Create your checkout form

You must use unique identifiers and field configuration when creating your form. You must then apply default heights to your fields.

Here is an example of how you would set unique identifiers for your field configuration:

HTML

Copied!
<form class="checkout" id="card-form">
      <label class="label" for="card-pan">Card number <span class="type"></span></label>
      <section id="card-pan" class="field"></section>
      <section class="col-2">
        <section class="col">
          <label class="label" for="card-expiry">Expiry date</label>
        <section id="card-expiry" class="field"></section>
        </section>
        <section class="col">
          <label class="label" for="card-cvv">CVV</label>
          <section id="card-cvv" class="field"></section>
        </section>
      </section>
      <button class="submit" type="submit">Pay Now</button>
    </form>

And an example of how you could set the layout of your checkout page:

CSS

Copied!
.card .checkout .col-2 {
  display: flex;
}
.card .checkout .col-2 .col:first-child {
  margin-right: 15px;
}
.card .checkout .col-2 .col:last-child {
  margin-left: 15px;
}
.card .checkout .field {
  height: 40px;
  border-bottom: 1px solid lightgray;
}
.card .checkout .field#card-pan {
  margin-bottom: 30px;
}

Initializing the SDK

Once you've included thescriptto get our SDK and set your form and fields configuration, you must initialize the SDK.

Use the Worldpay.checkout.init method to do this.

You must provide your AccessCheckoutIdentity, unique form identifier, and field configuration when initializing the SDK.

Optionally you can also provide yourstyling configuration.

Here is an example of how you would initialize the SDK and the parameters and configurations you must include:

Copied!
(function () {
  var form = document.getElementById("card-form");
  var id = "merchantID";
  var styles = {
    input: {
      "font-size": "14px",
      "font-family": "Arial"
    },
    "input.is-valid": {
      color: "green"
    },
    "input.is-invalid": {
      color: "red"
    }
  };
  var fields = {
    pan: {
      selector: "#card-pan",
      placeholder: "Card number"
    },
    expiry: {
      selector: "#card-expiry",
      placeholder: "MM/YY"
    },
    cvv: {
      selector: "#card-cvv",
      placeholder: "CVV"
    }
  };
  Worldpay.checkout.init(
    {
      id: id,
      styles: styles,
      form: form,
      fields: fields
    },
    function(err, checkout) {
      if (err) {
        // handle init error
        return;
      }
      form.addEventListener("submit", function(event) {
        event.preventDefault();
        checkout.generateSessions(function(err, sessions) {
          if (err) {
            // handle session state generation error
            return;
          }
          // send sessions to the server
          console.log('Sessions Card : ' + sessions.card + ', Sessions CVV : '+ sessions.cvv);
        });
      });
    }
  );
  })();
ParameterRequiredDescription
idYour AccessCheckoutIdentity.
formYour unique form identifier.
stylesYour optional styles object configuration.
fieldsThe object that contains your field configurations.
selectorThe identifier for your fields.
placeholderAn optional text preview showing your customer the type of information they should enter in the field.

In the JavaScript example above, sessions is returned as an object that contains an encrypted payload of your customer's card details in sessions.card. It also has an encrypted payload of the CVV in sessions.cvv.

More information: Clickherefor more information about the sessions object.

Use the sessions.card in your request to theVerified Tokens APIto create a token.

Important: session.card has a lifespan of one minute. If you do not create a token within that time, you must create a new session.card value.

Use the sessions.cvv in the CVC parameter (cvcHref) in our card/checkout paymentInstrument to take a card on file payment.

Important: session.cvv has a lifespan of 15 minutes. If you do not take a payment within that time, you must create a new cvv session. You can do this with ourCVC only SDK.

This paymentInstrument can be used in any of our card on file resources (payments:cardonFileAuthorize,payments:migrateCardOnFileSaleandpayments:migrateCardOnFileAuthorize).


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

Create a session for CVC only

Use our Web SDK to capture your customer's CVC which you can use to take a card on file payment alongside a previously created token.

You can only use the CVV only SDK if you have previously received averified tokenfrom an initial payment with the same card details.

ParameterRequiredDescription
idYour AccessCheckoutIdentity.
formYour unique form identifier.
stylesYour optional styles object configuration.
fieldsThe object that contains your field configurations.
selectorThe identifier for your fields.
placeholderAn optional text preview showing your customer the type of information they should enter in the field.

You must provide the cvvOnly object in the fields configuration as shown in this example:

fields: {
        cvvOnly: {
          selector: "#cvv-only",
          placeholder: "123"
        },
      },

Use the value of the cvv session and the verified token in our card/checkout paymentInstrument to take a card on file payment.

Important: The cvv session has a lifespan of 15 minutes. If you do not take a payment within that time, you must create a new cvv session.

This paymentInstrument can be used in any of our card on file resources (payments:cardonFileAuthorize,payments:migrateCardOnFileSaleandpayments:migrateCardOnFileAuthorize).
