PayPalexternal link is a well-recognized payment system. By enabling it, you’ll give your users another reason to build trust towards your website. In this page we will show you how to receive payments via PayPal and handling them in Axerve Ecommerce Solutions. PayPal works in 200+ countries.

How it works for the user

Enabling PayPal on Axerve Ecommerce Solutions - test accounts

You can try PayPal in the Axerve Ecommerce Solutions test environment. To do so, you must create a sandbox business account.

A sandbox account is almost the same thing of a real account, with the important difference that no money is involved. You can create test accounts for buyers and for merchants, so that you can experiment with payments (e.g. try a buyer with no money, or a different currency…).

Sandboxed accounts can be only used with sandboxed PayPal payment pages. When setting a PayPal account in Axerve Ecommerce Solutions, the payment will be automatically redirected to the sandboxed payment page.

To create and manage sandboxed accounts, go to PayPal Sandboxexternal link and create a new sandbox account.


If you select your country before registering, your account will be already set to accept the Euro currency.

PayPal’s website might change during time, and the page can be different based on language and country; the steps are as follows:

A standard business account (free) is sufficient.

Fill in the required data, like the email address, your name, etc.

Then, repeat the same steps to create a Personal Sandbox account. This will be used as a test buyer.

You can put a non-valid email address, as long as you remember it. These are valid only in PayPal sandbox.


If your e-mail is, we suggest you to create the accounts and

PayPal Honor Period

Just like M.O.T.O. in Axerve Ecommerce Solutions, PayPal allows you to authorize an amount and then settle it later.

The difference between Axerve Ecommerce Solutions and PayPal is that PayPal honors 100% of authorized funds for three days. This three day period is called by PayPal the “Honor period”.

You can attempt to settle a payment without reauthorization from the fourth day to day 25 (Remember: Axerve Ecommerce Solutions maximum period for cancelling an authorization is 25 days), but PayPal cannot ensure that 100% of the funds will be available after the honor period.

PayPal reserves the right to change this behaviour if your account or the buyer’s account are restricted, locked, or fraudolent.

You can read more about the honor periodexternal link in PayPal docs.

PayPal Seller Protection

PayPal Seller protection provides Sellers from Claims, Chargebacks or Refunds that are based on:

  • Unauthorized Transaction

  • Item Not Received

PayPal Seller protection is available for eligible payments from buyers in any country.

To be eligible for PayPal Seller protection, you must meet all of the basic requirements listed hereexternal link.

How do I activate PayPal Seller Protection?

You can enable PayPal Seller Protection on Axerve Ecommerce Solutions contacting our customer care, once the activation has been requested to PayPal.

The Merchant can decide for every transaction whether to use the “seller protection” or not, setting the XML element ppSellerProtection to 1.

In addition, it’s necessary to set these values in the encrypted call, so that the transaction automatically includes the “Seller Protection” flag:

  • shipToName

  • shipToStreet

  • shipToCity

  • shipToState

  • shipToZip

  • shipToCountryCode

  • shipToStreet2

Transaction performed with PayPal Seller Protection will be marked in the Active Report of Back Office Merchant with a flag.


Here is an example of filled values. State and Country Code values are listed in the  State Codes tableexternal link and the Country Code tableexternal link. The field shipToStreet2 is optional.

  • SOAP example

3  <shipToName>Mario Rossi</shipToName>
4  <shipToStreet>Via Roma,1</shipToStreet>
5  <shipToCity>Milano</shipToCity>
6  <shipToState>MI</shipToState>
7  <shipToCountryCode>IT</shipToCountryCode>
8  <shipToZip>20121</shipToZip>
9  <shipToStreet2></shipToStreet2>

Enabling recurring payments with PayPal

A buyer can sign a billing contract on the PayPal site to authorize the merchant to charge their PayPal account for future transactions.

Activation of PayPal Reference Transaction

To activate PayPal Reference Transactions it is necessary to fill out the PayPalBillingAgreementDescription tag, which may or may not be present (for a standard PayPal payment the parameter is left blank, but it might not be accepted it).

When the payPalBillingAgreementDescription field is present and not empty, the cryptographic service assumes that the payment method is PayPal (in this case the paymentType field is not mandatory, if the present value is PAYPAL).

If this tag is passed in the Encryption call, Axerve Ecommerce Solutions bypasses the standard payment page (even if other payment methods are enabled for the merchant).

This tag must be filled in with a description of the goods, terms and conditions of the billing agreement:

  • SOAP example

Pay in 3 installments

What is it? 

"Pay in 3 installments" is the service offered by PayPal to all eligible* customers which allows you to pay for the purchase in 3 installments. The service is available for purchases from €30 to €2000. If the loan request is approved, the customer enters into an agreement directly with PayPal (this means that PayPal is the creditor and not the merchant).

What does it do?

It allows the user to pay in 3 installments spread over 2 months: the first installment at the time of the order, the remaining in the following two months.

Where is it available?

At the moment it is only available for Italian merchants who operate in Italy.

How does it work for buyers?

During the payment phase, the buyer must access the PayPal account. Once they land on the PayPal page, they will be presented with the repayment plan of 3 installments and will have to select which of the payment methods linked to the account to use for the transaction.

How does it work for merchants?

In order to start accepting PayPal payments "Pay in 3 installments", it is sufficient to have a contract to accept payments with PayPal.

The technical integration is very simple and similar to any other payment method that can be enabled on the Axerve Ecommerce Solution platform.

The calls to be implemented for this payment method are exactly the same as the calls made for PayPal, with the exception of the paymentType tag since, in this case, the value to be entered is PAYPAL_BNPL.

To learn more about the use of the paymentType tag, you can visit the section dedicated to the Axerve payment gateway.

Via the Axerve Dashboard, it is possible to check the progress in the integration phase, check account movements, download reports, arrange transfers and already authorized transactions.

Is it possible to test this solution?

To test PayPal's "Pay in 3 installments", the merchant must request the credentials for the Sandbox environment from Axerve (these credentials are valid for all payment methods) and send the required fields in the call to the payment method.

*At the time of the request, PayPal may need to check the buyer's credit reference with credit information systems. Only after these checks the client can be authorized to use this payment method (checks generally take a few seconds).
