Hello We use REST API communication for client-server communication assuming a local network connection. Verification of international SSL server certificates for https communication is necessary when accessing public external servers If you are using it to connect on a local network, you can skip the SSL server certificate verification process. Is this usage contrary to Apple's policy? If you do make a prediction, is there any other way other than "verifying" it? [reference] 1 Client side terminal (Windows, Mac, iOS, Android) 2 Server-side equipment (image creation equipment such as network-connectable MFPs and printers) 1 and 2 are connected in the same local network and exchange data using REST API communication.
