Paypal IPN callback - how to?

Rails
1

I’m using Paypal to make payments through my Rails app and I have IPN
setup so that when rails receives notification from Paypal, a record is
activated. This all works fine.

However, Paypal sends the notification multiple times. I think this is
because my controller is not notifying Paypal that it has received the
IPN call. I’m using ActiveMerchant.

I tested the script on http://www.eliteweaver.co.uk/testing/ipntest.php
(which is an IPN testing environment) and it said that my script was not
posting back to them.

Here is my code:

def notify

Create a notify object we must

notify = Paypal::Notification.new(request.raw_post)

if notify.acknowledge
#record transaction details here…
begin
if notify.complete?
#do some validation and then activate record
else
#Reason to be suspicious
end

rescue => e
  #There's a bug
  raise
ensure
  #make sure we logged everything we must
end

end
render :nothing => true
end

Does anyone know how to send the callback to Paypal to inform them that
I’ve received the IPN?

That’s what the notify.acknowledge should be doing.

However, I suspect that you need to somehow modify active merchant to
use the url for that testing site instead of paypal itself.

Hi,
Did you every get your PayPal IPN script working. If so, did you use a
plugin or custom code? Would you be willing to share this code for
reference?

Thanks,
Jason
