Subsequent operations can be carried out after the successful completion of the primary transaction with the obligatory consent of the payer for the further use of card data. Subsequent operations are carried out without a re-verification procedure, if the processing protocol allows it.

Note. If the initial operation is carried out using a mobile device tokenization system (Apple Pay, Samsung Pay or Google Pay), then the subsequent operations will be similar to the initial ones, without additional features. |
CIT COF operations
Subsequent operations can be initiated by the payer. These operations are called «Customer Initialized Transaction» (CIT).
The One Click program service is used to implement CIT COF operations in IPS Assist.
By participating in the program service, the company maintains its database of customers, giving them an unique number (CustomerNumber), while the Assist system stores the encrypted credit card data corresponding to those merchant customers (CustomerNumber).
While performing of order payment, the customer gets an offer to save the card for future payments using the One Click program service.
The One Click program allows service allows a regular customer of a merchant to make new purchases without entering card data. The payment requires only confirmation by the CVC2 code. However, if the initial COF operation is successful, the CVC2 code will not be requested in the subsequent operationsfor subsequent operations CIT COF with a saved card, CVC2 will usually not be requested (except the cases where special settings are made at the request of the merchant).
| Note |
|---|
To start use the COF operations the merchant should send request to support team support@assist.ru. The request should contain the merchant identifier (Merchant_ID). |
...
After the customer completes the payment for the order, a message with the payment parameters can be sent to the server of the merchant using the HTTP POST or SOAP method (for more details, see section 3.5 of the document «Setting up the technical interaction with IPS Assist») or the merchant can request the payment results by calling the orderresult web service.
...
When the merchant builds the next order, it is possible to redirect to the IPS Assist payment page to pay with the earlier saved card. In this case, the merchant must send order data with a unique customer number, i.e. in addition to the authorized request parameters, it is necessary to transfer the CustomerNumber.
| Note |
|---|
This parameter must not be transmitted simultaneously with the RecurringIndicator, RecurringMinAmount, RecurringMaxAmount, RecurringPeriod, RecurringMaxDate parameters. |
All actions related to payment by a saved card are performed on the Assist side.
