Update featurescript parameters function using API

Hello there! 😀

I'm having trouble updating features using the API. I created a simple cube using a FeatureScript function

Now, I'd like to update the cube size using the API.

To do this, I tried using GET /partstudios/d/{did}/w/{wid}/e/{eid}/features to see what the feature payload looks like :

  "features": [

    {

      "type": 134,

      "typeName": "BTMFeature",
      "message": {

        "featureType": "myFeature",

        "featureId": "F1MLG2LKDU3BAgc_0",

        "name": "My Feature 1",

        "parameters": [

          {

            "type": 147,

            "typeName": "BTMParameterQuantity",

            "message": {

              "units": "",

              "value": 0.0,

              "expression": "40 mm",

              "isInteger": false,

              "parameterId": "myLength",

              "hasUserCode": false,

              "nodeId": "ZFBzFaBd6ORWRpTF"

            }

          }

        ],

        "suppressed": false,

        "namespace": "ea5bb9f50cf0e2008a0791914::mbf9fb36657c1ca6e3a0387dd",

        "subFeatures": [],

        "returnAfterSubfeatures": false,

        "suppressionState": {

          "type": 0

        },

        "hasUserCode": false,

        "nodeId": "tOEqMN8K4lG+dqq7"

      }

    }

  ],

However, when I tried updating the feature by submitting the payload to both:

  • POST /partstudios/d/{did}/w/{wid}/e/{eid}/features/updates
  • POST /partstudios/d/{did}/w/{wid}/e/{eid}/features/featureid/{fid}

It didn't work. I keep encountering errors, and I believe my main issue is related to the btType field—I'm not sure what value to use there.

Any help would be appreciated!

    btType is not required, but you are missing some other fields which are required:

    "serializationVersion": "string",
    "sourceMicroversion": "string"

    for custom features i think you also need libraryVersion, but I'm not 100% sure.

    It looks fine otherwise. When the request fails, usually there is an error message included with the response that can help solve theses kinds of issue.

    Thank you for your king help @Caden_Armstrong !

    So I tried this payload 

      -d '{
    
    "feature": {
    
        "type": 134,
    
        "typeName": "BTMFeature",
    
        "message": {
    
            "featureType": "myFeature",
    
            "featureId": "F1MLG2LKDU3BAgc_0",
    
            "name": "My Feature 1",
    
            "parameters": [
    
                {
    
                    "type": 147,
    
                    "typeName": "BTMParameterQuantity",
    
                    "message": {
    
                        "units": "",
    
                        "value": 0.0,
    
                        "expression": "40 mm",
    
                        "isInteger": false,
    
                        "parameterId": "myLength",
    
                        "hasUserCode": false,
    
                        "nodeId": "ZFBzFaBd6ORWRpTF"
    
                    }
    
                }
    
            ],
    
            "suppressed": false,
    
            "namespace": "ea5bb9f50cf0e2008a0791914::mbf9fb36657c1ca6e3a0387dd",
    
            "subFeatures": [],
    
            "returnAfterSubfeatures": false,
    
            "suppressionState": {
    
                "type": 0
    
            },
    
            "hasUserCode": false,
    
            "nodeId": "tOEqMN8K4lG+dqq7"
    
        }
    
    },
    
    "libraryVersion": 2491,
    
    "serializationVersion": "1.2.7",
    
    "sourceMicroversion": "8ed582034102bef1fc6bca42"
    
}'

    I get

    {  "moreInfoUrl": "",  "message": "La fonction ne correspond pas.",  "code": 9999,  "status": 400}

    The message translated in english is "The function does not match".

    I also tried removing libraryVersion with no luck 😓
