Example flow (important part is the input):

{
    "label": "bar",
    "description": "",
    "inputs": [
        {
            "name": "input1",
            "label": "Input 1",
            "type": "string"
        }
    ],
    "triggers": [
        {
            "description": "",
            "label": "Manual",
            "name": "trigger_1",
            "type": "manual/v1/manual"
        }
    ],
    "tasks": [
        {
            "label": "Var",
            "name": "var_1",
            "parameters": {
                "type": "STRING",
                "value": "bar"
