Platform Notifications:
Tips on how to handle eBay Platform Notifications within a Rails app
====================================================================
One quick way to handle incoming notifications from eBay is to setup a Rails
controller to receive them. There are a few tricks you need to do in order to
receive them, however.
1. First, you need to create a controller.
script/generate controller Ebay
2. Next, you need to tell eBay to send all notifications to this new controller.
You can do this from script/console, if you want (just make sure that in the
console, you load the appropriate eBay4r classes)
{{{
@ebay = EBay::API.new('auth_token', 'dev_id', 'app_id', 'cert_id', :sandbox => true)
resp = @ebay.SetNotificationPreferences(:ApplicationDeliveryPreferences => {
:ApplicationEnable => 'Enable',
:ApplicationURL => 'http://' + request.env["SERVER_NAME"] + '/ebay/notification',
:NotificationPayloadType => 'eBLSchemaSOAP' },
:UserDeliveryPreferenceArray => {
:NotificationEnable => [
{ :EventEnable => 'Enable',
:EventType => 'EndOfAuction' },
{ :EventEnable => 'Enable',
:EventType => 'Feedback' },
{ :EventEnable => 'Enable',
:EventType => 'AskSellerQuestion' }
]
})
}}}
3. Finally, you need to write some controller methods to handle the incoming notifications.
{{{
def notification
# Grab the raw SOAP XML into a string
post_data = request.raw_post
# Unmarshal the XML into a SOAP object
resp = SOAP::Marshal.unmarshal(post_data)
# Now it's business as usual -- use the resp object like you would
# use any outgoing eBay call object.
case resp.notificationEventName
when 'AskSellerQuestion'
# code here
when 'EndOfAuction'
# end of auction code
when 'Feedback'
# feedback received code
end
end
}}}
Hope this helps!
