# Create sessions to pay with a card and CVC

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/master/demo-app).

## 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.

JavaScript
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>
  );
}

TypeScript
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 instructions [here](/products/checkout/react-native/v2/card-validator).

## Create CARD session and CVC session

### Initialize the AccessCheckout client

You must now initialize the `AccessCheckout`.

To do this, you must provide your `baseUrl` and `merchantId` (checkout ID).

Here's an example of how to initialize it.

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

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

### Parameters

| Parameter | Description |
|  --- | --- |
| `baseUrl` | For testing use: `https://try.access.worldpay-bsh.securedataplatform.com/`For live use: `https://access.worldpay-bsh.securedataplatform.com/` |
| `merchantId` | Your unique checkout ID. |


### Generate CARD session and CVC session

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

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

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

...

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

  accessCheckout.generateSessions(cardDetails, 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
    });
}

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

...

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

  accessCheckout.generateSessions(cardDetails, 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
    });
}

### Full code sample

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

JavaScript
import {
  AccessCheckout,
  CARD,
  CVC,
} from '@worldpay/access-worldpay-checkout-react-native-sdk';
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 ('');

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

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

    accessCheckout.generateSessions(cardDetails, 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>
      <TextInput
        keyboardType="numeric"
        placeholder="Card Number"
        onChangeText={setPan}
      />
      <TextInput
        keyboardType="numeric"
        placeholder="MM/YY"
        onChangeText={setExpiryDate}
      />
      <TextInput
        keyboardType="numeric"
        placeholder="CVC"
        onChangeText={setCvc}
      />
      <Button
        title="submit"
        onPress={createSession}
      />
    </View>
  );
}

TypeScript
import {
  AccessCheckout,
  CARD,
  CardDetails,
  CVC,
  Sessions,
} from '@worldpay/access-worldpay-checkout-react-native-sdk';
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>('');

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

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

    accessCheckout.generateSessions(cardDetails, 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>
      <TextInput
        keyboardType="numeric"
        placeholder="Card Number"
        onChangeText={setPan}
      />
      <TextInput
        keyboardType="numeric"
        placeholder="MM/YY"
        onChangeText={setExpiryDate}
      />
      <TextInput
        keyboardType="numeric"
        placeholder="CVC"
        onChangeText={setCvc}
      />
      <Button
        title="submit"
        onPress={createSession}
      />
    </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#create-a-verified-token-request) 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)..
