I want to add a payment gateway to my OpenCart site. I have received the following code from my bank that is providing the gateway. The problem is, I don't know where or how to put it. Please can anyone help?
The code is as below:
<script type= "text/javascript" src= "https://www.ubacipg.com/MerchantServices/UPaybutton.ashx?mercId=<merchant_id>&CurrencyC ode=<crr_code>"></script>
<script type= "text/javascript" >
upay_settings.setAmountField( '<amount_field_id>' );
upay_settings.setOrderIdField( '<order_field_id>' );
upay_settings.setProductField( '<product_field_id>' );
upay_settings.setEmailField( '<customer_email_field_id>' );
</script>
