Extract POST request body from nested select options

[giladba]

I have a module with the following Mappable Parameters:

[
	{
		"name": "target",
		"label": "Target",
		"type": "select",
		"options": [
			{
				"label": "Private",
				"value": "private",
				"nested": [
					{
						"name": "phoneNumbers",
						"label": "Phone Numbers",
						"type": "array",
						"spec": {
							"type": "text",
							"label": "Phone Number"
						}
					}
				]
			},
			{
				"label": "Group",
				"value": "group",
				"nested": [
					{
						"name": "ids",
						"label": "Group IDs",
						"type": "array",
						"spec": {
							"type": "text",
							"label": "Group ID"
						}
					}
				]
			}
		]
	},
	{
		"name": "message",
		"type": "text",
		"label": "Message",
		"required": true
	}
]

The user interface looks like this:

My goal is to send a POST request to my API with body that looks as follows:

{
    "to": <obj>,
    "body": {
        "type": "text",
        "content": "bla bla"
    }
}

where the format of <obj> is:

{
  type: "private",
  phoneNumbers: []
}

if the user selected Private, and:

{
  type: "group",
  ids: []
}

if they selected Group.

I tried to define the module’s Communication like so:

{
	"url": "/messages",
	"method": "POST",
	"body": {
		"to": "{{parameters.target}}",
		"body": {
			"type": "text",
			"content": "{{parameters.message}}"
		}
	},
	"response": {
		"output": "{{body}}"
	}
}

but it doesn’t work. The request body I get is:

{
    "to": "private",
    "body": {
        "type": "text",
        "content": "nothing special"
    }
}

Solved.

{
	"url": "/messages",
	"method": "POST",
	"body": {
		"to": {
			"{{...}}": "{{omit(parameters, 'message'))}}"
		},
		"body": {
			"type": "text",
			"content": "{{parameters.message}}"
		}
	},
	"response": {
		"output": "{{body}}"
	}
}
