# Zabbix API — Reference for Portal Integration

Researched: 2026-07-07 | Zabbix 7.x

## Protocol

JSON-RPC 2.0 over HTTP — single endpoint:

```
POST https://<zabbix-server>/zabbix/api_jsonrpc.php
Content-Type: application/json-rpc
Authorization: Bearer <token>
```

All requests are HTTP POST to one URL. No REST endpoints, no OpenAPI spec. Well-documented, stable.

## Authentication

**API token (recommended):**
- Create in Zabbix UI: Users > API tokens
- Pass as `Authorization: Bearer <token>` header
- Or use session via `user.login` method (returns token string)

## Key Methods for Portal Integration

| Portal Need | Zabbix Method |
|---|---|
| List monitored hosts + status | `host.get` with `selectInterfaces`, `selectGroups` |
| Live CPU/RAM/disk | `item.get` with `lastvalue`, filter by host name |
| Bandwidth history | `history.get` (raw) or `trends.get` (hourly/daily rollups) |
| Active problems/alerts | `problem.get` or `trigger.get` with `value=1` |
| Acknowledge/close event | `event.acknowledge` with action parameter |
| Register new device | `host.create` with interface, template, group, macros |
| Real-time push | Zabbix webhooks (Slack, Teams, custom URL) + `action.create` |

## Example: Get All Hosts (Python)

```python
import requests, json
r = requests.post(
    "https://zabbix.example.com/api_jsonrpc.php",
    headers={"Authorization": f"Bearer {token}", "Content-Type": "application/json-rpc"},
    json={"jsonrpc": "2.0", "method": "host.get", "params": {"output": ["hostid","name","status"], "selectInterfaces": ["ip","dns","port"]}, "id": 1}
)
```

## Example: Get Live CPU for a Host

```python
host_id = "10234"
r = requests.post(url, headers=headers, json={
    "jsonrpc": "2.0",
    "method": "item.get",
    "params": {
        "hostids": host_id,
        "search": {"key_": "system.cpu.util"},
        "output": ["itemid", "name", "lastvalue", "lastclock"]
    },
    "id": 2
})
```

## Feasibility Verdict

Highly feasible. The API is mature, stable, provides all needed operations for a portal monitoring dashboard. Cloud migration is just changing the endpoint URL.
