React Native SDK(v3) - Checkout

Please follow steps below to setup React Native SDK and start accepting payment via CHAIPort.

For initial SDK installation set up refer here

React Native Payment SDK v3#

Included the SDK checkout UI in the Mobile SDK.

  1. Import the library as below:
import Checkout from 'chaiport-sdk';
  1. Initialize the checkout instance as below:
env={"dev"} //Optional
secretKey={SECRET_KEY} // Secret Key
chaipayKey={CHAIPAY_KEY} // chaipay key
  1. Create the reference for checkout
constructor(props) {
this.checkout = React.createRef();

To create the payment link, generate the JWT token

Generate the JWT token:

  • create the JWT token using the payload and chaipay secretKey
    • payload:
      var payload = {
      iss: 'CHAIPAY',
      sub: 'lzrYFPfyMLROallZ',
      iat: new Date().getTime(),
      exp: new Date().getTime() + 100 * 1000,
      // Secret key of your domain
      var secretKey =
  • Algorithm to use for generating token - “HS256”

To get the payment link to use the SDK checkout UI, call the openCheckoutUI method from SDK as below:

this.checkout.current.openCheckoutUI(config, jwtToken);

let payload = {

  • Web view response will be given back to the callbackFunction
afterCheckout = transactionDetails => {
console.log('Response from webview', transactionDetails);
// Do the needful
