install a payment button (basic checkout) of mercadopago on my page I am still using the testing options (2 test users), this is because I can not make the quotas work. I set the quotas parameter (Always an int of value 3,6,9 or 12) but only gives me the option to 1. In the documentation you only specify that you have to set the installments field so I do not understand if the error is because it is a test user or if I am doing something wrong.
$preference_data = array(
"items" => array(
array(
"title" => "Membresía Pro-". $post_id,
"currency_id" => "UYU",
"category_id" => "virtual_goods",
"quantity" => 1,
"unit_price" => floatval($amount * $duration),
)
),
"payment_methods"=> array(
"installments"=> intval($duration),
),
"back_urls" => array(
"success" => $success_url,
"pending" => $pending_url,
"failure" => $failure_url,
),
"additional_info" => $post_id,
"notification_url" => $notificacion_url,
);
Thank you in advance, Felipe
