This is in a custom PHP eCommerce application. I have no problem receiving and verifying a PayPal IPN response, but it never returns with seller protection eligibility.
This is the generated IPN submission form:
the data has been replaced with dummy data for this question, but it is legitimate data in the application

</form>
In the IPN response received, protection_eligibility is always Ineligible. This occurs with or without the sandbox. The business/recipient account is configured for seller protection.
I've tried entering generating the submission form with address information that is identical to the profile information of the sandbox customer account, and I get the same result (Ineligible).
What do I need to change in my account or submission form for this to work?
SOLUTION
no_shipping must have a value of 0 (prompt for optional shipping address) or 2 (prompt for required shipping address). Orders with no shipping cannot be eligible for seller protection.
