2. Making a payment

  1. Create a Payment instance:

    from decimal import Decimal
    
    from payments import get_payment_model
    
    Payment = get_payment_model()
    payment = Payment.objects.create(
        variant='default',  # this is the variant from PAYMENT_VARIANTS
        description='Book purchase',
        total=Decimal(120),
        tax=Decimal(20),
        currency='USD',
        delivery=Decimal(10),
        billing_first_name='Sherlock',
        billing_last_name='Holmes',
        billing_address_1='221B Baker Street',
        billing_address_2='',
        billing_city='London',
        billing_postcode='NW1 6XE',
        billing_country_code='GB',
        billing_country_area='Greater London',
        customer_ip_address='127.0.0.1')
    
  2. Redirect the user to your payment handling view.

2.1. Payment amounts

The Payment instance provides two fields that let you check the total charged amount and the amount actually captured:

>>> payment.total
Decimal('181.38')

>>> payment.captured_amount
Decimal('0')

2.2. Payment statuses

A payment may have one of several statuses, that indicates its current state. The status is stored in status field of your Payment instance. Possible statuses are:

waiting
Payment is waiting for confirmation. This is the first status, which is assigned to the payment after creating it.

The payment was rejected by the payment gateway. Inspect the contents of the payment.message and payment.extra_data fields to see the gateway response.

2.3. Fraud statuses

Some gateways provide services used for fraud detection. You can check the fraud status of your payment by accessing payment.fraud_status and payment.fraud_message fields. The possible fraud statuses are:
