Google Sheets to Mailchimp

GSheetsToMC is a script written for Google Sheets that allows you to send edits on your spreadsheet to Mailchimp merge fields instantly. In this case, this script was written to accomodate my on-campus organization's needs (UNICEF at Illinois Tech).

At UNICEF, we use a point system to keep track of members' volunteering hours, attendance, and eligibility for prizes. This point system is updated via a private spreadsheet on Google Drive accessible only to our executive board. We also use Mailchimp for our weekly newsletters and heavily rely on merge fields to update each member about their points. The biggest problem was the lack of synchronization between Mailchimp and Google Sheets (no, we weren't interested in paying Zapier to automate the task). We often forgot to re-import the spreadsheet and thus, received complaints about outdated points from our members.

The spreadsheet's layout is as follows:

First Name	Last Name	Email	Total Points	Event 1	Event 2	More Events
Pratik	Sampat	[email protected]	5	2	3	0

gsheetstomailchimp's Issues

Everything seems to work but... no record is updated

Trying your function, it seems to solve a lot of time with API documentation. Anyway I read it and it made it work... but no update occurs on Mailchimp list.

Execution console from Google shots "Complete" (so success when executing the functions).
I had to move from onEdit to its own function name and trigger it with onEdit trigger.

And at Mailchimp latest API calls messages are always:
Result: Ok
Throtteld: --
Response: n/a

I don't know if it's because field format, but I tried just updating one single value and it doesn't get updated in mailchimp list.

Any clue about what could be wrong? Script is like this now:

function sendToMailChimp(id_customer,id_shop,id_gender,fn,ln,em,optin,date_add,last_order,num_pedidos,aov,good_experience){
var API_KEY = '3e61f4b01ca32c8258117d22b971fb82-us10';
var mc_base_url = 'https://us10.api.mailchimp.com/3.0';
var mc_list_id = '3ad825a38e';

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
  }
});

//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);
}
}

/**

  function actualiza_usuario(e) {
  var activeSheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
  var range = e.range;
  //gets Index value of row which contains edited cell (e.g. cell A60 was edited, rowedited = 60)
  var rowedited = range.getRowIndex();

  var id_shop = values[1];
  var id_gender = values[2];
  var fn = values[3];
  var ln = values[4];

  var optin = values[6];
  var date_add = values[7];
  var last_order = values[8];
  var num_pedidos = values[9];
  var aov = values[10];
  var good_experience = values[11];
  sendToMailChimp(id_customer,id_shop,id_gender,fn,ln,em,optin,date_add,last_order,num_pedidos,aov,good_experience);
  Logger.log("Enviado");
  }
  }

"Invalid Resource","status":400,"detail":"Blank email address","instance

I keep receiving this error in the execution logs when I edit a cell in my sheet. I'm not sure what I need to fix, as I do have all the variables properly aligned. Checked all over stackoverflow and my question on SO hasn't been getting responses.

Here are my vars for the mailchimp function:

var payload =  JSON.stringify({ 
"status_if_new": "subscribed", 
"email_address": email,
"merge_fields": {
    "LEAD": lead,
    "LATECOUNT": latecount,
    "CALLOFFCNT": calloffcnt,
    "WFHCNT": wfhcnt,
    "WFHOCCUR": wfhoccur,
    "WFHREMAIN": wfhremain,
    "ANNCALLOFF": anncalloff,
    "OCCURTOTAL": occurtotal,
    "USEDPTO": usedpto,
    "USEDSICK": usedsick,
    "PTOREMAIN": ptoremain,
    "SICKREMAIN": sickremain
}
});

And then this is the cadence for the the google sheet part:

else {
  //capture values specifically of the row that was edited
  var values = sheet.getRange(rowedited, 1, 1, 13).getValues()[0];
  //separate values variable
   var em = values[2];
   var email = values[2]
   var lead = values[1];
   var latecount = values[6];
   var calloffcnt = values[7];
   var wfhcnt = values[8];
   var wfhoccur = values[9];
   var wfhremain = values[10];
   var anncalloff = values[11];
   var occurtotal = values[21];
   var usedpto = values[22];
   var usedsick = values[23];
   var ptoremain = values[24];
   var sickremain = values[25];      
  sendToMailChimp_(em,email,lead,latecount,calloffcnt,wfhcnt,wfhoccur,wfhremain,anncalloff,occurtotal,usedpto,usedsick,ptoremain,sickremain);

I have the email variable twice because I was trying to find if there was a conflict with the email and subscriber hash, but anyway way I run it, I still get the blank email error.

Cannot read property "source" (line 59, file "Code")

Thank you for posting the script - it's exactly what we were looking for!

When adding the mailchimp details and trying to run the script I get:

ERR: TypeError: Cannot read property "source" from undefined. (line 59, file "Code")

On this line:
var activeSheet = e.source.getActiveSheet();

Am I missing something?

Many thanks!

TypeError: Cannot read property "source" from undefined. (line 57, file "Code")

Hi, I am trying to use your codes to manage mailchimp lists in a way more effective and tried the script you wrote but, I had this error. TypeError: Cannot read property "source" from undefined. (line 57, file "Code"). Do you have any advices on how to improve this?
