官网介绍：

Zabbix API allows you to programmatically retrieve and modify the configuration of Zabbix and provides access to historical data. It is widely used to:

• Create new applications to work with Zabbix;
• Integrate Zabbix with third party software;
• Automate routine tasks.

The Zabbix API is a web based API and is shipped as part of the web frontend. It uses the JSON-RPC 2.0 protocol which means two things:

• The API consists of a set of separate methods;
• Requests and responses between the clients and the API are encoded using the JSON format.
