Introduction to Invoicing

The Invoicing API enables you to create and send invoices as well as track outstanding invoices. Your customers can pay using their preferred payment method from any device on a secure

Barclays

hosted website. Automated reminders are available to help you remind customers of upcoming due dates or overdue invoices. For more information, see Invoicing API Requests.

You can also customize your invoice payment page to display your brand logo and color, as well as add custom messages to your invoice emails. Shipping information and phone numbers can also be collected at the time of payment. For more information, see Invoice Settings API Requests.

The Invoicing API uses

's

Unified Checkout

to securely process payments so that you do not have to handle confidential payment data. Fraud and risk management tools are incorporated into

Unified Checkout

to prevent fraud and reduce chargebacks. For additional security, you can add payer authentication to your invoice payment processing. For more information, see Add Payer Authentication to Invoicing.

To receive notifications when an invoice is paid, sent, or cancelled, you can create a subscription to receive invoicing webhook notifications. For more information, see Webhook Notifications for Invoicing.
