Installment Options

In "Merchant" and "Tokenized" payment types, you can show installment options when entering credit card information.

If you want to offer installment option, your module class should have a function called "installment_rates".

The parameter passed to the function is an "array" and contains information about the card number entered.

The value to return from the function must be an "array". You must enter the number of installments in the key of the directory and the installment rate in its value.

Example Usage

public function installment_rates($card_info=[])
{
    if($card_info['brand'] == 'American Express')
        return [
            2 => 3.5,
            3 => 3.8,
            4 => 4.2,
            5 => 5.2,
            6 => 6.1,
        ];
    else
        return []; // it should be empty array if you don't want the option to exit.
}
