I recently created a Coresight custom symbol which gets information from the PI Web API. The problem is that I have to enter the PI Web API url and accept the SSL certificate before using this symbol. Otherwise it won't work. One workaround is to import the certificate on every client machine. However, it is impracticable in the production enviroment. I read that it is possible to configure a SSL certificate for a domain, without having to purchase one from a CA. Does anyone know some good references on how to set it up?
