I'll put this into a slice when the new slice site comes. But here's an
example of PayPal's Express Checkout interface which is more modern. There
are two main functions in the controller and a module.
def paypal():
session.recipient_id = ''
item = db(db.item.id==request.args(0)).select().first()
item.update_record(status='pending')
item.seller = db(item.created_by==db.auth_user.id).select().first()
purchase = db.purchase.insert(
status = 'pending',
item = item.id,
amount = item.current_price,
currency ='USD',
item_amount = item.current_price,
payment_method = 'paypal',
recipient_id = item.seller.email)
paypal = local_import('paypal', reload=True)
row = db(db.purchase.id==purchase).select().first()
res = paypal.setec(paypal_config, row)
if res['ACK'][0]=='Success':
session.recipient_id = item.seller.email
token = res['TOKEN'][0]
url =
'https://www.paypal.com/cgi-bin/webscr?cmd=_express-checkout&useraction=commit&token='
redirect('%s%s' % (url, token))
else:
return dict(res=res)
def paypal_return():
token = request.vars.token
recipient_id = session.recipient_id
paypal = local_import('paypal', reload=True)
payment = paypal.getec(paypal_config, token, recipient_id)

invoice = int(payment['PAYMENTREQUEST_0_INVNUM'][0].split('-')[1])
purchase = db(db.purchase.id==invoice).select().first()
