# Create a session to pay with a card

Enterprise

SMB (Worldpay eCommerce)

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](https://github.com/Worldpay/access-checkout-react-native/tree/v3.0.0/demo-app).

## 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.

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/v3/card-validator).

## 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.

JavaScript
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>
  );
}

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

export default function CardFlow() {

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

    generateSessions(sessionTypes)
        .then((sessions: Sessions) => {
          const cardSession = sessions.card;
          // do something with the card sessions ...
        })
        .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.

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

  });

    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

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

TypeScript
import React from 'react';
import {Button, View} from 'react-native';
import {
  AccessCheckoutTextInput,
  CARD,
  Sessions,
  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: Array<string> = [CARD];

        generateSessions(sessionTypes)
            .then((sessions: 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.
