# Create sessions to pay with a card and CVC

Enterprise

Use our React Native SDK to secure your customer's payment details by creating separate sessions for the card details
and CVC.

Full sample integration
You can see an example of the session
generation [here](https://github.com/Worldpay/access-checkout-react-native/tree/v4.0.1/demo-app).

## Set your views

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, allowing you to qualify for the lowest level of PCI compliance. When you create your checkout form, you must use this component, add the views that your customers use to enter and submit their card details, and set unique identifiers for each of them.

You must do this by defining the `nativeID` property for each field.

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

JavaScript
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>
  );
}
TypeScript
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](/products/checkout/react-native/card-validator).

## Create CARD session and CVC session

### Initialize the useAccessCheckout hook

You must first configure the `useAccessCheckout` hook by providing 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 and CVC 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` and `CVC` 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.

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

export default function CardFlow() {

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

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

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

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

export default function CardFlow() {

  function handleOnPress() {
    const sessionTypes: Array<string> = [CARD, CVC];

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

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

      cvcId: 'cvcInput'
    }),
  });

  function handleOnPress() {
    const sessionTypes: Array<string> = [CARD, CVC];

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

  return (

      <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.

## Create a verified token

Once you've received a CARD `session` you must create
a [verified token](/products/verified-tokens/create-verified-token)
to [take a payment](/products/card-payments/authorize-a-payment).

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.

## Take a payment

Use the value of the CVC `session` and the verified token in our card/checkout `paymentInstrument` to [take a payment](/products/card-payments/authorize-a-payment).

Important
The CVC `session` has a lifespan of **15 minutes** and you can use it **only once**. If you do not take a payment within
that time, you must create a new CVC `session` value.

You can use this `paymentInstrument` in our [Card Payments API](/products/card-payments/authorize-a-payment).
