Paypal sandbox all payments are pending and all pending status is unilateral

Question

I am testing my IPN handler in the sandbox. I use my test account to send payments. All of the payments that I send are logged with this error

11/21/2014 10:50:13 AM: Error in IPNHandler.IsDuplicateID(): Cannot find table 0.<br/>
11/21/2014 10:50:13 AM: Error in IPNHandler: INVALID paymetn's parameters.

as you can see the payment_status = Pending and pending_reason=unilateral . I have disabled the "payment review" option for my account and I am using a sandbox account that I created. Some people said that the pending status is because the test account isn't verified but I am pretty sure that I did that. Any help on being able to send successful payments in a sandbox would be great! if you want to see any code just let me know. I used this site almost exactly to build my IPN handler http://www.codeproject.com/Articles/19184/Use-of-the-PayPal-payment-system-in-ASP-NET?msg=4059063#xx4059063xx

Answer 1

It seems like the receiver email "Landlordlookup@gmail.com" address you are trying to use doesn't even exist . I mean you need to make sure that you have a sandbox account with the email address "Landlordlookup@gmail.com" .

If you send the payments to an email address that doesn't exist , You will get the pending_reason=unilateral
