Create a session to pay with a card

SDK v1
Coming soon

Use our React Native SDK to secure your customer's card details by creating a session.

Full sample integration: You can see an example of the session generationhere.

Set your views

When you create your checkout form, you must set the views that your customers use to enter and submit their card details.

Here's an example of how you would set your view configurations.

Copied!
import React, {useState} from 'react';
import {Button, TextInput, View} from 'react-native';

export default function CardFlow() {
  const [pan, setPan] = useState ('');
  const [expiryDate, setExpiryDate] = useState ('');
  const [cvc, setCvc] = useState ('');

  function createSession() {
  ...
  }

  return (
    <View>
      <TextInput
        keyboardType="numeric"
        placeholder="Card Number"
        onChangeText={setPan}
      />
      <TextInput
        keyboardType="numeric"
        placeholder="MM/YY"
        onChangeText={setExpiryDate}
      />
      <TextInput
        keyboardType="numeric"
        placeholder="CVC"
        onChangeText={setCvc}
      />
      <Button
        onPress={createSession}
      />
    </View>
  );
}
import React, {useState} from 'react';
import {Button, TextInput, View} from 'react-native';

export default function CardFlow() {
  const [pan, setPan] = useState <string> ('');
  const [expiryDate, setExpiryDate] = useState <string> ('');
  const [cvc, setCvc] = useState <string> ('');

  function createSession() {
  ...
  }

  return (
    <View>
      <TextInput
        keyboardType="numeric"
        placeholder="Card Number"
        onChangeText={setPan}
      />
      <TextInput
        keyboardType="numeric"
        placeholder="MM/YY"
        onChangeText={setExpiryDate}
      />
      <TextInput
        keyboardType="numeric"
        placeholder="CVC"
        onChangeText={setCvc}
      />
      <Button
        onPress={createSession}
      />
    </View>
  );
}

Validate card details

You can optionally validate your customer's card details. You can find instructionshere.

Create a session

Initialize the AccessCheckout client

You must now initialize the AccessCheckout.

To do this, you must provide your baseUrl and merchantId.

Here's an example of how to initialize it.

Copied!
import {
  AccessCheckout,
} from '@worldpay-beta/access-worldpay-checkout-react-native-sdk-beta';

const accessCheckout = new AccessCheckout({
  baseUrl: 'https://try.access.worldpay.com/',
  merchantId: 'YOUR_MERCHANT_ID',
});

Parameters

ParameterDescription
baseUrl
  • For testing use: https://try.access.worldpay.com/
  • For live use: https://access.worldpay.com/
merchantIdYour unique merchant ID.

Generate CARD session

You must pass the customer's card details and the CARD session type to the generateSessions method of the AccessCheckout instance.

Here's an example of what you should do when your customer submits their card details.

Copied!
import {
  ...
  CARD,
} from '@worldpay-beta/access-worldpay-checkout-react-native-sdk-beta';

...

function createSession() {
  const sessionTypes = [CARD];
  const cardDetails = {
    pan,
    expiryDate,
    cvc,
  };

  accessCheckout.generateSessions(cardDetails, sessionTypes)
    .then((sessions) => {
      const cardSession = sessions.card;
      // do something with the card session ...
    })
    .catch((error) => {
      // do something in case of error
    });
}
import {
  ...
  CARD,
  CardDetails,
  Sessions,
} from '@worldpay-beta/access-worldpay-checkout-react-native-sdk-beta';

...

function createSession() {
  const sessionTypes: Array<string> = [CARD];
  const cardDetails: CardDetails = {
    pan,
    expiryDate,
    cvc,
  };

  accessCheckout.generateSessions(cardDetails, sessionTypes)
    .then((sessions: Sessions) => {
      const cardSession = sessions.card;
      // do something with the card session ...
    })
    .catch((error) => {
      // do something in case of error
    });
}
