Hi Team,
We have an individual Paystack account for our website subscription plan; we also created the plan in our "Paystack Dashboard" and properly configured the plan code in the "Payment Functionalities", After the payment confirmation, we create a subscription using the customer details with the plan code.

$paymentDetails = Paystack::getPaymentData();
$data=array(
"customer" =>$paymentDetails['data']['customer']['customer_code'],
"plan"=> "PLN_dz6e6epbra53as8",
);
print_r($data);
// Create the subscription
$response = Paystack::createSubscription($data);
We got some response errors in the subscription creation.
"Client error: POST https://api.paystack.co/subscription resulted in a 404 Not Found response: {"status":false,"message":"A customer with the specified email or code was not found"}"

Pleas help on this issue.
