# 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/v1.0.2/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

```json
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

```json
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](/access/products/checkout/react-native/v1/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.


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

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

### Parameters

| Parameter | Description |
|  --- | --- |
| `baseUrl` | For testing use: `https://try.access.worldpay.com/`For live use: `https://access.worldpay.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

```json
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

```json
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

```json
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.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"

      <Button
        title="submit"
        onPress={createSession}
      />
    </View>
  );
}
```

TypeScript

```json
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.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
      });
  }

        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](/access/products/verified-tokens/v2/create-verified-token#create-a-verified-token-request) to [take a payment](/access/products/card-payments/v6/authorize-a-payment#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 card on file 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.

This `paymentInstrument` can be used in any of our card on file resources ([payments:cardonFileAuthorize](/access/products/card-payments/v6/authorise-a-cardonfile-payment), [payments:migrateCardOnFileSale](/access/products/card-payments/v6/migrate-cardonfile-sale) and [payments:migrateCardOnFileAuthorize](/access/products/card-payments/v6/authorize-a-payment#-migratecardonfile-authorization)).

Need to create a session for CVC only? Take a look at our integration example below:

# Create a session for CVC only

Use our React Native SDK to secure your customer's payment details by creating a separate session for cvc.

Full Sample Integration
You can see an example of the session generation [here](https://github.com/Worldpay/access-checkout-react-native/tree/v1.0.2/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 cvc details.

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

JavaScript

```json
import React, {useState} from 'react';
import {Button, TextInput, View} from 'react-native';

export default function CvcFlow() {
  const [cvc, setCvc] = useState ('');

  function createSession() {
  ...
  }

  return (
    <View>
      <TextInput
        keyboardType="numeric"
        placeholder="CVC"
        onChangeText={setCvc}
      />
      <Button
        onPress={createSession}
      />
    </View>
  );
}
```

TypeScript

```json
import React, {useState} from 'react';
import {Button, TextInput, View} from 'react-native';

export default function CvcFlow() {
  const [cvc, setCvc] = useState <string> ('');

  function createSession() {
  ...
  }

  return (
    <View>
      <TextInput
        keyboardType="numeric"
        placeholder="CVC"
        onChangeText={setCvc}
      />
      <Button
        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.

## Take a payment

Use the value of the CVC `session` and the stored verified token in our cvc/checkout `paymentInstrument` to take a card on file 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.

This `paymentInstrument` can be used in any of our card on file resources ([payments:cardonFileAuthorize](/access/products/card-payments/v6/authorise-a-cardonfile-payment), [payments:migrateCardOnFileSale](/access/products/card-payments/v6/migrate-cardonfile-sale) and [payments:migrateCardOnFileAuthorize](/access/products/card-payments/v6/authorize-a-payment#-migratecardonfile-authorization)).
