API - history.get does not return the item's historical value

[brenoacp]

Hi everyone!
Staff need to search the history of an item to generate some graphics in an automated report.
But the API query does not return any value. Let me give you an example:
Follow the query below using host.get
Query:

{
"output":["host"],
"sortfield": "name",
"hostids": "10129",
"selectItems":["itemid","name","key_"]
}

result:

{
"hostid": "10129",
"host": "SRVAD01",
"items": [
{
"itemid": "24687",
"name": "Host name of zabbix_agentd running",
"key_": "agent.hostname"
}

So far so good, more when I query with method history.get using for example the "itemid": "24687" the result is null:
Query:
{
"output": "extend",
"history": 0,
"itemids": "24687",
"sortfield": "clock",
"sortorder": "DESC",
"limit": 10
}

Result:

{
"jsonrpc": "2.0",
"result": [],
"id": 25
}

What was I doing wrong? Could you please help me?

"history": 0,

+ doc https://www.zabbix.com/documentation...e/history/get:

History object types to return.

Possible values:
0 - numeric float;
1 - character;
2 - log;
3 - numeric unsigned;
4 - text.

Default: 3.

Hostname is a text value, so try to use:

"history": 4,

Thanks for the feedback.
That's right, I was using the wrong object type.
