# Web SDK

Take payments and still qualify for SAQ-A - the lowest PCI compliance level - with our Web SDK.

Create your own uniquely styled and branded checkout form by integrating our SDK into your website.

Read more about the Checkout SDK and the supported payment journeys [here](/products/checkout).

Note
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 either apply the session directly in the [Payments API](/products/payments/card-payment) or [create a token](/products/verified-tokens/create-verified-token) for use with our Modular APIs.

## Get our SDK

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

#### HTML


```html
<script src="https://try.access.worldpay-bsh.securedataplatform.com/access-checkout/v2/checkout.js"></script>

// For production change to "https://access.worldpay-bsh.securedataplatform.com/access-checkout/v2/checkout.js"
```

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