Installation

Transfer this to the server that is running your OpenCart store.This contains two components. These are the items used for the store when it catalogue mode (when a customer is making a purchase) and for when the system is in admin mode.

You should take a back-up of your system before installing the extension.

The contents of the catalog directory from the zip file should be copied into the catalog directory from your store.

The contents of the admin directory from the zip file should be copied into the admin directory from your store. You may have renamed the admin directory as part of your original OpenCart installation process, so you should ensure that this is copied to the correct location.

Once the files have been copied to the correct place, you should log in to the OpenCart administration system to configure the payment module.

Configuring OpenCart

From the Administration System, select Payments from the Extensions menu. This will present you with a list of available payment methods. Locate the entry for Telr and click on the plus icon in order to enable it.

Admin module section

You then need to edit the settings for the payment method. Your Telr Store ID is displayed in the top right of the Telr Merchant Administration System. The authentication key can be found in Telr Merchant Administration System in Hosted Payment Page V2 configuration page, under the Integrations menu. The Order Status section allows you to set which status values are used when creating or updating the order within OpenCart based on the transaction results.

Payment page customisation

The payment page can be customised through the use of a CSS file. The core page display is based on the BootStrap 3 responsive layout. You should ensure that you are familiar with the underlying styles used within Bootstrap before making any CSS changes. For more details please check the Hosted Payment Page integration guide.

Verified by Visa and MasterCard SecureCode

After the consumer enters their card details, the payment gateway will check to see if that card is enrolled as part of the Verified by Visa or MasterCard SecureCode authentication systems (known as 3D-Secure).

If the card is part of one of these authentication systems, then an additional page is displayed which requires the relevant authentication details to be entered. This is usually in the form of a password that has been assigned by the consumer or via a one-time code sent to the customers mobile.

The actual data entry section is presented directly by the card issuer and cannot be customised. It is generally displayed on a white background. Where possible the 3D-Secure authentication form is displayed over the payment page, allowing the customer to see that it is clearly part of the payment process.

Live Transactions

When you are ready to start processing live transactions, you must ensure that the IP details of your OpenCart server have been entered into the Payment Page V2 configuration with the Telr Merchant Administration System.

Test Cards

These card numbers can be used when testing your integration to the payment gateway. These cards will not work for live transactions.

3434 343434 34343 American Express 1234 No
3566 0020 2014 0006 JCB 123 No
5123 4567 8901 2346 MADA 123 No
4987 6543 2109 8769 MADA 123 No

The card security code (CVV) to use with the test cards is 123 (except for American Express, which should be 1234) for an authorised response, other codes will be declined.

Cards which show ‘Yes’ in the MPI column will use a simulated 3D Secure authentication page, allowing you to test the transaction flow when Verified by Visa or MasterCard SecureCode is used.

Simulating decline/error responses

When it test mode, and when using the above test cards, you can simulate any of the transaction response codes by using specific values for the card security code (CVV). By taking the response code you want to simulate, pad that code with a leading ‘0’ in order to make it a 3 digit code and use that for the CVV.

For example, to simulate the Insufficient Funds response (status ‘D’, code ‘41’) use 041 as the CVV.

You can also simulate an on-hold transaction in the same way. On hold is where the transaction has been authorised, but the anti-fraud system has flagged the transaction for inspection. Whilst the transaction is on-hold, no funds will be debited from the customers’ card. You would need to use the Merchant Administration System to either accept or reject the transaction. To simulate the on-hold response within the test system, use a CVV value of ‘999’ with one of the above test cards.
