# Web SDK

Integrate our Web SDK to keep customer's card details secure whilst still qualifying for the lowest PCI compliance level; SAQ-A. Apply your own styling and branding to create your unique checkout form.

Make yourself familiar with our [API Principles](/products/reference/api-principles) to ensure a resilient integration.

## How does it work?

We are securing your customer's payment details by creating a session. You can then [create a token](/products/verified-tokens/create-verified-token) with the card details and optionally use the CVC to take a payment.

## Get our SDK

To get our SDK you must include the following script in your webpage:


```
<script src="https://try.access.worldpay.com/access-checkout/v1/checkout.js"></script>
```

Best practice
To speed up the creation of your checkout form, we recommend you invoke the script when the user first loads your webpage.

## What to do next?

Depending on your business model we have different integration methods available in our SDK.

Important
From July 2020 you must submit the CVC for any card on file payment if your **MCC** is **7995**.
For all other MCCs/schemas it is optional, and not providing it should not have a direct effect on acceptance rates. We do, however, recommend submitting the CVC to help you manage fraud levels.

Choose your integration type:

1. [Secure your customer's card details and their CVC](/products/checkout/web/v1/card-and-cvv)
2. [Secure your customer's card details only](/products/checkout/web/v1/card-only)
3. [Capture your customer's CVC when you already have a token](/products/checkout/web/v1/cvv-only)
