@BK84 

The best way to capture rest-api calls is by using the developer tools available in your browser.  You can initiate the action with NiFi and capture the rest-api call that was made.  

I was able to fetch a token from my ldap-provider login in NiFi 2.0.0-M4 using below:

curl 'https://<nifi-node-hostname>:<nifi port>/nifi-api/access/token' -H 'content-type: application/x-www-form-urlencoded;charset=UTF-8' --data-raw 'username=<username>&password=<password>' --insecure


Which is no different then my NiFi 1.x version.

How have you been fetching your token?

        @BK84 
        I suggest starting a new community question for your new query.  
        When you start you r new question, please provide more detail on your ask.  Not clear what you mean by "trigger".   What is the use case you are trying to implement?

        Thank you,

        Matt
