Zabbix API calls can be used through the graphical user interface (GUI), no need to jump to scripting. An application to perform API calls is called Postman.


  • Available on Windows, Linux, or MAC
  • Save/synchronize your collection with Google account
  • Can copy and paste examples from the official documentation page

Let’s go to basic steps on how to perform API calls:

1st step – Grab API method user.login and use a dedicated username and password to obtain and session token:

    "jsonrpc": "2.0",
    "method": "user.login",
    "params": {
        "user": "api",
        "password": "zabbix"
    "id": 1

This is how it looks in Postman:

We recommend using a dedicated user for API calls. For example, a user called “api”. Make sure the user type has been chosen as “Zabbix Super Admin” so through this user we can access any type of information.

2nd step – Use API method trigger.get to list all triggers in the problem state:

    "jsonrpc": "2.0",
    "method": "trigger.get",
    "params": {
        "output": [
        "filter": {
            "value": 1
        "sortfield": "priority",
        "sortorder": "DESC"
    "auth": "<session key>",
    "id": 1

Replace “<session key>” inside the API snippet to make it work. Then click “Send” button. It will list all triggers in the problem state on the right side:

Postman conveniences – Environments

Environments are “a must” if you:

  • Have a separate test, development, and production Zabbix instance
  • Plan to migrate Zabbix to next version (4.0 to 5.0) so it’s better to test all API calls beforehand

On the top right corner, there is a button Manage Environments. Let’s click it.

Now Create an environment:

Each environment must consist of url and auth key:

Now we have one definition prod. Can close window with [X]:

In order to work with your new environment, select a newly created profile prod. It’s required to substitute Zabbix API endpoint with {{url}} and plot {{auth}} to serve as a dynamic authorization key:

Every time we notice an API procedure does not work anymore, all we need to do is to enter Manage environments section and install a new session tokken..
