Usage

Creating a Payment Session

To be able to initiate the payment process, you must create a new payment session.

// 1- create a new payment session
type CreateSessionParams = {
  apiHost: string // host of your Accept NANO server, without protocol
  pollInterval?: number // time interval (ms) to re-check for verification of a payment (default: 3s)
  debug?: boolean // enables debug mode and prints some useful stuff to console
}

const session = acceptNano.createSession({
  apiHost: 'accept-nano-demo.put.io',
})

// 2- register event listeners to shape-up your logic based on session events.
type PaymentSessionEvents = {
  start: () => void
  end: (error: PaymentError | null, payment: AcceptNanoPayment | null) => void
}

session.on('start', () => {
  myApp.paymentStarted()
})

session.on('end', (error, payment) => {
  if (error) {
    return myApp.paymentFailed({ reason: error.reason })
  }

  return myApp.paymentSucceeded({
    amount: payment.amount,
    state: payment.state,
  })
})

Presenting the Payment Overlay

After creating your session and attaching the event listeners, you can follow one of those options to proceed with the payment flow.

Option 1: Create a Payment Through Client

If you want to create and verify an accept-nano payment in your client application, you can use this option.

After the payment is created, accept-nano-client will automatically proceed to the verification step.

type CreatePaymentParams = {
  amount: string // stringified number
  currency: 'NANO' | 'USD'
  state?: string // payload to share between your client and server, will be embedded into the payment object
}

session.createPayment({
  amount: '1',
  currency: 'USD',
  state: '{userId:7}',
})

Option 2: Verify a Payment Through Client

If you create an accept-nano payment in another context (such as your application's backend), you can use this option to perform the verification in your client application.

type VerifyPaymentParams = {
  token: string // the Accept NANO payment token created in your backend application
}

session.verifyPayment({ token: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9' })
