 +==== In url with HTTP GET ==== 
 +The requests must be made with HTTP POST with Calaos v2.  Calaos v3 also supports HTTP GET and it is therefore possible to send a request directly in the url. 
 +  * Get the config: https://calaos_server_ip/api?cn_user=XXX&cn_pass=XXX&action=get_home 
 +  * Get a picture from a camera: https://calaos_server_ip/api?cn_user=XXX&cn_pass=XXX&action=camera&type=get_picture&id=input_57_output_32 
 +  * Set an output: https://calaos_server_ip/api?cn_user=XXX&cn_pass=XXX&action=set_state&id=output_7&value=true 
 +  * Set an intern variable: https://calaos_server_ip/api?cn_user=XXX&cn_pass=XXX&action=set_state&id=intern_4&value=true 
 +  * Read a variable : https://calaos_server_ip/api?cn_user=XXX&cn_pass=XXX&action=get_state&items=output_21,output_25 
 +That allows an external system that only supports HTTP GET to easily communicate to Calaos. 
 +==== HTML Page ==== 
 +Calaos v3 includes a debug web page to test the POST and Websocket requests.  It allows to easily verify the format of the JSON data to send. 
 +We need first to activate the debug mode with following command: 
 +calaos_config set debug_enabled true 
 +or directly add it in the file ///etc/calaos/local_config.xml//
 +The page is then accessible from https://calaos_server_ip/debug or http://calaos_server_ip:5454/debug .
