I am new to Zabbix, i am using Zabbix to monitor few REST API's. Which has the Oauth token.
I am able to get oAuth token from Zabbix items (HTTP agent) and by preprocessing steps Json path i can get access_token.
Now i am clueless how to use the token generated here in (steps) to web scenario steps (Query fields).
