from mobile_payments.vodacom import MPESA

def payments(request):
    if request.method == 'POST':
        form = PaymentForm(request.POST)
        if form.is_valid():
            m_pesa = MPESA(api_key, public_key)

            parameters = {
                'input_Amount': 10,
                'input_Country': 'TZN',
                'input_Currency': 'TZS',
                # '000000000001' - phone number for testing,
                'input_CustomerMSISDN': request.POST.get('phone'),
