2.2.1 Communication protocol

The following shows the communication protocols and port numbers that are used by APIs.

Communication protocol

API functions support the HTTP and HTTPS protocols. API functions use a protocol that is used by JP1/AO to communicate with a web browser. For both protocols, version 1.1 is supported. For the detailed specifications of the communication protocols, see the following standards:
- For the HTTP protocol:
  
  RFC2616
- For the HTTPS protocol:
  
  RFC2818
Port number

The default port number setting differs depending on the communication protocol and the OS of the JP1/AO server.
- When the communication protocol is HTTP:
  
  22015
- When the communication protocol is HTTPS:
  
  22016
If you want to change the port number, see the topic Procedure to change the port number in the JP1/Automatic Operation Configuration Guide.
