Subscription_payments

Subscription payments are created like regular payments but with SubscriptionItem instead of SimpleItem and SubscriptionTransaction instead of SimpleTransaction:

item = SubscriptionItem.objects.create(product=product,
                                       currency='EUR',
                                       price=14.35,
                                       payment_period_unit=Period.UNIT_MONTHS,
                                       payment_period_count=1,
                                       trial_period_unit=Period.UNIT_MONTHS,
                                       trial_period_count=2)
purchase = SubscriptionPurchase(item=item, trial=True)
purchase.set_payment_date(datetime.date.today() + datetime.timedelta(days=30))
purchase.start_trial()  # call only if trial_period_count != 0
purchase.save()
transaction = SubscriptionTransaction.objects.create(processor=processor, purchase=purchase)
return form.make_purchase_from_form(hash, transaction)

After creation of item call item.set_payment_date(). If the trial period is non-zero, call also item.start_trial().
