Exporting a CA Certificate

The CA certificate on the application server can be exported as follows:

  1. Start a browser, and type the callback address in the address box. Internet Explorer is used as an example.
  2. Check the certificate. The methods for checking a self-signed certificate and non-self-signed certificate are different.

    • If the callback address uses a self-signed certificate, the message "There is a problem with this website's security certificate" is displayed. Choose Continue to this website (not recommended). > Certificate Error > View certificates.

    • If the callback address is not a self-signed certificate, choose Security Report > View certificates.
