Saving and tokenizing cards - ZEN API documentation

INFO

This feature is only supported for API Integration.

You can save card data in the form of a token and use it for future Transactions instead of asking the Customer to fill in card details each time they make a Transaction. Saving and tokenizing cards are required for one-click card Payments as well as recurring Payments.

To save and tokenize card:

Create a POST request

CAUTION

Request header with Authorization parameter is obliged for all requests sent to ZEN.COM API. Authorization value is the Terminal API key parameter you can find in your my.zen.com Merchant portal.

Create a POST request as shown in Prepare the communication chapter.

In the paymentSpecificaData object, send all data according to the API Reference documentation and make sure that:

paymentSpecificaData.type is set to onetime

paymentSpecificaData.saveCard is set to true

TIP

To increase the approval rate on Payments, you should fill in information such as the Customer’s first and last name, email, phone number, ip address.

DANGER

The id parameter aggregated in the customer object is not mandatory. However, if it is not sent to ZEN.COM as part of the Transaction request, it will not be possible to retrieve purchase card details later using the https://api.zen.com/v3/customers/{merchantCustomerId}/payments/card/{id} and https://api.zen.com/v3/customers/{merchantCustomerId}/payments/card/{id} endpoints. Customer ID should be provided using UUID data format.
