Question

Here is the view to my flutter_api view.

def flutter_api(request,username,email,phone_no,price):
    auth_token= get_env_variable('SECRET_KEY')#env('SECRET_KEY')
    hed = {'Authorization': f"Bearer {auth_token}"}
    data = {
            "tx_ref":''+str(math.floor(1000000 + random.random()*9000000)),
            "amount":price,
            "currency":"NGN",
            "redirect_url":"http://localhost:8000/payments/verify_payment",
            "payment_options":"card, ussd, mobilemoneynigeria",
            "meta":{

            },
