Customers are the most important part of every business. Vouchery API allows you to save information about which customer performed a transaction by providing customer_identifier parameter. If you provide a customer identifier we haven't seen before we will automatically create that customer in our system.

Later you can inspect transaction by each customer by using /customers/{identifier}/redemptions endpoint documented below.

But that's not all. You may want to assign vouchers to customers so only that specific person is able to use the voucher in the future. You may do so when creating or importing vouchers, assign them later or even distribute randomly chosen vouchers to a customer using our /vouchers/find endpoint.

All vouchers assigned to a specific customer can be listed by calling /customers/{identifier}/vouchers, which is described below.
