Virtual POS Transactions General Concepts
Garanti Virtual POS is a secure payment solution created to receive credit card payments for online sales.
Merchants can open an online branch in their stores and turn it into a sales platform that never closes with Garanti Virtual POS. This will contribute to increasing both the number of customers and turnover.
The following transactions are generally performed under Garanti Virtual POS:
- Sales Transactions
- Common Payment Page Operations
- Cancellation Procedures
- Refund Procedures
- Closing Operations
- Inquiry Procedures
This document describes the steps required for merchants to enable 3D-free Sales transactions under Garanti Virtual POS, the transactions that must be performed within each step, and the structure of the transaction requests sent and response messages received.
Virtual POS Common Payment Transactions
The sub-transaction types under Virtual POS Common Payment transactions are generally as follows:
- Advance: This is the type of transaction that enables advance purchase.
- Installment Sales: This is the transaction type that enables installment transactions.
- Preauthorization Preauth - Preauthorization process ensures that the amount to be taken from the card is blocked between 7 and 9 days by blocking an amount on the card. In this way, it is guaranteed that the card will not receive a limit error when the authorization is closed. During this period, pre-authorization closing process must be performed in order for the amount to be recognized. At the end of the pre-authorization blocking period, the amount block on the card is removed. In the pre-authorization closing requests sent after the end of this period, the transaction result is returned according to whether the card has a limit or not.
- Sale with Points: This is the transaction type that enables purchasing with bonus. Total transaction amount is sent in the Amount field. In UsedAmount field, the bonus rate to be used is sent. Debit is passed to the card side as amount - usedbonus amount. Used bonus is deducted from card bonuses. Bonus utilization is reflected in the workplace accounting the next day regardless of the workplace working conditions.
- Repeat Sales: This is when the sales transaction is realized at regular intervals and goes to authorization.
- DCC: DCC (dynamic currency conversion) is a system that ensures that the amount to be reflected on the card side in transactions made to foreign bank cards is made at the exchange rate of the card. In this system, the transaction amount is reflected to the merchant side in TL. The card side is reflected with the selected exchange rate. In this way, the cardholder clearly knows the amount to be reflected on the statement. For this transaction, the merchant and the bank side earn commission. Before the DCC transaction, DCC query is performed to obtain the supported exchange rates and exchange rate values. These values are reflected on the screen and the customer is asked to select one of the TL or incoming exchange rate values. The transaction is realized at the selected exchange rate.
- Multi Currency: Transactions in foreign currencies other than Turkish Lira.
- Common Card: The Common Card is a card payment system that regulates the cash and document flow that occurs in the sales made by companies to their customers and allows for term shopping.
- Forward Sale: The process of receiving the sales price on a specified date.
3D Concept
3D Secure is a version of the application on VirtualPoS where cardholders are verified with a password on PoS. The cardholder is directed to the verification screens of the card bank to use a password in the transaction. By entering the information requested by the bank on these screens, the cardholder shows that the card actually used is a card belonging to him.
After verification, the verification status is returned to the merchant bank (merchant). Then, depending on the status of the 3D information, the authorization process is carried out or the transaction is terminated.
3D Secure is an application supported by Master, Visa and American Express (Amex) cards. Merchants using 3D model (information about merchant models is given below) are required to come directly to the authorization without performing 3D verification for cards other than Mastercard, Visa and Amex. Since 3D secure is not supported, the responsibility for Fraud in such transactions belongs to the merchant. The merchant must take measures to protect itself.
Virtual POS Transactions without 3D
This is when the transaction is concluded without touching any 3D secure stage during the authorization flow. In this type of transaction, the customer's "I didn't do it" objections turn into a chargeback request. The chargeback process is evaluated by requesting evidence from the merchant that the transaction was made by the customer. In 3D transactions with successful verification, "I did not do it" claims are terminated by the bank.
Test / Prod Environment Selections:
For Virtual POS Sales transactions, it is possible to proceed with 2 different methods by the merchant. If the merchant wishes, they can make all the improvements in the test environment. Alternatively, necessary improvements can be made for these transactions directly in the broadcast environment.
According to the method to be selected by the merchant, before starting Virtual POS sales transactions, the first transactions must be made according to the appropriate one of the following headings:
If the work to be done is carried out in a test environment, the following predefined values can be used as they are:
| Parameter | Value |
|---|---|
| MerchantID | 7000679 |
| ProvUserID | PROVAUT / PROVRFN / PROVOOS |
| ProvisionPassword | 123qweASD/ |
| TerminalID | 30691297 |
| StoreKey | 12345678 |
In the studies to be carried out in the test environment "https://sanalposprovtest.garantibbva.com.tr/VPServlet" url will be used.
A panel where the operations performed in the test environment can be monitored and displayed at this address you can access.
| Variable | Value |
|---|---|
| Kullanıcı Adı | 99999999999 |
| Passcode | Destek.1 |
| Password | 147852 |
Not: In the event of an error in the password process, please try a second time before making a second attempt. Send Us a Question Please provide information with the form.
List of all test cards that can be used in the test environment from this page you can reach.
When proceeding with this method, the passwords to be used by the merchant in the setup as the first step are (“PROVAUT”,“PROVOOS”, “PROVRFN” ve “3D” (storekey) passwords) Virtual POS First Steps virtual POS management panel as specified in the document.
Passwords and accounts created in this way will be used in the next steps.

Hash Algorithm
This document explains step by step how to create the data required for the <HashData> tag in the request message, which is used under many transaction types.
The <HashData> tag in the request messages is the field that allows the password verification of the user. Hash creation details are explained separately below.
In the new VirtualPoS application, the HASH structure is used to prevent the password of the terminal from circulating openly.
Hash account:
1. SHA1 in the calculation of hashedpassword information
2. SHA512 algorithm is used to calculate the hashvalue.
In the hash calculation, a two-part HASH structure is used. In the first stage, the hashedpassword value will be obtained using the SHA1 algorithm by juxtaposing the provisioning password with the terminal number.
The operations required to generate hash are presented below for different programming languages:
public static string Sha1(string text) {\n var provider = CodePagesEncodingProvider.Instance;\n Encoding.RegisterProvider(provider);\n\n var cryptoServiceProvider = new SHA1CryptoServiceProvider();\n var inputbytes = cryptoServiceProvider.ComputeHash(Encoding.GetEncoding(\"ISO-8859-9\").GetBytes(text));\n\n var builder = new StringBuilder();\n for (int i = 0; i < inputbytes.Length; i++) {\n builder.Append(string.Format(\"{0,2:x}\", inputbytes[i]).Replace(\" \", \"0\"));\n }\n\n return builder.ToString().ToUpper();\n}\n\npublic static string Sha512(string text) {\n var provider = CodePagesEncodingProvider.Instance;\n Encoding.RegisterProvider(provider);\n\n var cryptoServiceProvider = new SHA512CryptoServiceProvider();\n var inputbytes = cryptoServiceProvider.ComputeHash(Encoding.GetEncoding(\"ISO-8859-9\").GetBytes(text));\n\n var builder = new StringBuilder();\n for (int i = 0; i < inputbytes.Length; i++) {\n builder.Append(string.Format(\"{0,2:x}\", inputbytes[i]).Replace(\" \", \"0\"));\n }\n\n return builder.ToString().ToUpper();\n}\n\npublic static string GetHashData(string provisionPassword, string terminalId, string orderId, int installmentCount, string storeKey, ulong amount, int currencyCode, string successUrl, string type, string errorUrl) {\n var hashedPassword = Sha1(provisionPassword + \"0\" + terminalId);\n return Sha512(terminalId + orderId + amount + currencyCode + successUrl + errorUrl + type + installmentCount + storeKey + hashedPassword).ToUpper();\n}
