I am trying to integrate Ebay with Unify by Webgility. I am getting an error code
Security header is not valid.
The tech at Webgility says I need to contact Paypal to determine if my account is an Express Account. I cannot see what type of account it is. Can any one help me with either the integration with Paypal and Unify or how to determine if I have an express account and if not, how do I convert or get one.
