    Error: Unable to get Postback Response from Paya Exchange Gateway

    Description

    I am unable to get a Postback response from the Paya Exchange gateway. What can be causing this to happen?


    Resolution

    There may be an issue with your domain's SSL Certificate. You can use an SSL Checker or Validator to see if your domain has an SSL. This site may be helpful http://www.geocerts.com/ssl_checker (this is not a Paya site and it is not hosted by Paya) to validate SSL.

    If you are receiving this error, ‘The remote server returned an error: (500) Internal Server Error.’  This means that our server is not able to complete the postback because of an error on your end. Could be a security/firewall setting of some kind, you could speak to your system administrator who could look at the server log to find out why they cannot accept the postback.

    Below is a workaround that may be able to help:

    • Turn off Request Validation on your Response Handler page.

    In case this helps .Net Developers who are running an ASP.Net 2.0 webapp - Add ValidateRequest="false" in the Page declaration.
