I have been trying to get an api call to Amazon SES to work for sending bulk emails. After figuring out issues with dates I'm now getting an error about the signatures mismatching. My code is below
function sendEmails() {
var template = HtmlService.createHtmlOutputFromFile('EmailTemplate.html');
var output = template.getContent();
var subject = 'Message from Mr. Bunz';
var data = JSON.stringify(
{
"Content": {
"Simple": {
"Body": {
"Html": {
"Data": output
},
},
"Subject": {
"Data": subject
}
},
},
"Destination": {
"ToAddresses": [ "example#gmail.com" ]
},
"FromEmailAddress": "no-reply#mail.example.com",
"ReplyToAddresses": [ "josh#example.com" ]
}
);
var url = 'https://email.us-west-1.amazonaws.com/v2/email/outbound-emails';
var aws_key_id = 'AKIAWLG4NO6GFEXAMPLE';
var aws_key = 'wJalrXUtnFEMI/K7MDENG+bPxRfiCYEXAMPLEKEY';
var today = new Date();
var amz_date_iso = Utilities.formatDate(today,"UTC","YYYYMMd'T'HHmmss'Z'");
var amz_date = Utilities.formatDate(today,"UTC",'YYYYMMd');
console.log(amz_date)
var signature = awsSignature(aws_key,amz_date_iso);
var headers = {
"contentType": "application/json",
'X-Amz-Date': amz_date_iso,
"Authorization": "AWS4-HMAC-SHA256 Credential="+aws_key_id+"/"+amz_date+"/us-west-1/ses/aws4_request, SignedHeaders=content-type;host;x-amz-date;, Signature="+signature
};
console.log(headers);
var options = {
"method": "POST",
"headers": headers,
"payload": data,
"muteHttpExceptions" : true,
};
apiresponse = UrlFetchApp.fetch(url,options);
console.log(apiresponse.getContentText());
}
function awsSignature(key,dateStamp) {
var regionName = 'us-west-1';
var serviceName = 'iam';
var kDate = Utilities.computeHmacSha256Signature(dateStamp, "AWS4" + key);
var kRegion = Utilities.computeHmacSha256Signature(
Utilities.newBlob(regionName).getBytes(),
kDate
);
var kService = Utilities.computeHmacSha256Signature(
Utilities.newBlob(serviceName).getBytes(),
kRegion
);
var kSigning = Utilities.computeHmacSha256Signature(
Utilities.newBlob("aws4_request").getBytes(),
kService
);
kSigning = kSigning
.map(function(e) {
return ("0" + (e < 0 ? e + 256 : e).toString(16)).slice(-2);
})
.join("");
Logger.log(kSigning);
return kSigning;
}
The exact error message is below
{"message":"The request signature we calculated does not match the
signature you provided. Check your AWS Secret Access Key and signing
method. Consult the service documentation for details."}
I've tried generating a new key/id pair with no luck. The two answers on this issue on stackoverflow I have found are here and here.
I was getting a byte array back and couldn't figure out how to convert it into the needed signature so my implementation of creating the signature is based on this post.
Would greatly appreciate any and all help.
Update
After checking my signature code with the example values provided here I noticed that at the bottom where it gives the example output it says that while those are hex representations the actual signature should be binary. Now I'm having trouble converting hex to binary in GAS

I'm trying to pull data from Airtable using Apps Scripts but all of it doesn't transfer over due to size. What do I need to add/change in order for it work?
function importCA() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var ca_sheet = ss.getSheetByName("CA")
var ca = getCA();
ca_sheet.getRange(1,1, ca.length, ca[00].length).setValues(ca)
}
function getCA() {
var ca = requestAirtable();
//console.log("ca: ", ca)
var ca_info = []
ca_info.push(["Name", "Emails", "Districts", "Job Title", "Course", "Completed", "Start Dates"])
for(i=0; i<ca.length; i++) {
var fields = ca[i].fields;
ca_info.push([
fields.Name,
fields.Emails,
fields.Districts,
fields.Title,
fields.Course,
fields.Completed,
fields.StartDates,
])
}
console.log("CA ", ca_info)
return ca_info;
}
function requestAirtable() {
var url = "[removed]"
var headers ={
"Authorization": "[removed]",
"Content-type" : "application/json"
}
var options = {
headers: headers,
method: "GET"
}
var response = UrlFetchApp.fetch(url, options).getContentText();
var result = JSON.parse(response);console.log("result: ", result)
return result.records
}
I tried to altering the line:
for(i=0; i<ca.length; i++) {
but didn't work.
If you must log it to console, you could always log it while you are pushing it to the array instead of trying to log the entire array later.
console.log(ca_info.push([
fields.Name,
fields.Emails,
fields.Districts,
fields.Title,
fields.Course,
fields.Completed,
fields.StartDates
])
I try to get data from Exchange Gate.io by app script.
This is my code:
function data() {
var key = "***"
var sec = "***"
var timestamp = Math.floor(Date.now() / 1000)
var base = "https://api.gateio.ws";
var prefix = "/api/v4"
var pat = '/wallet/total_balance'
var sign = "timestamp=" + timestamp;
Logger.log(sign)
var signature = Utilities.computeHmacSignature(Utilities.MacAlgorithm.HMAC_SHA_512, sign, sec);
signature = signature.map(function(e) {
var v = (e < 0 ? e + 256 : e).toString(16);
return v.length == 1 ? "0" + v : v;
}).join("");
var params = {
'method': "get",
'headers': {
'Accept': 'application/json',
'Content-Type': 'application/json',
'KEY': key,
'Timestamp': timestamp,
'SIGN': signature,
},
'muteHttpExceptions': true,
};
var data = UrlFetchApp.fetch(base + prefix + pat, headers=params);
Logger.log(data)
}
I get the error:
{"label":"INVALID_SIGNATURE","message":"Signature mismatch"}
The Keys is valid problem in code.
to learn more check that: https://www.gate.io/docs/apiv4/en/#retrieve-user-s-total-balances
About the official document, when I directly access the URL, an error occurs. But, when I search it on Google and access it, I could open the document. From the document, I found the documentation for the authorization and the document for "Retrieve user's total balances". And also, I found the following sample python script from the official document.
import time
import hashlib
import hmac
import requests
def gen_sign(method, url, query_string=None, payload_string=None):
key = '' # api_key
secret = '' # api_secret
t = time.time()
m = hashlib.sha512()
m.update((payload_string or "").encode('utf-8'))
hashed_payload = m.hexdigest()
s = '%s\n%s\n%s\n%s\n%s' % (method, url, query_string or "", hashed_payload, t)
sign = hmac.new(secret.encode('utf-8'), s.encode('utf-8'), hashlib.sha512).hexdigest()
return {'KEY': key, 'Timestamp': str(t), 'SIGN': sign}
host = "https://api.gateio.ws"
prefix = "/api/v4"
headers = {'Accept': 'application/json', 'Content-Type': 'application/json'}
url = '/wallet/total_balance'
query_param = ''
# for `gen_sign` implementation, refer to section `Authentication` above
sign_headers = gen_sign('GET', prefix + url, query_param)
headers.update(sign_headers)
r = requests.request('GET', host + prefix + url, headers=headers)
print(r.json())
In your situation, when this script is converted to Google Apps Script, I thought that it is your goal. When this python script is converted to Google Apps Script, it becomes as follows.
Sample script:
Before you use this script, please set the variables of key and secret.
function gen_sign_(key, secret, method, url, query_param = "", payload_string = "") {
const t = (Date.now() / 1000).toString();
const c1 = Utilities.computeDigest(Utilities.DigestAlgorithm.SHA_512, payload_string, Utilities.Charset.UTF_8);
const c2 = Utilities.formatString('%s\n%s\n%s\n%s\n%s', method, url, query_param, c1.map(b => ("0" + (b < 0 && b + 256 || b).toString(16)).slice(-2)).join(""), t);
const c3 = Utilities.computeHmacSignature(Utilities.MacAlgorithm.HMAC_SHA_512, c2, secret, Utilities.Charset.UTF_8);
const sign = c3.map(b => ("0" + (b < 0 && b + 256 || b).toString(16)).slice(-2)).join("");
return { "KEY": key, "Timestamp": t, "SIGN": sign };
}
// Please run this function.
function main() {
const key = "your api key";
const secret = "your secret";
const host = "https://api.gateio.ws";
const prefix = "/api/v4";
const url = "/wallet/total_balance";
const method = "GET";
const signature = gen_sign_(key, secret, method, prefix + url);
const headers = { "Accept": "application/json", "Content-Type": "application/json", "muteHttpExceptions": true, ...signature };
const res = UrlFetchApp.fetch(host + prefix + url, { method, headers });
console.log(res.getContentText());
}
Note:
When I tested the script using the sample variables of const key = "sample", const secret = "sample" and const t = "1234567890.123" for the python script in the official document and Google Apps Script, the same value of signature could be obtained as follows. Both requests are also the same.
603899db07ca29e5240de397b8088271b765925ba29a67267b33ad0b076fc31b0cf98d623878d57bf824b58e5336fd74f1cd101e9377816c34fec2acb9358cb2
So, when you test the above sample Google Apps Script and if an error occurs, please confirm your variables again. And, please show the error message.

The Code:
(URL is a working rest api that passes json data)
var request = require('request');
var username = "user";
var password = "pass";
var auth = "Basic " + new Buffer(username + ":" + password).toString("base64");
var url = "URL";
request(
{
method: "GET",
url : url
},
function (error, response, data) {
console.log(data);
var initial_index = Object.keys(data.sites)[0];
var product_index = Object.keys(data.sites[initial_index].products)[0];
var order_id = data.purchase_id;
var title = data.sites[initial_index].products[product_index].title;
var content = data.sites[initial_index].products[product_index].description;
var image = data.sites[initial_index].products[product_index].image;
var total_price = data.sites[initial_index].prices.final_price;
var quantity = data.sites[initial_index].products[product_index].input_fields.quantity;
var sold_by = data.sites[initial_index].info.name;
var order_status = data.sites[initial_index].status;
var datatwo = {
"status": "published",
"order_id": order_id,

"content": content,
"image": image,
"final_price": total_price,
"quantity": quantity,
"sold_by": sold_by,
"order_status": order_status
};
}
);
I receive this error when running the code. How can it be resolved?
var initial_index = Object.keys(data.sites)[0];

TypeError: Cannot convert undefined or null to object
You're not parsing the JSON (which is text) you get back. Add this at the top of your request callback:
data = JSON.parse(data);
E.g.:
request(
{
method: "GET",
url : url
},
function (error, response, data) {
data = JSON.parse(data);
var initial_index = Object.keys(data.sites)[0];
// ...
One you've parsed it, you'll have an object tree you can traverse.
I'm trying to parse JSON I recieved from an API call, but I keep running into the error "TypeError: Cannot read property "id" from undefined. (line 42, file "")" I'm relatively new to Apps Script. Any ideas on what's going on? I can get the payload back in JSON, but can't seem to parse it.
function getInfo() {
var url = "https://subdomain.chargify.com/subscriptions.json";
var username = "xxx"
var password = "x"
var headers = {
"Authorization": "Basic " + Utilities.base64Encode(username + ':' + password)
};
var options = {
"method": "GET",
"contentType": "application/json",
"headers": headers
};
var response = UrlFetchApp.fetch(url, options);
var data = JSON.parse(response.getContentText());
Logger.log(data);
var id = data.subscription; // kicks back an error
// var id = data; works and returns the whole JSON payload
var ss = SpreadsheetApp.getActiveSheet()
var targetCell = ss.setActiveSelection("A1");
targetCell.setValue(id);
}
According to the documentation here
https://docs.chargify.com/api-subscriptions#api-usage-json-subscriptions-list
it returns an array of subscriptions when you call the /subscriptions.json endpoint. So probably your data object should be handled like:
for (var i=0;i<data.length;i++) {
var item = data[i]; //subscription object, where item.subscription probably works
Logger.log(JSON.stringify(item));
}
function getInfo() {
var url = "https://subdomain.chargify.com/subscriptions.json";
var username = "xxx"
var password = "x"
var headers = {
"Authorization": "Basic " + Utilities.base64Encode(username + ':' + password)
};
var options = {
"method": "GET",
"contentType": "application/json",
"headers": headers
};
var response = UrlFetchApp.fetch(url, options);
var data = JSON.parse(response.getContentText());
for (var i = 0; i < data.length; i++) {
var item = data[i]; //subscription object, where item.subscription probably works
Logger.log(JSON.stringify(item));
var subscriptionid = item.subscription.id;
}
var ss = SpreadsheetApp.getActiveSheet()
var targetCell = ss.setActiveSelection("A2");
targetCell.setValue(subscriptionid);
}
I have this string in which i need to re-structure using JavaScript.
Label=11121212&TopicArn=test&AWSAccountId.member.1=YYYYYYY&ActionName.member.1=createTopic&Action=AddPermission&Version=2010-03-31&AWSAccessKeyId=XXXXXXXXX&SignatureVersion=2&SignatureMethod=HmacSHA1&Timestamp=2012-05-02T16%3A06%3A09.000Z&Signature=C3uIh%2Bz%2Fik
For this example, AWSAccessKeyId should be the first part of the string and label should be 2nd last. There are others as well, similar to this.
Expected output --AWSAccessKeyId=XXXXXXXXX&AWSAccountId.member.1=YYYYYYYYY&Action=AddPermission&ActionName.member.1=Publish&Label=ios-sns-permission-label&Signature=dEaNL0ibP5c7xyl4qXDPFPADW0meoUX9caKyUIx1wkk%3D&SignatureMethod=HmacSHA256&SignatureVersion=2&Timestamp=2012-05-02T00%3A51%3A23.965Z&TopicArn=arn%3Aaws%3Asns%3Aus-east-1%3A335750469596%3AiOSGoesWooooo-1335919882&Version=2010-03-31
Code that creates this incorrect string
exports.generatePayload = function(params, accessKeyId, secretKey, endpoint) {
var host = endpoint.replace(/.*:\/\//, "");
var payload = null;
var signer = new AWSV2Signer(accessKeyId, secretKey);
params = signer.sign(params, new Date(), {
"verb" : "POST",
"host" : host,
"uriPath" : "/"
});
var encodedParams = [];
for(var key in params) {
if(params[key] !== null) {
encodedParams.push(encodeURIComponent(key) + "=" + encodeURIComponent(params[key]));
} else {
encodedParams.push(encodeURIComponent(key));
}
}
payload = encodedParams.join("&");
return payload;
}
I tried putting this in an array and restructure it but it didn't work for me.
Please advice how this can be done easily using JavaScript
exports.generatePayload = function(params, accessKeyId, secretKey, endpoint) {
var host = endpoint.replace(/.*:\/\//, "");
var payload = null;
var signer = new AWSV2Signer(accessKeyId, secretKey);
params = signer.sign(params, new Date(), {
"verb" : "POST",
"host" : host,
"uriPath" : "/"
});
var encodedParams = [];
if(params["AWSAccessKeyId"] != null)
{
encodedParams.push(encodeURIComponent("AWSAccessKeyId") + "=" + encodeURIComponent(params["AWSAccessKeyId"]));
}
if(params["AWSAccountId.member.1"] != null)
{
encodedParams.push(encodeURIComponent("AWSAccountId.member.1") + "=" + encodeURIComponent(params["AWSAccountId.member.1"]));
}
//other_ifs_for_param_keys_here
payload = encodedParams.join("&");
return payload;
