How to run this Ex(Trello API) code on Google App Script

Question

I want to use Trello API to execute on google-apps-script. but google-apps-script does not support ES6 promise.

JS

var url = "https://api.trello.com/1/cards/{idCard}/customField/{idCustomField}/item?token={yourToken}&key={yourKey}";
var data = {value: { number: "42" }};
fetch(url, { body: JSON.stringify(data), method: 'PUT', headers: {'content-type': 'application/json'}})
.then((resp) => resp.json())
.then((data) => console.log(JSON.stringify(data, null, 2)))
.catch((err) => console.log(JSON.stringify(err, null, 2)))

• You want to convert the following script to Google Apps Script.

  var url = "https://api.trello.com/1/cards/{idCard}/customField/{idCustomField}/item?token={yourToken}&key={yourKey}";
  var data = {value: { number: "42" }};
  fetch(url, { body: JSON.stringify(data), method: 'PUT', headers: {'content-type': 'application/json'}})
  .then((resp) => resp.json())
  .then((data) => console.log(JSON.stringify(data, null, 2)))
  .catch((err) => console.log(JSON.stringify(err, null, 2)))
  

• Your script works fine.

If my understanding is correct, how about this modification?

Modified script:

var url = "https://api.trello.com/1/cards/{idCard}/customField/{idCustomField}/item?token={yourToken}&key={yourKey}";
var data = {value: { text: "42" }}; // <--- Modified
var params = {
  method: 'PUT',
  contentType: 'application/json',
  payload: JSON.stringify(data)
};
var res = UrlFetchApp.fetch(url, params);
Logger.log(res.getContentText())

• Before you run the script, please modify url with your parameters.

Note:

• There are 6 custom field types like "Text", "Number", "Date", "Checkbox" and "List".
• If you use the text field for the custom field, you can use "Text" as the Custom Field Type. It's like { "value": { "text": "Hello, world!" } }.
• If you use the number field for the custom field, you can use "Number" as the Custom Field Type. It's like { "value": { "number": "42" } }.

References:

• fetch(url, params)
• /card/{idCard}/customField/{idCustomField}/item

If this didn't work, I apologize.
