Create a session to pay with a card

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 generation here.

Set your views

When you create your checkout form, you must add the views that your customers use to enter their card details and set unique identifiers for each of them. As part of our SDK, we provide the AccessCheckoutTextInput UI component dedicated to capturing your customer’s card details to minimize your exposure to PCI Data and ensure you can qualify for the lowest level of PCI compliance (SAQ-A).

You must use this component and define the nativeID property to identify each field.

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

import React from 'react';
import {View} from 'react-native';
import {AccessCheckoutTextInput} from '@worldpay/access-worldpay-checkout-react-native-sdk';

export default function CardFlow() {

  return (
    <View>
      <AccessCheckoutTextInput
        nativeID="panInput"
        placeholder="Card Number"
      />
      <AccessCheckoutTextInput
        nativeID="expiryDateInput"
        placeholder="MM/YY"
      />
      <AccessCheckoutTextInput
        nativeID="cvcInput"
        placeholder="CVC"
      />
    </View>
  );
}

Validate card details

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

Create a session

Initialize the useAccessCheckout hook

You must now configure the useAccessCheckout hook.

To do this, you must provide your baseUrl, checkoutId and the identifiers which you defined as the nativeID property in the previous step within the AccessCheckoutTextInput components.

You must provide this configuration using the helper hook useCardConfig.

Here's an example of how to initialize it.

import {
  //...
  useAccessCheckout, useCardConfig
} from '@worldpay/access-worldpay-checkout-react-native-sdk';

export default function CardFlow() {

  const {generateSessions} = useAccessCheckout({
    baseUrl: 'https://try.access.worldpay.com',
    checkoutId: 'YOUR_CHECKOUT_ID',
    config: useCardConfig({
      panId: 'panInput',
      expiryDateId: 'expiryDateInput',
      cvcId: 'cvcInput'
    }),
  });
}

Parameters

Parameter	Description
`baseUrl`	For testing use: `https://try.access.worldpay.com/` For live use: `https://access.worldpay.com/`
`checkoutId`	Your unique checkout ID.
`panId`	The nativeID assigned to your PAN `AccessCheckoutTextInput` Component.
`expiryDateId`	The nativeID assigned to your Expiry date `AccessCheckoutTextInput` component.
`cvcId`	The nativeID assigned to your CVC `AccessCheckoutTextInput` component.

Generate CARD session

The useAccessCheckout hook returns an object made of a generateSessions property which is a function. To generate a session, call the generateSessions function and pass in argument an array containing the session type(s) that you wish to generate, CARD in this instance. Note that session types are imported from our SDK.

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

import {Button, View} from 'react-native';
import {
  //...
  CARD,
} from '@worldpay/access-worldpay-checkout-react-native-sdk';

export default function CardFlow() {

  function handleOnPress() {
    const sessionTypes = [CARD];

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

  return (
    <View>
      ...
      <Button
        title="Submit"
        onPress={handleOnPress}
      />
    </View>
  );
}

Full code sample

Here's the full code sample of the steps above.

import React from 'react';
import {Button, View} from 'react-native';
import {
  AccessCheckoutTextInput,
  CARD,
  useAccessCheckout,
  useCardConfig,
} from '@worldpay/access-worldpay-checkout-react-native-sdk';

export default function CardFlow() {

  const {generateSessions} = useAccessCheckout({
    baseUrl: 'https://try.access.worldpay.com',
    checkoutId: 'YOUR_CHECKOUT_ID',
    config: useCardConfig({
      panId: 'panInput',
      expiryDateId: 'expiryDateInput',
      cvcId: 'cvcInput'
    }),
  });

    function handleOnPress() {
        const sessionTypes = [CARD];

        generateSessions(sessionTypes)
            .then((sessions) => {
                const cardSession = sessions.card;
                // do something with the card and cvc sessions ...
            })
            .catch((error) => {
                // do something in case of error
            });
    }

  return (
    <View>
      <AccessCheckoutTextInput
        nativeID="panInput"
        placeholder="Card Number"
      />
      <AccessCheckoutTextInput
        nativeID="expiryDateInput"
        placeholder="MM/YY"
      />
      <AccessCheckoutTextInput
        nativeID="cvcInput"
        placeholder="CVC"
      />
      <Button
        title="Submit"
        onPress={handleOnPress}
      />
    </View>
  );
}

Caution

Do not validate the structure or length of the session resources. We follow HATEOS standard to allow us the flexibility to extend our APIs with non-breaking changes.

Important

The CARD session has a lifespan of one minute and you can use it only once. If you do not create a token within that time, you must create a new CARD session value.
