Invoke GitHub Actions workflow manually and pass parameters

I want to pass some dynamic parameters and invoke my GitHub Actions workflow manually (ideally via some API). Is this possible?

With the workflow_dispatch event trigger, you can do the manual triggers easily.

Flow:

on: 
  workflow_dispatch:
    inputs:
      logLevel:
        description: 'Log level'     
        required: true
        default: 'warning'
      tags:
        description: 'Test scenario tags'
