How can I create a new card with multiple members by GAS

[Deleted user]

In the following URL, It is enough to create a new card with multiple members by assigning a array whose element is the ID of members by strings.

https://developer.atlassian.com/cloud/trello/rest/api-group-cards/#api-cards-post

---------------------------

idMembers

Array<string>

Comma-separated list of member IDs to add to the card

---------------------------

But, I can't create new card in this way, and the error is {"message":"Invalid objectId","error":"ERROR"} .

How can I create ? It is helpful to show a sample code to do this. 

My code is as follows:

var payload =
{"key": "XXXXXXXXXXXXXXXXXXXXXX", 
"token": "XXXXXXXXXXXXXXXXXXXXXX",
"idList" : "XXXXXXXXXXXXXXXXXXXXXX",
"name" : "aaa",
"idMembers": ["Mr. aaa","Mr. bbb"],

var option =
{"method":"POST",
"payload":payload
};

UrlFetchApp.fetch(URL,option);

@[deleted] the idMembers needs to be a comma separated list of member IDs, not member names or usernames. 

Here's an example written in Trellinator:

Here's the implementation of Card.create:

Thank you for your answer.

I have retried in the following way by referring URL above:

var payload =
{"key": "XXXXXXXXXXXXXXXXXXXXXX", 
"token": "XXXXXXXXXXXXXXXXXXXXXX",
"idList" : "XXXXXXXXXXXXXXXXXXXXXX",
"name" : "aaa",
"idMembers": "Mr. aaa's ID,Mr. bbb's ID", // not array

var option =
{"method":"POST",
"payload":payload
};

UrlFetchApp.fetch(URL,option);

In this way, no error has occurred and I can get the result what I wanted.

Very thank you !!
