 Description   

Steps to reproduce:

  1. Create an item with type HTTP agent
  2. Paste JSON request body into 'Request body' section
  3. Change a value in the body to a user macro
  4. Monitor response

Result:

The result I get from the endpoint when I use a macro is blank or '{}', suggesting that the JSON data posted is valid, but the "url" value is incorrect and does not match any records in Google Safe Browsing API.

If I change my '{$URL}' macro within the JSON body to the exact text I put in my user macro, it works and the responseI get is a match from Google Safe Browsing API.

I'll include a screenshot of both the JSON body including the macro, as well as a screenshot of the straight text.

I'll also include a screenshot of latest data, which shows where I change it to use the straight text URL and it begins to work.

Expected:
I expect the macro to send the url in place of the macro unformatted and result in a match.

 

I've tried:

Finding logs within the Google Safe Browsing URL that show what the request body contains, but I don't think this is possible.

I've also tried finding logs of what Zabbix is actually sending, but couldn't find any way to do this either after a lot of searching.

 

I've tried sending as 'Raw data' as well as 'JSON data' within the item config.

 

If there is a way to debug this within Zabbix itself, I'd love to get some more info on what it's actually sending in place of the macro placeholder.

Hello!

I've tried to reproduce the issue and I could not. I've installed Zabbix 4.0.19 on Ubuntu 18 with postgres DB suport. Used HTTP agent to get information from local API. My JSON is:

{
    "jsonrpc": "2.0",
    "method": "host.get",
    "params": {
        "filter": {
            "host": "{$TEST_SERVER_NAME}"
        }
    },
    "auth": "d881de82305ed43ee165bcf1ef2d28fa",
    "id": 1
}

Here I passed filter value as a macro. And it worked correctly for me.

Better late than never.

I'm using Zabbix 7.2 and phased the same issue.

What worked for me is to include the macro without the double quotation mark and on the value of the macro include said double quotation mark.

In my case I was working with an API (I can't share it do to security concerns) that required a range of time, also on grapql, and the following solved the issue:

Macro Value
{$TO} "2025-03-12T16:03:29.043Z"
{$FROM} "2025-03-05T16:03:29.043Z"

So in the body it would look something like this:

    "variables": {
        "from": {$TO},
        "to": {$FROM}
    }
