Not receiving paypal notifications through active merchant.

[AK]

Hi,

I was working on an app in which I need to work with ipn, but it seems it does not work well. Since there is no good documentation of this it will be great if someone can help me out here :-

def success
topup = current_user.topups.last
logger.debug "topup -------->"
logger.debug topup.amount.to_i
# raise request
details = EXPRESS_GATEWAY.details_for(topup.express_token)
logger.debug "details ------->"
logger.debug details.payer_id
# raise params[:payer_id]
response = EXPRESS_GATEWAY.purchase(topup.price_in_cents,{
:ip => request.remote_ip,
:token => topup.express_token,
:payer_id => details.payer_id
})

logger.debug "Response starts here --------->"
logger.debug response

if response.success?
amount = topup.amount.to_i
current_user.credits = current_user.credits.to_i + amount
current_user.save!
flash[:success] = "Thank you for the top up"
# @account_history = current_user.account_histories.build
# @account_history.update_attribute(:type => "Top Up", :details => "", :amount => amount, :user_id => current_user.id)
redirect_to current_user

notify = Paypal::Notification.new request.raw_post

logger.info "Notifying --------->"
logger.info notify
logger.info notify.status
logger.info "Notifying 2 --------->"
logger.info notify.acknowledge

logger.debug notify.status

if notify.acknowledge
logger.debug "Notifying --------->"
logger.debug notify.mc_gross
logger.debug notify.txn_id
end

else
redirect_to root_url
end

end

notify.acknowledge does not return anything (it is blank)

Thanks for you time.
