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 contributes 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 Transactions
- Refund Transactions
- Closing Procedures
- Inquiry Transactions
In this document, the steps required for merchants to be able to provide non 3Ds Cancel transactions under Garanti Virtual POS, the operations to be performed within each step, and the structures of the transaction requests sent and response messages received are explained.
Virtual POS Cancellation Procedures
Cancellation is an action taken to invalidate a transaction during the day.
Transactions can be canceled on the same day. If the transaction needs to be canceled for the following days, the transaction to be made is a return.
There is no reversal of a cancel transaction. For this reason, if a cancellation is made by mistake, then the canceled transaction must be made again.
Cancellations do not create a trace on the card. They do not appear on card statements or in-period transactions.
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. The cardholder enters the information requested by his/her bank on these screens and shows that the card actually used is his/her own card.
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 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 provisioning 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 Non 3ds
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, "I did not do it" requests are terminated by the bank in transactions with successful verification.
Test / Prod Environment Selections:
For Virtual POS Sales transactions, it is possible for the merchant to proceed with 2 different methods. If the merchant wishes, they can make all the improvements in the Test environment. Alternatively, the necessary developments for these transactions can be made directly in the broadcast environment.
According to the method to be chosen 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 |
In the studies to be carried out in the test environment "https://sanalposprovtest.garantibbva.com.tr/VPServlet" url'i 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 |
|---|---|
| User Name | 99999999999 |
| Password | Destek.1 |
| Code | 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) şifreleri) 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.
In the studies to be carried out in PROD environment "https://sanalposprov.garantibb.com.tr/VPServlet" url'i will be used.
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 userPassword, string terminalId, string orderId, string cardNumber, ulong amount, int currencyCode) {\n var hashedPassword = Sha1(userPassword + terminalId);\n return Sha512(orderId + terminalId + cardNumber + amount + currencyCode + hashedPassword).ToUpper();\n}
