Rinne API Documentation

Transactions in rinne-js represent the checkout amount and context used by wallet elements during authorization. Create a new transaction whenever totals change so wallet sheets and backend charge requests stay aligned.

Create a Transaction

Use rinne.transaction.create() before mounting Apple Pay or Google Pay.

const transaction = await rinne.transaction.create({
  amount: 5000,
  currency: 'BRL',
  country: 'BR',
  lineItems: [
    { label: 'Subtotal', amount: 4500 },
    { label: 'Shipping', amount: 500 }
  ]
})

number

required

Amount in cents.

string

default:"BRL"

ISO 4217 currency code.

string

default:"BR"

ISO 3166 country code.

Array<{ label: string; amount: number }>

Optional line item breakdown used by wallet UIs.

Behavior Notes

The SDK initializes lazily on first transaction/element call.
currency defaults to BRL and country defaults to BR.
Returned transactions are intended to be passed into wallet elements.

Create a new transaction whenever checkout totals change. Keep the transaction amount aligned with what you charge on your backend.

Example with Dynamic Cart

const total = cartItems.reduce((sum, item) => sum + item.amount, 0)

const transaction = await rinne.transaction.create({
  amount: total,
  lineItems: cartItems.map((item) => ({
    label: item.label,
    amount: item.amount
  }))
})
