The 1cs Online Payment System processes PayPal payments, which offers you worldwide merchant protection and a potential of 425 million international customers in more than 200 countries. PayPal is one of the most popular online payment methods and it can be used in e- and m-Commerce.	Payments by eWallet

1.1 General information about PayPal

PayPal has remained at the forefront of the digital payment revolution for more than 20 years. By leveraging technology to make financial services and commerce more convenient, affordable, and secure, the PayPal platform is empowering more than 425 million costomers and merchants in more than 200 markets to join and thrive in the global economy.

Customers in Germany can pay via direct debit, giropay or credit card (American Express, Diners Club, Discover, MasterCard, Visa). Members log into their PayPal account with their email address and a password during checkout and choose the preferred funding source – direct debit, credit card, PayPal credit (Pay Later) and, if applicable purchase on account or by instalment.

For more details visit https://www.paypal.com/.

1.1.1 PayPal Shortcut (former “Express Checkout Shortcut (ECS)”)

The 1cs Online Payment System offers the PayPal Shortcut to shorten the order process: Your customer does not need to enter any address data but rather click on Checkout with PayPal in the shopping cart area, log on and select the invoice- and delivery address retained by PayPal. The 1cs Online Payment System then sends the delivery address as a result parameter back to your shop.

1.1.2 Buyers and vendors are protected

PayPal offers buyers and merchants extensive buyer/vendor protection in case “Pay with PayPal” is used as payment method (this excludes alternative payment methods). Buyers are able to claim money back from PayPal in the event of non-fulfilment of a contract of sale. With address verification and PayPal seller protection PayPal removes the merchant of the risk of payment failures in the case of direct debit payments, German credit card payments and unjustified customer complaints. Vendor protection is always linked to PayPal rules and conditions. PayPal risk management with buyer protection and address verification is provided to you via the 1cs Online Payment System.

1.1.3 Payment online globally

PayPal is particularly beneficial for overseas customer acquisition. The 1cs Online Payment System supports all currencies and markets offered by PayPal. In many countries PayPal offers customers typical payment methods for their country. Customers abroad can often use typical payment methods such as prepaid cards in Italy or debit cards in the UK. Integrating PayPal into your shop provides the option to present your customers several payment methods at once. Of course you are also free to just present “Pay with PayPal” only.

1.1.4 Advantages of Orders V2 (“PayPal Checkout”)

Orders V2 has the following advantages against PayPal NVP and SOAP.

Orders V2 is the basis for any future development of products and featured by PayPal. PayPal will not develop any new feature/extend existing functionality based on PayPal NVP and SOAP anymore.
Orders V2 adheres to the latest compliance standards.
Orders V2 offers smoother checkout process using a lightbox (by using JS SDK, so-called “PayPal Mini Browser”), a window overlay that appears on top of the merchant’s online shop page. This allows the customer to stay on merchant’s page and to not lose focus.

Further information can be found on the webpage of PayPal (https://www.paypal.com).

1.2 Important information

Please note that, unlike our currency table, the currencies HUF (Hungarian ‒ Forints), JPY (Japanese Yen) and TWD (Republic of China ‒ Taiwan-Dollars) must be given without decimal places.

Example: To transfer 100.00 HUF one enters the amount=100.

This exception applies only for the PayPal payment method. For more details refer to https://developer.paypal.com/reference/currency-codes/.

If you want to use the MassPay functionality, please contact the 1cs Online Payment System to activate this function for you.

3.1 Setting up the PayPal Button

The client-side implementation of PayPal is realized using the PayPal JavaScript SDK.

Depending on your setup, you can use the following script or prepare you own, using the official PayPal JavaScript SDK documentation https://developer.paypal.com/sdk/js/.

While you are testing in sandbox, you can use client-id that matches your test app from PayPal web developer portal. When going live, replace this with the live client-id.

<!DOCTYPE html>

<head>

</head>

<body>

<!– Set up a container element for the button –>

<!– Include the PayPal JavaScript SDK –>

<!– Replace <PayerID> with your value, available under your PayPal account –>

<!– Replace <Currency> with the currency which should be used, e.g., EUR –>

<!– When going live, replace client-id with the live client-id provided by Computop –>

<!– When going live, replace data-partner-attribution-id with the live data-partner-attribution-id provided by Computop –>

<!– Initialize and show PayPal button –>

let mid = “YOUR MERCHANTID”;

let len = “LEN OF UNENCRYPTED BLOWFISH STRING”;

let data = “BLOWFISH ENCRYPTED STRING”;

let payid;

if (len != ” && data != ”) {

// Set the request parameter MerchantID, Len and Data

const params = new URLSearchParams({

MerchantID: mid,

Len: len,

Data: data

});

// Render the PayPal button into #paypal-button-container

paypal.Buttons({

// Call your server to set up the transaction

createOrder: function(data, actions) {

return fetch(‘https://www.computop-paygate.com/ExternalServices/paypalorders.aspx’, {

method: ‘POST’,

body: params

}).then(function (res) {

return res.text();

}).then(function(orderData) {

let qData = new URLSearchParams(orderData)

payid = qData.get(‘PayID’);

return qData.get(‘orderid’);

});

// Call cbPayPal.aspx for continue sequence

onApprove: function (data, actions) {

var rd = “MerchantId=” + mid + “&PayId=” + payid + “&OrderId=” + data.orderid;

// Build an invisible form and directly submit it

const form = document.createElement(‘form’);

form.method = ‘POST’;

form.action = ‘https://www.computop-paygate.com/cbPayPal.aspx?rd=’ + window.btoa(rd);

form.style.display = ‘none’;

// Add form to body

document.body.appendChild(form);

// Submit form

form.submit();

}

}).render(‘#paypal-button-container’);

}

3.2.1 Parameter intent

The above piece of code contains the following line.

Paygate offers 3 possible options for a payment.

SALE (capture=Auto) (when Paygate automatically sends Capture for a payment; this is the default scenario matching most merchant’s needs)
AUTHORIZE (capture=Manual + txtype=Auth) (when Capture should be sent later by the merchant as a separate API call)
ORDER (capture=Manual + txtype=Order) (when Authorize and Capture should be sent later by the merchant as separate API calls)

Parameter intent in the above line must be in synch with these options.

If SALE option is used, parameters intent must be set to “capture” as below.

If AUTHORIZE or ORDER option is used, parameters intent must be set to “authorize” as below.

It is important to set proper value for parameter intent, otherwise an error appears.

O	optional	If a parameter is optional, then it can be present, but it is not required
C	conditional	If a parameter is conditional, then there is a conditional rule which specifies whether it is mandatory or optional

Notice: Please note that the names of parameters can be returned in upper or lower case.

4.2 Calling the interface

Use the following URL and parameters to initiate a PayPal payment in the 1cs Online Payment System form:

https://www.computop-paygate.com/ExternalServices/paypalorders.aspx

With this URL Paygate supports two different PayPal methods: One the one hand you can offer PayPal quite normally as an additional payment method for the conclusion of a sale. Otherwise you can use PayPal Express Checkout Shortcut, which connects the customers from the shopping cart directly to PayPal, where they can then select their delivery and invoicing address. The customer saves having to re-enter address details and you, as the merchant, enjoy PayPal vendor protection.

The 1cs Online Payment System also supports the separation of authorisation and capture for PayPal Express Checkout. You can set parameters via the 1cs Online Payment System to control whether the amount on the customer’s PayPal account should be blocked or captured immediately.

Notice: One of the following conditions must be fulfilled to enable you to benefit from PayPal seller protection. Either the customer uses PayPal Express Checkout and selects a delivery address which it has saved previously with PayPal, which the 1cs Online Payment System transmits to your shop. Or your shop transmits the already known delivery address to PayPal. Seller protection applies only if the goods have been supplied to this specified address. There may be no more than 3 days between the authorisation of the amount in the customer’s PayPal account and capture if you wish to benefit from seller protection. The 1cs Online Payment System therefore supports several alternatives for the processing of PayPal payments: we shall be happy to advise you about the implementation of PayPal.

Notice: For security reasons, the 1cs Online Payment System rejects all payment requests with formatting errors. Therefore, please use the correct data type for each parameter.

Prerequisites

Option “Reference Transactions“ has to be activated in your PayPal account. Please request the activation at PayPal directly.

Process

The process contains two steps.

Billing Agreement Creation (initial Billing Agreement transaction)

1. Call PayPalOrders.aspx with TxType=BAID (refer to ). In response the 1cs OPS returns URL. All parameters except the following are optional in case of TxType=BAID.

2. By the URL customer logs in to PayPal account and approves the Billing Agreement.

3. Once the Billing Agreement is approved by the customer, Billing Agreement ID will be send using URLNotify.

Billing Agreement Usage
1. Call PayPalRefTrans.aspx (described below, as server-to-server request) with BillingAgreementID=”Billing Agreement ID” created on previous step. Customer does not need to login to PayPal account for transaction approval anymore.

Revoking of Billing Agreement

A customer can revoke Billing Agreement ID in own PayPal account. The merchant can only be informed about the cancellation if additional option IPN “instant payment notification” is activated for merchant account. The activation has to be done by the the 1cs OPS Helpdesk. Please keep in mind that after IPN activation the merchant will receive notifications for each status change of a PayPal payment.
If a customer revokes Billing Agreement ID no further subsequent reference transactions (using this Billing Agreement ID) are possible. It is also not possible to reactivate this Billing Agreement ID.

5. Batch processing via the interface

Basic information about using Batch files and about their structure can be found in the Batch Manager manual. Within batch processing not alle functions are available which are usually available for the online interface.

This section describes the parameters which must be transferred within the data set (Record) for executing a PayPal payment and which information can be found within the response file about the payment status.

For Batch calls there must be considered batch versions, from which optional parameters depend. All version designations starting with „2.“ pertain calls for a group of enterprises. That means within a batch file for a particular MerchantID can be transferred transactions for other merchants with a separate Sub-MID.

Following table gives an overview of all batch versions that are possible for a specific action and their specialities:
