so its own onLoadingChange is usually the one you want.
(error: { message: string; code?: string }) => void
A load or configuration failure for this element. The element renders its own error face either way.

AddressChangePayload

What onChange hands back:
  • complete: boolean: every field the country requires is filled and valid
  • address: EmittedAddress: what the buyer has entered so far
  • custom: Record<string, string>: values for any customFields you declared

States

A three-field skeleton while the country catalog loads, then the form. Changing the country re-plans the fields, because the format is the country’s, not a fixed set. onChange reports complete when every field the country requires is filled and valid.

Good to know

  • The country defaults from the buyer’s IP when detectCountry is on, then countryHint, then US. defaultValues.address.country overrides all three.
  • autocomplete is on by default, as on web, but it is served by the platform geocoder rather than Google Places, so it needs no API key, no account and no extra dependency. iOS uses MKLocalSearchCompleter, a real as-you-type API that answers a fragment with several candidates. Android uses android.location.Geocoder, which resolves a complete address rather than predicting from a partial one: expect roughly one result, and a coarser one on a half-typed street. Android ships no keyless typeahead, and the alternative — the Places SDK — would add several megabytes and force location permissions on every app embedding this SDK.
  • Either platform falling short is silent by design: a geocoder with no backend, no network or no matches shows nothing and the buyer types the address by hand, which is where they started. Autocomplete never blocks a checkout.
  • The emitted address uses the same keys as the web element and the confirmation token’s billing_details, so one payload shape works across platforms.
  • A mounted address element is the provider’s billing source. Unmount it and createConfirmationToken falls back to whatever you pass it directly.
Wrap your app in <WhopElements getToken={…}> once, then mount <Payments> around the elements. See Getting started and Appearance.
