The format of the response can differ depending on set flags.

This chapter describes flags that can be applied to units and parts of resulting JSON which they are responsible for. If you specify several flags, then parts will be gathered into one JSON.

Unit flags:

Flag - 0x00000001

{
	"nm":<text>,	/* name */
	"cls":<uint>,	/* superclass ID: "avl_unit" */
	"id":<uint>	/* unit ID */
}

Flag - 0x00000002

You can store any data you need in custom properties.

{
	"prp":{		/* custom properties */
		<text>:<text>,	/* name: value */
		...
	},
	"pup":{		/* private and public properties */
		<text>:<text>,	/* name: value */
		...
	}
}

Flag - 0x00000004

{
	"crt":<uint>,	/* creator ID */
	"bact":<uint>	/* account ID */
}

Flag - 0x00000008

{
	"ugs":[]	/* IDs of groups, into which unit is included */
}

Flag - 0x00000010

{
	"flds":{	/* custom fields */			
		<text>:{		/* sequence number */
			"id":<uint>,	/* ID */
			"nm":<text>,	/* name */
			"vl":<text>	/* value */
		},
		...
	},
	"flds_max":<long>,	/* maximal count of custom fields (-1 - unlimited) */
}

Flag - 0x00000020

{
	"gd":<text>	/* unit GUID */
}

Flag - 0x00000040

After setting this flag you can receive messages from unit.

{}

Flag - 0x00000100

{
	"uid":<text>,	/* unique ID (hardware) */
	"hw":<long>,	/* hardware type */
	"ph":<text>,	/* phone number */
	"psw":<text>	/* password */
}

Flag - 0x00000200

{
	"cmds":{		/* commands */
		<text>:[<text>]		/* link type: array of available command types */
	},
	"cml":{
		<text>:{	/* command ID */
			"nm":<text>,	/* command name */
			"cn":<text>	/* command type */
			"lt":<text>,	/* link type */
			"cp":<text>,	/* parameters */
		},
		...
	},
	"cml_max":<uint>	/* maximal count of commands (-1 - unlimited) */
}

ТTypes of commands and links are described in the chapter Command parameters.

Flag - 0x00000400

{
	"pos":{			/* last known position */
		"t":<uint>,		/* time UTC */
		"f":<uint>,		/* message flags */
		"tp":<text>,		/* message type */
		"l":<text>,		/* location */
		"y":<double>,		/* latitude */
		"x":<double>,		/* longitude */
		"z":<int>,		/* altitude */
		"s":<int>,		/* speed */
		"c":<int>,		/* course */
		"sc":<int>		/* satellites count */
		"y2":<double>,		/* latitude, locked to road */
		"x2":<double>,		/* longitude, locked to road */
		"i":<uint>,		/* digital input state */
		"o":<uint>,		/* diggital output state */
		"p":{			/* parameters */
			<text>:<double>		/* parameter name: value */
		}
	},
	"lmsg":<text>|{}		/* last known message, if it's coordinates match coordinates from "pos" than value of this field will be equals to "dup" */
}

Message format depends on its type, all types are described in the chapter Data format: Messages.

Flag - 0x00000800

				}
			],
			"vt":<uint>,	/* validation type */
			"vs":<uint>	/* Ivalidation sensor ID */
		}
	},
	"sens_max":<long>	/* maximal count of sensors (-1 - unlimited) */
	"cfl":<uint>,		/* calculation flags */
	"cnm":<uint>,		/* mileage counter, m */
	"cneh":<uint>,		/* engine hours counter, s */
	"si":{			/* service intervals */

			"sc":<uint>	/* done times */
		}
	},
	"simax":<long>		 /* maximal count of service intervals (-1 - unlimited) */
}
}

Sensor flags, types of sensors and validation are examined in the chapter Sensors.
