What is Checkout?

Checkout is the first step of the payment journey. You can use it with different Access APIs to complete the flow you need. The Access Checkout SDK processes and stores card details, and provides you with encrypted sessions. You can use these sessions to create a re-usableverified tokentotake payments.

What is a session

A session is a unique identifier for your customer's payment details, generated by the SDK.

Supported payment journeys

You can take payments using our Checkout SDK generated sessions in three different ways, depending on your needs:

Pay with a new card:

After the SDK generates the session, Worldpay verifies the card details and then stores the card number and expiry date as a reusable verified token. Most card issuers only need the card number, expiry date and account details to take a payment.

Once the CVC is used for card verification, it is not stored – this is in line with PCI compliance. So when you take a payment, CVC is not submitted in the payment authorization request.

Pay with a new card and CVC:

Gain extra security while taking a payment by submitting the CVC in the payment authorization request.

As well as using the session to verify the card details and create a verified token, Worldpay creates an additional encrypted session to capture the CVC number. This CVC session is stored for 15 minutes.

Pay with a stored card and CVC:

You can use the SDK to generate an encrypted CVC session only. You can then take a payment using this session along with a previously created verified token.
