Create a wallet session

Overview

Manages authentication and creates wallet elements.

The WalletSession handles token management, element creation, and provides convenience methods for showing wallet elements in modals.

For v1, mint the token via the existing whop.accessTokens.create({ company_id }) flow — the same backend mutation that powers PayoutsSession. No new mutation is required.

Examples

Basic usage

const session = whopElements.createWalletSession({
  companyId: "biz_xxx",
  token: async () => {
    const response = await fetch("/api/wallet-token");
    const data = await response.json();
    return data.token;
  },
});
session.on("ready", () => {
  console.log("Wallet session is ready");
});

Options

Property	Type	Required	Default	Description
`token`	`Token \| GetToken`	Yes	-	The token to use for the session. If a function is provided, it will be called and awaited to get the token. When a function is provided, the token will be refreshed automatically before it expires. if a string is provided, it will be used as the token and not refreshed automatically. However you can update the token at runtime by calling ‘updateOptions’ with a new token. For v1, mint this token from your backend with the existing ‘whop.accessTokens.create({ company_id })’ call — the same approach used by ‘PayoutsSession’. A dedicated ‘wallet:*’ scope set is on the roadmap.
`companyId`	`string`	Yes	-	The company ID that owns the wallet. Accepts a ‘biz_*’ ID. The wallet’s underlying ledger account is resolved server-side from this value. (A polymorphic ‘ledger_account_id’ parameter is on the roadmap once ‘wallet:session:create’ ships.)
`currency`	`string \| undefined`	No	”USD”	The currency to format display amounts in.

Events

Events emitted by the WalletSession.

Listen to these events using the on() method.

`optionsUpdated`

Emitted when the session options are updated via updateOptions().

Callback signature: (options: ExpandedWalletSessionOptions) => void

`tokenRefreshed`

Emitted when the authentication token is refreshed.

Callback signature: (token: string) => void

`tokenRefreshError`

Emitted when token refresh fails.

Callback signature: (error: unknown) => void

`error`

Emitted when an error occurs during session operation.

Callback signature: (error: unknown) => void

`ready`

Emitted when the session is ready and authenticated.

Callback signature: (void) => void

Methods

`createElement(type, options)`

Create a new element instance.

Parameter	Type	Description
`type`	T \| { type: T; }	The element type
`options`	WalletSessionElements[T] extends [infer O, unknown] ? O : never	Element-specific configuration options

Returns: WalletSessionElements[T] extends [unknown, infer E] ? E : never

`updateOptions(options)`

Update the session options after initialization.

Changes will be propagated to all active elements.

Parameter	Type	Description
`options`	Partial<WalletSessionOptions>	Partial options object with the values to update

`destroy()`

Destroy the session and clean up all mounted elements.

Call this when you no longer need the session to free up resources.
