Zabbix REST API's?

[Editor`]

Hi all!
Does anyone know if Zabbix has REST API's available?
Our management team is using a dashboard tool "Klipfolio" for displaying Google Analytics data and they asked us if it's possible to add server performance data from Zabbix to Klipfolio.
When I asked Klipfolio is they support Zabbix, this was their response:
"If Zabbix has REST APIs available, we can test it out through our REST/URL connector."
From their website it says: "Klipfolio can process Excel, CSV, JSON, and XML files from RESTful services".
I have very limited knowledge of API's, can anyone help me on this?
My goal is to find out whether Klipfolio will be capable of displaying results from Zabbix.
Thanks a lot!

Hi, I cannot confirm, but I was trying to write a code in Powershell and the Invoke-WebRequest did not worked, when I switched to Invoke-RestMethod it worked.
So I suppose that the api is rest.
