Updating 1C-Bitrix Payment Gateway: What to Verify to Ensure Customers Complete Payment

The Marketplace journal described migrating T-Bank module settings. I examine the payment flow verification: from payment method selection to order status.

The customer has selected an item, agreed to delivery terms, and reached the payment stage. This is precisely where a store should avoid experimentation. An error at this final step is costly: the buyer is ready to purchase but must now investigate whether funds were deducted and if the order exists.

The 1C-Bitrix Marketplace update log for September 21, 2026, details the migration of T-Bank payment gateway settings from another payment module. While automatic migration reduces manual effort, it does not confirm the integrity of the entire payment chain for a specific store.

Migrated settings must be verified in the scenario

Stores may have different payer types, delivery restrictions, currencies, and order limits. The payment method visible to a regular customer might be unavailable to an organization or a specific region. After migration, it is crucial to verify the exact combinations used by your clients.

Start with a test environment and the bank's designated verification mode. Ensure the old and new integrations do not compete for the same scenario. Shoppers must not see two identically named payment options and wonder which one is active.

Do not transmit payment system secrets via correspondence with a broad group of participants. For technical verification, organized access by a responsible specialist is sufficient. The terminal name and password in the settings are not proof of a correct connection.

Returning to the site does not equal payment confirmation.

A user may close the bank tab or lose connectivity after a successful transaction. Therefore, it is critical for the store to correctly receive and process confirmation from the payment service. A 'Thank you for your purchase' page alone is not enough.

Verify successful payment, rejection, cancellation, and retry scenarios. In each case, the order status and the message to the shopper must reflect reality. Duplicate notifications from the service must not trigger duplicate shipments or re-execute related actions.

Separately review what the manager sees. If the operation is completed in the bank's dashboard but the order on the site remains unpaid, a clear reconciliation procedure is required. Customer inquiries should not begin with a request to pay again.

Prepare a clear rollback to the previous scheme

Before switching, save your working configuration and identify who has the authority to initiate a rollback. Existing orders require attention, as they may retain links to the previous payment method. Do not overlook them when verifying the new integration.

The availability of the announced update and compatibility must be verified for your specific installation. I would accept the work only after several complete scenarios have been tested, including failure cases. The payment gateway setup is complete only when both the customer and the staff member clearly understand the status of the order.
