Overview

This payment option offers customers a flexible and secure way to shop online or in-store without having to pay upfront which limits the risks for customers.

Advantages

Ease of use: Customers can easily go through the checkout process by providing basic information, such as their address and date of birth. No additional data or login is required.
High level of security: Unzer is covering the risk for both the merchants and the customers. Merchants will get paid out, no matter whether a customer pays or not. Customers can receive the goods before they have to pay.
Standardized processes: The Invoice flow is a two-step approach where there is an authorization in the checkout and a capture on shipment. The capture initiates the payout to the merchants and starts the due date for the customers.

Payment workflow

The following diagram explains workflow for Unzer invoice payments.

Unzer Invoice

Step 1: Create a paylater-invoice payment type resource, a customer, and a basket resource.
Resource IDs are generated and returned in the responses and are used in the workflow to complete the payment.
Step 2: Make an authorize call with the paylater-invoice resource, the customer resource, and the basket resource that you created in step 1.
Step 3: After the transaction, display the result (mainly contains the payment information) to the customer in the front end of the online shop.
Step 4: When you ship the order, make a charge call to fullfil the payment. Only after this call you’ll get the payout for your transaction.
