HTTP POST call with JSON content from one identity manager

Hello experts,

First of all, I am relatively new to the One Identity manager and am on a very basic skill level with this tool.

So please excuse the nerdiness of this question and assist me if possible.

I have a requirement to automate ticket creation in our service desk portal with the help of OI when a new employee is inserted,

Basically, I need to do a simple HTTP POST call with JSON content to the service desk url with a pre-defined payload (user attributes like name, department etc)

I am clueless on how to create the HTTP Post call inside OI since I couldn’t find where in the process orchestration of designer we have the option to create the call. ( I tried to go through the documentation but I am lost to understand the starting point)

If someone could point out to me where exactly I can build the POST call, that would be helpful,

thanks
