npm install @paystack/checkout-js --save
or just grab the js file and add it to your html directly
<script src="https://js.paystack.co/v1/checkout.js"></script>
import { Transaction } from 'checkout-js';
async function chargeCustomerCard() {
const transactionData = {
email: 'test@paystack.com', // replace this with customer email
amount: 100,
key: 'your_paystack_public_key',
};
try {
const transaction = await Transaction.request(transactionData);
await transaction.setCard({
number: '4084084084084081',
cvv: '408',
month: '01',
year: '20',
pin: '1234',
});
// charge resolves to a ChargeResponse
const chargeResponse = await transaction.chargeCard();
if (chargeResponse.status === 'success') {
console.log('card was charged successfully!');
}
} catch (error) {
console.log(error);
}
}
chargeCustomerCard();
Add the Checkout JS script to your HTML
document
<script src="https://js.paystack.co/v1/checkout.js"></script>
And then access the available classes in your JavaScript file;
var transactionData = {
email: 'test@paystack.com', // replace this with customer email

These are the classes exported by checkout js
:
The Transaction
class is the most important class in Checkout JS. All the functions required for initializing a transaction, updating it, and charging a customer using the supported payment channels are bound to this class.
For example, charging a customer's card could entail the following steps;
This is a grouping of the methods exported by the Transaction

const transactionData: Parameters = {
email: 'test@paystack.com', // replace this with the customer's email
amount: 100,
key: 'your_paystack_public_key',
};
// returns an instance of the Transaction class
const transaction = await Transaction.request(transactionData);
While the Transaction.request
method lets you create transactions from scratch in the browser, Transaction.requestWithAccessCode
lets you complete a transaction initialized from your server on the frontend. This method can be more secure and it, ensures no new transactions are created on the frontend.
Example
import { Transaction } from 'checkout-js';
const accessCode = 'ltxo947mrhrbz6z'; // Access code for transaction created on your server using the Paystack API
// returns an instance of the transaction class
const transaction = await Transaction.requestWithAccessCode(accessCode);
This is a utility method used to validate the parameters for requesting a new transaction.
Example
import { Transaction } from 'checkout-js';
const transactionData = {
email: 'test@paystack.com', // replace this with the customer's email
amount: 100,
key: 'your_paystack_public_key',
};
try {
Transaction.validate(transactionData); // throws validation errors
} catch (error) {
// handle validation errors thrown by Transaction.validate
}
NB: Transaction.request
calls this validation function implicitly, so you do not need to call it yourself except if you need to handle parameter validation separately.
For each attempt to charge a payment instrument, checkout-js
responds with a ChargeResponse
. This ChargeResponse
has the following interface depending on the kind of response received:
interface ChargeResponse {
status: string;
message: string;
data?: Object
errors?: Array;
}
reference will be made to this ChargeResponse
throughout the rest of the documentation. More details here
Charging a card includes the following steps:
This is an instance method on transactions to set a card to be charged for the transaction. With this, you can
Example
import { Transaction } from 'checkout-js';
const transactionData = { ... };
const transaction = await Transaction.request(transactionData)
interface Card {
number: string;
cvv: string;
month: string;
year: string;
}
/**
* Card number can have varying lengths, typically from 16 to 19 characters
* CVV can be 3 or 4 characters in length
*/
const newCard = {
number: '4084084084084081',
cvv: '408',
month: '01',
year: '20'
}
await transaction.setCard(newCard);
After setting a card on a transaction, you can now attempt to charge it by calling chargeCard()
Example
import { Transaction } from 'checkout-js';
...
const chargeResponse = await transaction.chargeCard();
If chargeResponse
returns a response with status ===
'auth'
you can request the customer's phone number or the OTP sent to their phone number. data.auth
on the chargeResponse
states what type of authentication is required.
Example
import { Transaction } from 'checkout-js';
const newCard = {
number: '4084084084084081',
cvv: '408',
month: '01',
year: '20'
}
await transaction.setCard(newCard);
...
let chargeResponse = await transaction.chargeCard();
if (chargeResponse.status === 'auth') {
let authResponse;
if (chargeResponse.data.auth === 'pin') {
// request customers phone number
newCard.pin = '1234'
await transaction.setCard(newCard)
chargeResponse = await transaction.chargeChard(); // attempt to charge the card again with the pin included
}
if (chargeResponse.data.auth === 'otp') {
// request otp sent to customer
const otp = '123456';
authResponse = await transaction.authenticateCard(otp); // returns a ChargeResponse
}
}
Use this function to wait for the response from the 3DS authentication from the customer. You’d need this if the charge response returns an auth type of 3ds
:
const chargeResponse = {
status: 'auth',
message: 'url-for-3ds-authentication',
data: {
auth: '3ds',
},
}
The callback function will be called with the response and a function to unsubscribe from pusher.
Example
const chargeResponse = await transaction.chargeCard();
...
function handleResponse(response, unsubscribe) {}
if (chargeResponse.status === 'auth') {
if (chargeResponse.data.auth === '3DS') {
// redirect customer to 3ds url in `chargeResponse.message`
// listen for response from 3ds authentication
listenFor3DSCharge(handleResponse);
}
}
To charge a bank account, you need to make sure it’s from one of the banks that Paystack supports bank payments from. To get a list of supported banks, call Toolkit.fetch('banks')
.
import { Toolkit } from 'checkout-js';
const banks = await Toolkit.fetch('banks');
// This will return an array of available banks like;
[
{
"name": "Access Bank",
"slug": "access-bank",
"code": "044",
"longcode": "044150149",
"gateway": "emandate",
"pay_with_bank": true,
"active": true,
"is_deleted": null,
"country": "Nigeria",
"currency": "NGN",
"type": "nuban",
"id": 1,
"createdAt": "2016-07-14T10:04:29.000Z",
"updatedAt": "2016-07-14T10:04:29.000Z"
},
{
"name": "Guaranty Trust Bank",
"slug": "guaranty-trust-bank",
"code": "058",
"longcode": "058152036",
"gateway": "ibank",
"pay_with_bank": true,
"active": true,
"is_deleted": null,
"country": "Nigeria",
"currency": "NGN",

"id": 9,
"createdAt": "2016-07-14T10:04:29.000Z",
"updatedAt": "2016-07-14T10:04:29.000Z"
},
...
]
checkout-js
currently handles three kinds of bank payments determined by the gateway
on the bank object. The gateways are emandate
, ibank
and digitalbankmandate
.
emandate
payments follow a “registration → verification → authentication” payment flow.ibank
payments require that your customers be redirected to their internet banking portal for authentication, after which they will be redirected back to your payment flow.digitalbankmandate
payments need to be authenticated with a phone number and a payId
Most banks use the emandate
flow while Guaranty Trust Bank and First Bank use the ibank
flow and Kuda Bank uses the digitalbankmandate
flow.
This method is used to fetch the internet banking url through which a customer can complete a transaction.
Example
...
const bank = {
...
bankId: 9,
name: 'Guaranty Trust Bank',
gateway: 'ibank',
...
};
await transaction.getIbankUrl(bank);
When the customer has been redirected to their internet banking portal to complete the transaction, you can wait for the final result using this function, passing a callback that will be called with the response and a function to unsubscribe from pusher
.
Example
...
// fetch internet banking URL
const url = await transaction.getIbankUrl(bank);
// redirect customer to internet banking portal
...
// listen for response from internet banking portal
function handleResponse(response, unsubscribe) {}
transaction.listenForIbankCharge(handleResponse);
// resolves to ChargeResponse
This function makes an attempt to charge a kuda bank account using the customer's phone number and a 6-digit payID
which the customer will generate from their kuda bank app
Example
...
const bank = {
...
id: 67,
name: 'Kuda Bank',
gateway: 'digitalbankmandate',
...
};
const phoneNumber = '07033773883'
const payId = 288299;
const params = {
phoneNumber,
bankId: bank.id,
payId
}
// resolves to ChargeResponse
await transaction.chargeDigitalBankMandate(params);
After calling the chargeDigitalBankMandate
function, you need to call the listenForDigitalBankMandateCharge
function to be notified of the status of the payment. This function accepts a callback
which will be called with the response as well as a function to unsubscribe from pusher — and a pusher_channel
, a property on data
gotten from the response to chargeDigitalBankMandate
.
const {
status,
message,
data
} = await transaction.chargeDigitalBankMandate(params);
function handleResponse(response, unsubscribe) {}
transaction.listenForDigitalBankMandateCharge(handleResponse, data.pusher_channel)
Sets the bank account the customer is going to use to complete the transaction.
Example
import { Transaction, Toolkit } from 'checkout-js';
...
const bank = {
...
id: 1,
name: 'Access Bank',
gateway: 'emandate',
type: 'nuban',
...
};
const bankAccount = {
bankId: bank.id,
accountType: bank.type,
accountNumber: '1234567890', // customer account number
}
await transaction.setBankAccount(bankAccount);
This method is responsible for charging the bank account that has been set on the transaction using transaction.setBankAccount()
.
Example
const chargeResponse = await transaction.chargeBankAccount();
// resolves to a ChargeResponse
Use this to register new customer bank accounts for e-mandate so they can be charged. You should do this if you get a response requiring birthday registration after attempting to charge a bank account with transaction.chargeBankAccount
.
{
status: 'auth',
message: 'This customer needs to register their account',
data: {
auth: 'birthday'
}
}
Example
...
await transaction.setbankAccount({...});
const chargeResponse = await transaction.chargeBankAccount();
if (chargeResponse.status === 'auth' && chargeResponse.data.auth === 'birthday') {
// pass the customer's birthday in the format 'dd-MM-yyyy'
const authResponse = await transaction.registerBankAccount('12-05-1980');
// resolves to a ChargeResponse
}
This method is used to authenticate bank transactions using an otp
.
Example
...
await transaction.setbankAccount({...});
const chargeResponse = await transaction.chargeBankAccount();
if (chargeResponse.status === 'auth' && chargeResponse.data.auth === 'otp') {
const authResponse = await transaction.authenticateBankAccount(123456);
// resolves to a ChargeResponse
}
The only available USSD channels for now are GTB’s 737, Sterling's 822, Zenith's 966 and UBA's 919
Use this to generate a USSD shortcode
Example
// initialize transaction
const response = await transaction.getUSSDShortcode({ channel: '919' });
// returns a response in the format
{
"status": true,
"message": "Offline Reference Generated Successfully",
"data": {
"reference": "887462",
"channel": "api_919_shortcode_00000",
"code": "*919*00*1*0000#"
}
}
Present the code in data.code
to your customers for payment.
Listen for when the customer completes the transaction via USSD. This function accepts a callback function to be called with the response and a function to unsubscribe from pusher.
Example
// initialize transaction
...
function handleResponse(response, unsubscribe) {}
transaction.listenForUSSDCharge({ channel: '919' }, handleResponse);
// return a ChargeResponse
The available QR channels are visa
in Nigeria and MPASS_OLTI
in South Africa .
Use this to generate a QR code
Example
// initialize transaction
const response = await transaction.getQRCode({ channel: 'visa' });
// returns a response in the format
{
"status": true,
"message": "QR successfully generated",
"data": {
"errors": false,
"url": "qr code image",
"qr_code": "qr code",
"status": "success",
"channel": "qr channel"
}
}
Display the QR code image in data.url
for your customers to scan.
Listen for when the customer has completed the transaction by scanning the QR code. This function accepts an object containing the QR channel
and a callback function to be called with the response and a function to unsubscribe from pusher.
Example
// initialize transaction
...
function handleResponse(response, unsubscribe) {}
transaction.listenForQRCharge({ channel: 'visa' }, handleResponse);
// return a ChargeResponse
This function is used to attempt a mobile money charge with a phoneNumber
, a provider
and optionally, a voucher
and a registrationToken

"provider": "VOD",
"channel_name": "MOBILE_MONEY_2",
"display": {
"type": "voucher",
"message": "Please enter your voucher code to complete this payment"
}
}
}
/**
* Depending on what the `display.type` is from the previous response, you might
* need to collect additional information to complete the payment
*/
/**
* If you get a `display.type === voucher`, collect a voucher from the customer
* and call chargeMobileMoney again, this time including the voucher as one of the
* arguments
*/
const response = await transaction.chargeMobileMoney(
{
phoneNumber: '05012345678',
provider: 'VOD',
voucher: 'voucher-code'
}
);
/**
* If you get a `display.type === registration_token`, collect a registrationToken from the customer
* and call chargeMobileMoney again, this time including the registrationToken
* as one of the arguments
*/
const response = await transaction.chargeMobileMoney(
{
phoneNumber: '05012345678',
provider: 'VOD',
registrationToken: 'token'
}
);
/**
* The `registrationToken` phase should be the last stage in the process after
* which you should start listening for a response as stated in the next section
*/
Listen for when the customer has completed the payment, passing a callback function to be called with the response and a function to unsubscribe from pusher.
Example
// initialize transaction
...
function handleResponse(response, unsubscribe) {}
transaction.listenForQRCharge(handleResponse);
// return a ChargeResponse

This is the format in which all charge responses in checkout-js
are returned. A charge response will always have a status
and a message
.
This means that the charge attempt was successful
Example
{
status: 'success',
message: 'Transaction successful',
data: { ... }
}
This means that additional authentication has to be carried out to complete the transaction

status: 'auth',
message: 'Authentication Required', // for 3DS, this would be the 3DS redirect URL
data: {
auth: 'pin' // can either be [pin, otp or 3DS]
}
}
This means that the charge attempt failed

{
status: 'failed',
message: 'Transaction failed',
errors: [],
/* the 'error' object is only available if a card transaction fails. It tells us the bank the failed card was issued by. You can use this to suggest that your customer pays with their bank account, if it's one of the supported banks in Toolkit.fetch('banks') */

This library uses a third party service, Pusher, to listen for API responses in the following methods
Transaction.listenFor3DSCharge
Transaction.listenForIbankCharge
Transaction.listenForUSSDCharge
Transaction.listenForQRCharge
Transaction.listenForMobileMoneyCharge
Transaction.listenForDigitalBankMandateCharge
However, this does not work on non-Paystack domains so you have to use the transaction.requery()
method to check the status of the transaction when using any of those payment methods.
To ensure higher success rates, errors and failure messages should not be taken as an indication of finality, for example when a payment fails on the Paystack Checkout, the customer is prompted to retry via the same payment method or an alternative payment method.
