How to set the idValue of a customField inside a customFieldItem array ? (Using GoogleScripts)

[Filipe]

So i have a 'customFieldItems' array inside a certain card. So far i can acess any position of this array using the id of that position and using this url:

https://api.trello.com/1/cards/cardId/customFieldItems/customField_Id/?&key=api_key&token=api_token;

But inside this array there is a DropDown customField and i need to change the value of the selected option of this dropdown list(in my case this dropdown is in the position 1 of the 'customFieldItems' array).

I figured that the idValue is the id that i need to change but im not able to do that .

So far i got this:

var data = { "idValue": "624460fc7dee1f1f8c5bce68" }; // This is the new id that i want to put

var options = {

    "method": "put",

    "payload": data,

    "contentType": "application/json"

  };

The URL: 

https://api.trello.com/1/cards/cardId/customFieldItems/customField_Id/?&key=api_key&token=api_token

var response = UrlFetchApp.fetch(url,options);

You might want to check the api. From my python wrapper code it seems that the structure of should be this ...where custom_field.id is the definition id

/card/' + self.id + '/customField/' + custom_field.id + '/item

and 

post_args = {'idValue': list_field_id}

the value of idValue is the id of the option you have in that CFD.

hey @milynnus  Your solution works ! Thank you!!

I addapted to the GoogleScripts like this : 

var id_Value ='IdValue here' ;

data = { "idValue": id_Value };

      options = {

        "method": "put",

        "payload": JSON.stringify(data),

        "contentType": "application/json"

      };

var url = "https://api.trello.com/1/";

var key_and_token = "key=" + api_key + "&token=" + api_token;

var id_cfield = 'IdCustomField here';

var response =

UrlFetchApp.fetch(url + "cards/" + id_card + "/customField/" + id_cfield + 

"/item?&" + key_and_token, options);

( Ive ommited the IDs but i think its clear how this works )
