How to do it via an API call?

You could use a webhook on the start event. That would give you a REST api that you could start.
You can read how to do it here: Start a Camunda Platform 8 Process via REST with Webhooks | Camunda

Hi @savi003,

additional to @Niall’s hint, you can use any client and send the createProcessInstance command: Zeebe API (gRPC) | Camunda Platform 8 Docs.

Here is an example for the java client: Create a process instance | Camunda Platform 8 Docs
and here for the command line client zbctl: Getting started with the CLI client | Camunda Platform 8 Docs

Hope this helps, Ingo

I added the files in the sample GitHub - camunda-community-hub/camunda-8-code-studio: This repository contains all assets for the Camunda Platform 8 related Code Studio events to my project in camunda, and the change is I added a webhook to start the process, I am not sure is that the correct way, The data needed to start the process via the Camunda UI is
{
“person_uuid”: “test2”,
“employment_category”: “critical infrastructure”,
“age”: 25
}
but after deploying it webhook is not starting
