Masalah lembar Google Mailchimp dengan kunci api

Semua variabel mengembalikan nilai yang benar tetapi respons urlfetch mengembalikan 403 atau 401 (akses ditolak).

Keluaran log pertama:

 var payload = {
    "apikey": API_KEY,
    "filters": {
        "sendtime_start": REPORT_START_DATE,
        "sendtime_end": REPORT_END_DATE
    }
};
Logger.log(payload );

Keluaran log kedua:

var params = {
    "method": "POST", //what MC specifies
    "muteHttpExceptions": true,
    "payload": payload,
    "limit": 100
};
Logger.log(params);

Keluaran log ketiga:

var apiCall = function(endpoint) {

    //issue with syntax here?

    var apiResponse = UrlFetchApp.fetch(automationsList, params);
    var json = JSON.parse(apiResponse);
    Logger.log(apiResponse);
    return json;
};

Panggilan API Otomatisasi yang tidak berfungsi:

var automations = apiCall(automationsList);
var automationsData = automations.data;

for (var i = 0; i < automationsData.length; i++) {


    // are these response parameters? are these specific values getting pulled from MC - these are the type of values i want?
    var a = automationsData[i];
    var aid = a.id; // identifies unique campaign *** does this have anything to do with the call function above - it used to be as cid b/c this was for campaigns before??
    var emails_sent = a.emails_sent;
    var recipients = a.recipients;
    var report_summary = a.report_summary;
    var settings = a.settings;

    if (send_time) {

        var r = apiCall(reports, cid); // why does this have cid? but the other one didn't??
        var emails_sent = r.emails_sent;
        var opens = r.opens;
        var unique_opens = r.unique_opens;
        var clicks = r.clicks;
        var unique_clicks = r.unique_clicks;
        var open_rate = (unique_opens / emails_sent).toFixed(4);
        var click_rate = (unique_clicks / emails_sent).toFixed(4);

    }

Perulangan for bahkan tidak dijalankan karena saya mendapatkan kesalahan berikut untuk automasiData:

TypeError: Tidak dapat membaca properti "data" dari yang tidak ditentukan. (baris 82, file "Kode")

ApiResponse di sana entah bagaimana tidak berfungsi, bantuan apa pun sangat kami hargai.
