Dynamically Trigger the BOT using API

Help
1

I have a requirement where I have to login to a site and retrieve data dynamically as and when I receive input parameters.
Example: @10 am : Input: Lat-59deg, Long-58deg
the bot has been configured to login using a fixed username and password and retrieve data.

But I am unable to do the dynamic triggering.

I read that this can be done through Orchestrator API Call. But I was unable to do it. Can someone help me out.
