The goal is to update member's information on mailchimp when anything is updated here. I already have the onEdit function working. Mailchimp API Result is Ok, and it says "throttled = no" and response = n/a. Google console response is Ok too, so I'm going mad with this code:

 function sendToMailChimp(id_customer,id_shop,id_gender,fn,ln,em,optin,date_add,last_order,num_pedidos,aov,good_experience)
 var API_KEY = 'xxxxxxxx-us10';
 var mc_base_url = 'https://us10.api.mailchimp.com/3.0';
 var mc_list_id = 'xxxxxxxxxxxx';

 var ss = SpreadsheetApp.getActiveSpreadsheet();
 var sheet = ss.getSheetByName('');
 //Header of PUT request
 var headers = 
 'Authorization': 'Basic ' + Utilities.base64Encode('username' + ':' + API_KEY, Utilities.Charset.UTF_8),

 ;

 //MailChimp API requires MD5 hash of email to identify a subscriber
 function md5(str) 
 return Utilities.computeDigest(Utilities.DigestAlgorithm.MD5, str).reduce(function(str,chr)
 chr = (chr < 0 ? chr + 256 : chr).toString(16);
 return str + (chr.length==1?'0':'') + chr;
 ,'');
 
 var emHash = md5(em.toString().toLowerCase());

 //Body of PUT request
 var payload = JSON.stringify( 
 "status_if_new": "subscribed", 
 "email_address": em,
 "merge_fields": 
 "id_customer": id_customer,
 "id_shop": id_shop,
 "id_gender": id_gender,
 "optin": optin,
 "date_add": date_add,
 "last_order": last_order,
 "num_pedidos": num_pedidos,
 "aov": aov,
 "firstname": fn, 
 "lastname": ln,
 "good_experience": good_experience
 
 );

 //put the above variables together into 'options'
 var options = 
 "headers" : headers,
 "payload": payload,
 "method" : "put",
 "muteHttpExceptions" : true
 ;
 //PUT request to specific subscriber in Mailchimp
 var response = UrlFetchApp.fetch(mc_base_url + '/lists/' + mc_list_id + '/members/' + emHash,options);
 if( response.getResponseCode() == 200 ) 
 console.info( "SUCCESS to PROD for " + em + payload);
 else 
 console.log(response);
