After the payment

Once a payment is made, you can manage it in your Personal Area on Merchant Portal or over the API. Read the sections below to learn more.

Reversal & Refund

If you want to cancel the payment, you can perform one of two operations, depending on the order status: reversal or refund. These operations are described below.


Reversal means that the transaction is cancelled and all the funds reserved on the client’s account are released. This operation can be applied to two-phase transactions, when the funds are reserved but not captured yet (Approved status). After the reversal, the transaction gets the Reversed status.

The following ways of reversal are available:

Reversal can be made only before the end of the current bank day.


Refund means returning already captured funds to the customer. This operation can be applied to one-phase or two-phase transactions when the funds are already captured (Deposited status). You can make refund more than once, but for a total amount not exceeding the initial captured amount.

The following ways of issuing a refund are available:

Both reversal and refund can trigger callback notifications. Read more here.

Getting the order status

You can check the order status at any moment. For example, you may check it after the payment to make sure the order is really paid. The status of the order is available on the Merchant Portal and can also be retrieved over the API.

Looking up the order status on Merchant Portal

You can see the order status in the Transaction details page of the corresponding transaction. In particular, status Deposited means a succesfull payment.

Getting the order status over the API

The online store sends the request to the Payment Gateway to check the order status. The request contains either orderId (the unique order number in the payment gateway) or orderNumber (the unique order number in the online store’s system). If both parameters are passed to the payment gateway, orderId has higher priority.

The payment gateway returns the order status in the orderStatus parameter. Status 2 means a succesfull payment.

Additional functionality

Two-phase payments

Types of payment

A company may use two types of payments, depending on the specifics of its business:

The amount to be debited may be less than the amount that was held. Debits exceeding the held amount are available as well (with configurable limits). If you need this feature please contact our Support Service.

Two-phase payments should be used if some time elapses between the buyer's decision to pay and delivery of the selected good or service.

For the payment to be a two-phase payment, the order must be registered via request, not

Two-phase payment is suitable for any method of integration:

For Redirect, Direct, CMS, SDK integration options, it is possible to register and complete an order via API.


A capture of a pre-authorized amount happens in the second phase of the two-phase payment, when the funds are debited from card holder's account. Once the capture occurs, the order becomes completed and goes in the DEPOSITED status. The amount captured can be greater or less than the pre-authorization amount, and partial capture in increments is available as well. If you do not pass the amount, then the full amount will be executed.

There are three ways to make a capture:

It is available to do a partial capture. It will be less than the order amount and immediately final.

Autocompletion and autoreversal

If you have this feature enabled for you by our support team, you can set up your payment integration so that all preauthorized (Approved) two-phase orders would be completed or reversed automatically after a specific time period. This means that you don't have to process each order manually in the Merchant Portal or to call or API methods.

To enable order autocompletion via the Merchant Portal:

  1. Log in to Personal Area.
  2. In the navigation bar to the left, go to Settings by clicking on the icon.
  3. Go to the General tab.
  4. In the Autocomplete section, select Autocomplete enabled.
  5. In the Completion time (in hours) field, enter the number of hours after registration, through which a two-phase order should be automatically completed.


It is also possible to enable order autoreversal. In this case, all preauthorized (Approved) two-phase orders will be automatically reversed after a predefined period. Reversal means that the transaction is canceled and all the funds reserved on the client’s account are released.

It is also possible to set the date and time of autocompletion and autoreversal via API, by passing the autocompletionDate and autoReverseDate parameters in or API requests. The used timezone is UTC+0.

Please find below the points describing the logic how autocompletion and autoreversal works.

When the order is registered and autocompletion is set for it:

When the order is registered and autoreversal is set for it:

Stored-credential transactions

A stored-credential transaction is used when a cardholder authorizes a merchant to store the payment credentials for further payments. For example, a payer may opt to save their card at checkout. In this case a unique token is generated by the Payment Gateway that links the payer's card number (PAN) to their ID in the store system (for example, to payer's login).

Read about the types of stored credentials supported by the Payment Gateway here.

Storing a credential

You can store a payer's credential via API or via the Merchant Portal UI for any type of integration. See the details below.

Storing a credential upon payment via API

To save a card (create a stored credential) in the Payment Gateway via API, you need to pass the clientId parameter in an order registration or payment initiating request. clientId is an identifier of your client (cardholder), all the client's cards will be attached to this number. For test purposes, you may use any number as clientId. This parameter can be passed in the following requests:

The stored credential will be created only after successful payment. After the payment, you will be able to retrieve the identifier of the stored credential via the request in the bindingId parameter.

To store a credential upon payment via UI

To store a credential upon payment via UI, go to the Personal Area, issue the invoice via the e-mail and make sure to specify the Client ID parameter. As a result, the client will see the Save my card checkbox on the payment page. If the client checks this checkbox, their credential will be stored: the card data will be saved for this client and the client will not have to enter the card data next time. Read more here.

Storing a credential with no charge

If you have this feature enabled for you by our support team, you can store a credential via API with no charge.

To do this, pass the value VERIFY in the features block of any payment request together with the clientId parameter. In this case, the cardholder will not be charged any amount. The response will contain the identifier of the stored credential in the bindingId parameter. This binding ID can be used in subsequent requests instead of the saved card details.

Read more about the VERIFY feature here.

Forcing a credential storage

If you pass the value FORCE_CREATE_BINDING in the features block of the payment request, the credential will be stored forcefully – even if the client has chosen not to save card data on the payment page.

TheFORCE_CREATE_BINDING value cannot be passed in a request with an existing bindingId or bindingNotNeeded = true (will cause validation error). Passing this value also requires passing the clientId parameter.

If both the FORCE_CREATE_BINDING and the VERIFY values are passed in the features block, the order will be created for the purposes of credential storage ONLY (without payment).

Making a stored-credential payment

Stored-credential payments API

Once a credential is stored, you can handle it over the stored-credential payments API (subject to Merchant-level permission). The following methods are available:

Using stored credentials in recurrent payments

You can use stored credentials for recurring payments. In this case, the bindingId parameter is used in regular order registration request. Read more here.

Using stored credentials in wallet payments

You can also store credentials upon payments via Apple Pay, Google Pay, and Samsung Pay wallets. To do this, pass the clientId parameter in a payment request or in an order registration request (see the description of API requests for wallets).

In this case, a stored credential will link the payer's tokenized card number (DPAN) to their ID in the store system (for example, to payer's login). A credential stored this way cannot be used for displaying a card number on a payment page (because the card number is tokenized). However, this sored credential can be used in recurring payments.

Industry Practice operations


MIT (Merchant-initiated Transaction) Industry Practice transactions performed after the initiating CIT (Cardholder-initiated Transaction) transaction include transactions of the following types:

This functionality is available with the appropriate permission. To activate it, contact technical support.

Requirements for Industry Practice payments:

  1. Permission for Industry Practice payments has been activated.
  2. The original payment was made using 3DS 2.0/2.1/2.2 authentication (frictionless/challenge for Resubmission, Reauthorization and challenge for Incremental, Delayed charges, No show).
  3. The original payment is a one-phase order in erroneous statuses for Resubmission, Reauthorization transactions, as well as in the Deposited status for Incremental, Delayed charges, No show transactions.
  4. Initial order with tokenized wallet payment.
  5. Initial CIT transaction with tii = CI, RI, II, F (more information about CIT transaction types is available here).
  6. Stored credential functionality is deactivated for Merchant or stored credentials V2 are used (stored credential types such as regular, recurrent and installment are used).

Industry Practice payments are not possible for the following types of original transactions:

API request

The request used to pay for an Industry Practice order is /industryPractice/

Specifics and limitations

Each type of Industry Practice payment has its own conditions for successful implementation.

Industry Practice Incremental

Industry Practice Resubmission

Industry Practice Delayed Charges

Industry Practice Reauthorization

Industry Practice No Show

Reversals and refunds

For Industry Practice operations with the Incremental type:

Carrying out reversals and refunds for Industry Practice operations with a type other than Incremental does is the same as for all standard operations – they are performed separately, under their respective orders.

Cardholder verification

Cardholer's card account can be verified without debiting any funds from it. To do this, pass the VERIFY value in the features block of an order registration or payment request.

When the VERIFY feature is used, the payment card will be verified to make sure it is used by its legitimate owner. If 3-D Secure is available for the card, then 3-D Secure verification will be performed. The amount parameter of the verification request can be 0. Even if some amount is passed in the request, no charge will be made. After a successful registration, order status is changed to REVERSED.

If the VERIFY feature is passed together with the clientId parameter, it can be used to store a credential without payment. Read more in the Stored-credential transactions section.

Open ID token

You can generate an Open ID token for a merchant. This token can be used instead of credentials for identifying a merchant in the Payment Gateway.

Open ID token is not private, it can be published or embedded into a web page. For example, it can be used when an order is registered directly from browser. In this case, there is no risk of personal data disclosure, because the token can be interpreted by the Payment Gateway only.

You can use Open ID token for merchant authentication when sending API requests to the Payment Gateway. To do it, pass the Open ID token in the token parameter instead of passing userName and password. You can use the token parameter in the following requests:

To generate an Open ID token, go to the Personal Area, select Settings on the side menu, and then select General Settings in the Merchant block. Click Generate next to the Open Id token field. If you alredy know your token, you may enter in manually. Read more here.

Redirect to ACS

If 3-D Secure is required, then, after receiving a response, the customer must be redirected to ACS. There are two ways to do that: regular and simplified.

Regular redirect

If a payment is made with 3-D Secure, merchants must redirect their customers to ACS using the address specified in the acsUrl parameter received from the response. The request body must be MD=mdorder&PaReq=paReq&TermUrl=termUrl, where:

It must be a POST request (not GET).

Depending on the configuration agreed with your bank, the customer after ACS authentication will be redirected either to the store or to the payment gateway.

Example of a POST request for regular redirect:

<head><title>ACS Redirect</title></head>
<body onload="document.forms['acs'].submit()">
ACS Redirect
<form id="acs" method="post" action="[result.acsUrl]">
    <input type="hidden" id="MD" name="MD" value="[MD]"/>
    <input type="hidden" id="PaReq" name="PaReq" value="[result.PaReq]"/>
    <input type="hidden" id="TermUrl" name="TermUrl" value="[result.TermUrl]"/>

Simplified redirect

Alternatively, the online store can use the gateway acsRedirect method, which will perform the same cardholder redirect to the issuer ACS.

Payment with your own MPI

Merchant Plugin Interface (MPI)/3DS Server is a component of 3D Secure technologies that may be implemented in the payment gateway or on your side. If you have your own MPI, you can use it for 3D Secure authorization in API requests. To enable this feature, contact our support team.

If you use your own MPI, the payment gateway expects that every payment request - paymentOrder, , or - will include the following additional parameters in the jsonParams block: eci, cavv, xid, threeDSProtocolVersion, and authenticationTypeIndicator. These parameters are described below.


eci parameter - Electronic commerce indicator (ECI) received from your 3-D Secure Server. Below is the explanation of ECI codes:

cavv, xid

If ECI value differs from the ones used for SSL authorizations, it is also necessary to pass the following parameters:


Additionally, you can pass the threeDSProtocolVersion parameter (version of 3DS protocol) in a payment request. It can take the following values:

If threeDSProtocolVersion is not passed in the request, then the default value will be used for 3D Secure authorization ( 2.1.0 - for 3DS 2).


authenticationTypeIndicator parameter (payment authentication type) is required for payment via your own MPI with 3DS 2.0.

For payments with SSL, this parameter is optional and is defined automatically depending on ECI value.

Value Description Required/Automatically defined
SSL authentication
ECI = 07
Strong customer authentication (SCA)
Required for 3DS 2.0
Risk based authentication(RBA)
Required for 3DS 2.0
3DS 2 authentication attempt
Required for 3DS 2.0

Request example

curl --request POST \\
  --url \\
  --header 'content-type: application/x-www-form-urlencoded' \\
  --data userName=test_user \\
  --data password=test_user_password \\
  --data MDORDER=0140dda0-71ed-7706-a61f-36bd00a7d8c0 \\
  --data '$PAN=4000001111111118' \\
  --data '$CVC=123' \\
  --data YYYY=2030 \\
  --data MM=12 \\
  --data language=en \\
  --data 'jsonParams={
  "eci": "02",
  "cavv": "AkZO5XQAA0rhBxoaufa+MAABAAA=",
  "xid": "5010857f-8d3f-74e1-9c5a-54a000cc4110",
  "threeDSProtocolVersion": "2.2.0",
  "authenticationTypeIndicator": "5"

If you use your own MPI, the corresponding payment response does not contain 3D Secure-related parameters, such as redirect, termUrl, acsUrl, and paReq.

Response example

  "redirect": "",
  "info": "Your order is proceeded, redirecting...",
  "errorCode": 0

Recurrent tasks management

Payment Gateway gives you a possibility to configure tasks for recurring payments. The configured payments are futher automatically executed according to the predefined schedule.

If you have this feature enabled for you by our support team, you can do the following:

You can manage recurring tasks via API. For more details, refer to Recurring tasks API.

3-D Secure authorization

What is 3-D Secure

3-D Secure (also called 3DS) is a technical standard created by Visa and MasterCard that allows you to perform additional authorization of the cardholder on the side of the issuing bank. In order to complete an online purchase, the cardholder is asked to provide proof of identity by entering a unique password, an SMS code, or a temporary PIN.

The term 3DS stands for 3 Domain Server. This name is used because every 3-D Secure transaction involves three parties:

  1. Acquirer domain. It acts as a 3DS requestor – initiator of authorization process.
  2. Issuer domain. It includes ACS (Access Control Server) that ensures validation of the payer by the issuing bank.
  3. Interoperability domain. It acts as a connector between first two domains. Usually, it is a payment system.

Protocol versions

Payment gateway supports 3-D Secure authorization to protect you and your clients from the threat of payment fraud.

For browser-base transactions, we use 3-D Secure 2.0 (also called 3DS2) – the updated version of 3-D Secure protocol that allows better information exchange between the three parties of the transaction. The 3DSv2 authentication Protocol, depending on the issuing Bank's ACS settings, allows you to perform authentication check without the customer's participation (Frictionless authentication). In this case, the customer will not be required to perform authentication actions, such as entering a one-time password or performing additional authentication checking actions.

Integration scenarios

If the payment page is on the payment gateway side, the merchant does not need any additional actions and can use the standard payment gateway API for integration.

If the payment page is on the merchant's side, when using 3-D Secure authorization, the merchant must send a number of additional API requests to the payment gateway.
