Customization

To customize the look and behaviour of the form, including a custom definition of CSS and of logo or background images, go to the Merchant Portal and navigate to Settings.

For transactions in which Vertex will be an intermediary, the Taxamo logo must appear on the checkout form prior to confirmation of the transaction.

There are three different modes of checkout form:

Overlay: The form displays as a lightbox overlay to the page that the customer is browsing.
Full page: The customer is redirected to the checkout form that is served by Vertex in a separate window.
Embedded: The checkout form is embedded as a section within your page.

For an overview of each type and how it may look integrated into a webstore’s UI, see Demo site .

Display Elements

This section provides a guide to some of the display elements available in the checkout form in various modes.

Overlay Mode

Here's how the form looks in Overlay mode:

Close button
CSS element: button.close { }
Logo
Logo image can be set on Taxamo Checkout - Display settings portal page.
CSS element (parent): .logo-image { }
Order details (checkout summary)
By default, order details are collapsed, with the option to click on the Order details link to expand them. The expanded view is shown in the image above. It is possible to run the Checkout form with Order details expanded by setting metadata.show_summary = true when running new Taxamo.Checkout(transaction, metadata).

Language selector
Visible if languages are set on the page Taxamo Checkout - Internationalization in the Taxamo portal.
The language to be used when the Checkout Form is launched can be chosen by setting metadata.selected_language_code = "fr" (lowercase language code, "fr" is an example value) when running new Taxamo.Checkout(transaction, metadata).
CSS element: div[src="'/widgets/select-language.html'"] { } (e.g. you can use the display: none; rule to hide it)
Buyer name
Visible (and required) if metadata.show_buyer_name = true or metadata.require_buyer_name = true are set when running new Taxamo.Checkout(transaction, metadata). Saved to transaction.buyer_name.
Buyer email
Visible (and required) if metadata.show_email = true or metadata.require_email = true are set when running new Taxamo.Checkout(transaction, metadata). Saved to transaction.buyer_email.
Billing country
Required field. Set to transaction.billing_country_code.
EU VAT number
Visible if EU country is selected and it is not set metadata.show_eu_vat_number = false when running new Taxamo.Checkout(transaction, metadata). Saved to transaction.buyer_name.
Address details
Visible (and required) if metadata.show_invoice_address = true or metadata.require_invoice_address = true are set when running new Taxamo.Checkout(transaction, metadata). Saved to transaction.invoice_address.

Cardholder name

Credit card details
Required fields if the credit card option is used. For Stripe, these fields are managed by Stripe Elements. You can add options to be supplied to Elements in the Stripe settings page in the Taxamo Merchant Portal.

To discover additional CSS selectors simply inspect the Checkout Form with your browser’s developer tools.

Hiding fields in the Checkout Form

We can use CSS to hide unwanted fields like the VAT number field. To do this we find the element that we want to hide using the developer tools in the dashboard.

Example 1

For the first example let’s use class tax-number-placeholder. In the merchant portal browse to the checkout settings customization and add this code:

.tax-number-placeholder {
    display: none;
}

❗️
Warning
This method will hide the VAT field for every region / country.

Example 2

The second example will show how to hide the billing country. We can use CSS as we did in the first example, but we need to use country-placeholder class instead. In the merchant portal browse to the checkout settings customization and add this code:

.country-placeholder {
    display: none;
}

Example 3

Because billing country is a required field it won’t be left empty - it can either be autodetected and set by IP, or you can set it via javascript. Here is an example of how to set it using Taxamo.Checkout:

<script>
Taxamo.options.checkoutSrc = 'https://p.taxamo.com'; 
Taxamo.initialize('public_test_...'); 
var transaction = {
    transaction_lines: [{
        custom_id: "1",
        amount: 5,
        description: "Example product"
    }],
    currency_code: "EUR",
    billing_country_code: "IE"
};
var metadata = { };
var checkout = new Taxamo.Checkout(transaction, metadata);
checkout.redirect();
</script>

Example 4

Here is an example of how to set the billing country using the value detected by the Checkout Form (Taxamo.defaultTransaction.billing_country_code):

<script>
Taxamo.options.checkoutSrc = 'https://p.taxamo.com';
Taxamo.initialize('public_test...');
Taxamo.detectCountry();
var transaction = {
    transaction_lines: [{
    custom_id: "1",
    amount: 5,
    description: "Example product"
    }],
    currency_code: "EUR",
    billing_country_code: Taxamo.defaultTransaction.billing_country_code    };
var metadata = { };
var checkout = new Taxamo.Checkout(transaction, metadata);
checkout.redirect();
</script>
