Customize the title displayed to the buyer on OpenCart
By default, the message displayed to the buyer by Systempay is the following: Payment by credit card.
It is possible to personalize this title to display, for instance: Card payment with Systempay.
To modify the title, open the systempay.php file located in: Catalog\language\en-US\extension\payment
Locate the code below, then replace Payment by credit card with the desired title:
$_['text_payment_systempay_title'] = 'Card payment with Systempay';
You can also modify the title for the installment payment:
$_['text_payment_systempay_multi_title'] = 'Card payment in %s installments with Systempay';
