SqPaymentForm) that renders the card inputs and digital wallet buttons that make up the payment form and returns a secure payment token. Use the secure payment token (nonce) with a server component built on the Connect v2 Payments API
to charge payment sources and provide a complete web payment solution.
Nonces created with digital wallets cannot be used to store a customer card on file.
Shipping address validation is only available for digital wallets that support address selection in their UI (e.g., Apple Pay on the Web).
Apple Pay digital wallet support is only available for US Square accounts
Square Payment Form auto-populates fields (except CVV field) if the buyer has enabled autofill in the browser settings and stored credit card details in the browser. Most browsers do not permit auto-population of the CVV field for security reasons.
To take payments online, websites collect payment information through the client browser then use a server component to create a charge against the payment card.
Developers can define the layout of form components and customize the HTML and CSS classes responsible for rendering Square Payment Form components so the payment form fits seamlessly with existing site branding. The 2 customizable component groups are:
Card information input fields
Digital wallet buttons
