PayPal IPN response not getting a payKey or trackingId?

Question

I'm trying to get the whole PayPal AdaptivePayments#Pay working, that part works. I pass a bunch of stuff in, get a paykey, which I pass to the approval url:

{returnUrl: urls[:return],
 cancelUrl: urls[:cancel],
 requestEnvelope: {errorLanguage: "en_GB"},
 currencyCode: "GBP",
 trackingId: self.id,
 receiverList: {
   receiver: [{email: Rails.configuration.site_paypal, amount: self.amount, primary: true},
              {email: self.provider.paypal_email, amount: self.amount, primary: false}]
 },
 actionType: "PAY",
 ipnNotificationUrl: urls[:ipn]}

The server comes back with everything correctly, I redirect to the url, it works, I get the payment in my PayPal sandbox account for Rails.configuration.site_paypal and in the IPN history I see the message but I have no way to identify it as it doesn't contain a paykey or trackingId :(

What am I doing wrong? Ripping my hair out...

There are two types of IPN's

One is generated for the account that receives the money, based on their profile settings (It looks like that is the one you are getting)

The other is generated for the API caller (who may or may not be financially involved in the transaction). The API caller's IPN will include the PayKey.

If the API caller, and one of the receivers are the same, Make sure that you can either differentiate between the two IPN's you will receive, or that you have separate URL's for each. (The API callers is specified when making the API call, the receiver's is specified on the PayPal profile)
