Trouble with Direct Request API request set up with optional parameters.

[ScottAndersonGQ]

I'm using postman to prepare a request.

Below is an example of a successful routing between Orlando. FL to Tallahassee FL. 
GET https://route.arcgis.com/arcgis/rest/services/World/Route/NAServer/Route_World/solve?token={{token}}&f=json&stops=-81.3753552,28.5387011; -84.3078194,30.4382702 

Now I want to add additional parameters shown here: Direct request—ArcGIS REST APIs | ArcGIS Developers. 
1) restrictionAttributeNames
2) attributeParameterValues

These should be something like:

     "restrictionAttributeNames":"Height Restriction, Width Restriction, Weight Restriction, Weight per Axle Restriction, Length Restriction, Kingpin to Rear Axle Length Restriction, Axle Count Restriction, Use Preferred Truck Routes",
    "attributeParameterValues": [
        {
            "attributeName": "Height Restriction",
            "parameterName": "Vehicle Height (meters)",
            "value": 3.6576
        },
        {
            "attributeName": "Width Restriction",
            "parameterName": "Vehicle Width (meters)",
            "value": 3.6576
        },
        {
            "attributeName": "Weight Restriction",
            "parameterName": "Vehicle Weight (kilograms)",
            "value": 10000
        },
        {
            "attributeName": "Weight per Axle Restriction",
            "parameterName": "Vehicle Weight per Axle (kilograms)",
            "value": 1500
        },
        {
            "attributeName": "Length Restriction",
            "parameterName": "Vehicle Length (meters)",
            "value": 15.24
        },
        {
            "attributeName": "Kingpin to Rear Axle Length Restriction",
            "parameterName": "Vehicle Kingpin to Rear Axle Length (meters)",
            "value": 15.24
        },
        {
            "attributeName": "Axle Count Restriction",
            "parameterName": "Number of Axles",
            "value": 7
        },
        {
            "attributeName": "Use Preferred Truck Routes",
            "parameterName": "Restriction Usage",
            "value": "Prefer_High"
        }
    ]

But I can't seem to format these properly into the request. 
1) Am I doing this right?
2) Am I forgetting some other parameter?
3) What should the request look like?

Please help! Thanks!

Solved my own questions with more research. The GET request was too much. Needed to use a POST. 
Different endpoint and documentation though. 😞
These docs better explain the body requirements.
