Autodiscovery message for active client

[vadv]

How to form messages for sending autodiscovery information to zabbix-server right?
For example for sending items I should send message this format:
{
"request":"sender data",
"data": [
{"host":"", "value":"", "key":""}
],
...
}
What should I send in case of autodiscovery message for active client?
data - is an array of hashes such as [ { "{#DISCOVERY1}":"VAL1" } ]. Is it right? What I need to specify as request?

There is no 'Autodiscovery' in Zabbix.
Can you please clarify whether you're referring to Network discovery, Low-Level discovery or Agent auto-registration?

Common information about Zabbix protocols may be found here:

I mean message from active client with autodiscovery message.
This message working for me for zbx server 2.4:
{ "key": "KEY_OF_AUTODISCOVERY_MSG",
"value": "{\"data\": [ {\"#{DISCORVERY_1}\":\"VAL_1\", ....} ] }",
"host": "fqdn"}

Again, there does not exist anything named "autodiscovery" in Zabbix!
What you're most likely referring to is sending a JSON formatted value for a Low-Level-Discovery rule via Zabbix sender protocol.

In fact the answer is: Exactly as described in the Online documentation resp. the Wiki.
But take care of proper escaping.

You could also see what what Zabbix sender would make out of it, when sending a LLD JSON value to Zabbix server:

[baz@example~]# cat /tmp/json.data
{
        "data": [{
                "{#IFNAME}": "lo"
        }, {
                "{#IFNAME}": "eth0"
        }, {
                "{#IFNAME}": "venet0"
        }]
}
[baz@example ~]# nc -l 49152 &
[1] 901645
[baz@example ~]# zabbix_sender -z 127.0.0.1 -p 49152 -s example.com -k foobar -o "$(cat /tmp/json.data)"
ZBXD▒{"request":"sender data","data":[{"host":"example.com","key":"foobar","value":"{\n\t\"data\": [{\n\t\t\"{#IFNAME}\": \"lo\"\n\t}, {\n\t\t\"{#IFNAME}\": \"eth0\"\n\t}, {\n\t\t\"{#IFNAME}\": \"venet0\"\n\t}]\n}"}]}

or a bit beautified:

{
	"request": "sender data",
	"data": [{
		"host": "example.com",
		"key": "foobar",
		"value": "{\n\t\"data\": [{\n\t\t\"{#IFNAME}\": \"lo\"\n\t}, {\n\t\t\"{#IFNAME}\": \"eth0\"\n\t}, {\n\t\t\"{#IFNAME}\": \"venet0\"\n\t}]\n}"
	}]
}

If this is not what you were asking for, then please be more specific and use the correct definitions in respect of Zabbix.
