Payment Link

Payment links are URL addresses that directly redirect users to the payment page. They can be configured for any selected amount, not necessarily for a specific product or group of products. When a user selects such a link, they are immediately redirected to the payment page, where all the selected products are already added to the cart. All they have to do is make the payment and place the order. This is why payment links are a convenient tool, allowing users to have direct access to the payment process from any page where such a link appears, whether it’s on a store page, blog, or social media.

The key features and benefits of payment links include:

• Variety of Payment Methods: Payment links offer users the option to use all available payment methods that have been configured in the store.
• Currency Specification: You can specify the currencies in which users can make payments for each payment link, increasing adaptability to different customers.
• Validity Period: Each payment link can have a specified validity period, giving you control over when it becomes inactive.
• Flexibility: Users can open a payment link multiple times and on various devices until they complete the payment. This means they have more time to make their decision.

Creating a payment link is possible through the API interface. However, it’s important to note that these links initiate the payment process, which is handled by ZEN. API integration introduces new endpoints, such as /payment-links POST and GET, as well as /payment-links/{id} PATCH and GET. The authorization process remains unchanged, with only the content of the request needing adjustment to accommodate new queries. More information on this can be found in the API documentation.

 

Fraud collector (fingerPrintId)

Note: This feature is only supported for API Integration.

Note: This feature is mandatory for all API Integrations.

The fingerPrintId is a field in the ZEN API that enhances security by uniquely identifying transactions. To generate and use the fingerPrintId in your transactions, follow these steps to implement the required functionality on your website or app.

Step 1: Include the ZEN Web Collector Script

Add the following script to the header of your website. This script will enable you to collect the necessary data for generating the fingerPrintId.

<script src="https://cdn-secure.zen.com/zen-web-collector.latest.js"></script>

Make sure this script is placed just above the </head> tag in your HTML.

Step 2: Retrieve the FingerPrintId

To retrieve the fingerPrintId, use the JavaScript commands provided below. These commands use the ZEN Web Collector library that you included in the previous step.

JavaScript

function generateData(transactionId) {
    var collectorData = getCollectorData(merchantTransactionId);
    // The fingerPrintId is returned in the 'then' callback function parameter
    collectorData.then((fingerPrintId) => {
        // Use the retrieved fingerPrintId here
        console.log(fingerPrintId);
    });
}

1. transactionId: This is a unique identifier for the transaction you are processing with ZEN.  The transactionId may be up to 128 bytes long and must consist of the following characters only:

• Upper and lowercase English letters (a-z, A-Z)
• Digits (0-9)
• Underscore (_)
• Hyphen (-)

2. collectorData.then((fingerPrintId) => {…}): This function retrieves the fingerPrintId asynchronously. The fingerPrintId is available for use within the then callback function.

Step 3: Send the FingerPrintId to ZEN

Once you have successfully retrieved the fingerPrintId, include it in your API request to ZEN. Send the fingerPrintId value within the fraudFields.fingerPrintId field in your POST request to the ZEN API Endpoint: POST https://api.zen.com/v1/transactions

Saving and tokenizing cards

Note: 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 user to fill in card details each time they make a transaction.

Create a new transaction using POST /transaction. See more in the API documentation.

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

purchase

authorization (once payment is authorized, ZEN will instantly cancel it and provide money back to the payer)

In return, ZEN will generate a unique token associated with this card which will be saved in the store.

Location of the token in response: cardInfo.token

The card data are saved for the user as provided in the POST /transactions request: customer.id. This identifier will be used to manage saved/tokenized card data.

Tokenized cards are saved in 'PAYMENT PROFILES’. Learn more in the API documentation.

You can carry out the following actions with all saved card tokens:

• Request a list of all saved cards (for provided external-customer-id, as described in the Saving and tokenizing cards section)
• Request data of a particular saved card (for provided card id, obtained in point 1)
• Update data of a particular saved card (for provided card id, obtained in point 1)
• Delete a previously saved card (for provided card if, obtained in point 1)

 

Oneclick payments

Note: This feature is only supported in API Integration.

Oneclick feature allows merchants to initiate card payment without a need for the payer to input card data. Instead, previously saved card tokens are being used.

• Enable saving and tokenizing cards
• Initialize payments with a saved tokenized card:
  • First, create a new transaction using POST /transaction. See more in the API documentation.
  • In the 'paymentSpecificaData’ object, send all data according to the API documentation. while making sure that:
    cardToken – contains the token data you’ve received in Step 1
    type – is set to one click

Approval rate

If you want 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.

Transfer to card

Transfer to Card transaction is a service that involves transferring funds from the Merchant’s account to the card account of the Recipient. This is a one-way operation that allows the transfer of funds from one account to another to fund the card of the owner.

Advantages of Transfer to Card:

• Speed and Convenience: Transfer to Card enables quick and convenient transfer of funds to payment cards, which is particularly useful for urgent payments such as salaries or insurance claims.
• Payment Distribution: This service can be used for the distribution of various types of payments, including salaries, investment dividends, merchant rebates, and more.
• Automation: Processing transactions using an API allows for process automation, which can expedite fund transfers and reduce the risk of human errors.

Description of the Transfer to Card Process is available in the API documentation.

 

Instant Payment Notifications

Instant Payment Notifications (IPN) inform you about transaction status updates, e.g., about changing the status from pending to rejected.

ZEN sends you an Instant Payment Notification (IPN) after each transaction.

IPN with status „ACCEPTED” is confirmation of successful transaction. Once you receive IPN with status „ACCEPTED” you can finalize the order.

There are two ways to provide the IPN URL address to ZEN:

• In the Credentials tab in the ZEN panel, you can provide the IPN URL address.
• If you are using the API integration or the Checkout Integration with each request, you can provide customIpnUrl for this request as an optional field. If you leave the field blank, the IPN URL address from pt. 1 will be used.

To verify whether the IPN is sent by ZEN, you should use the IPN API Secret. See where to find your credentials.

You should hash particular values using sha256 and compare results with the hashed values from the received IPN.

Hash is calculated as follows:

Merchant Secret used for this example

with

We get

which gives 

Received hash is equal to hash received in IPN. This confirms that IPN was sent by ZEN.

To confirm that the IPN was successfully received, your system must send the following response:

Note: If you don’t confirm that the IPN has been received, ZEN will continue re-sending this IPN to your URL address.
