I am trying to query Azure Table storage without using NodeJS. If I run the query on the whole table (sales) I get all the results fine, but when I want to filter on Partition Key and RowKey I get the error "Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature"
Here is my code
var storageAccount = 'xxxxxxxxx';
var accountKey = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
var date = new Date();
var UTCString = date.toUTCString();
var dataToEncode = UTCString + "\n" + "/" + storageAccount + "/sales";
var hash = CryptoJS.HmacSHA256(dataToEncode, CryptoJS.enc.Base64.parse(accountKey));
var strSignature = CryptoJS.enc.Base64.stringify(hash);
var auth = "SharedKeyLite " + storageAccount + ":" + strSignature;
var tableName = 'sales';
var pk ="CAR1748"
var rk = "1";
var queryString = encodeURIComponent(tableName + "(PartitionKey='" + pk + "',RowKey='" + rk + "')");
var path = "https://" + storageAccount + ".table.core.windows.net/" + queryString ;
var header = { "Accept" : "application/json;odata=nometadata", "x-ms-date" : UTCString , "Authorization" : auth , "x-ms-version": "2021-06-08", "DataServiceVersion": "3.0;NetFx","MaxDataServiceVersion": "3.0;NetFx" };
try {
var response = https.get({
url: path,
headers: header
});
context.response.write(response.code);
} catch (e) {
//context.response.write(response.code);
context.response.write(response.body);
return true;
}
Based on the documentation provided here, you would need to include the query string in your data to encode.
So your code would be something like:
var storageAccount = 'xxxxxxxxx';
var accountKey = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';
var tableName = 'sales';
var pk ="CAR1748"
var rk = "1";
var date = new Date();
var UTCString = date.toUTCString();
var queryString = encodeURIComponent(tableName + "(PartitionKey='" + pk + "',RowKey='" + rk + "')");
var dataToEncode = UTCString + "\n" + "/" + storageAccount + "/" + queryString;
var hash = CryptoJS.HmacSHA256(dataToEncode, CryptoJS.enc.Base64.parse(accountKey));
var strSignature = CryptoJS.enc.Base64.stringify(hash);
var auth = "SharedKeyLite " + storageAccount + ":" + strSignature;
var path = "https://" + storageAccount + ".table.core.windows.net/" + queryString ;
var header = { "Accept" : "application/json;odata=nometadata", "x-ms-date" : UTCString , "Authorization" : auth , "x-ms-version": "2021-06-08", "DataServiceVersion": "3.0;NetFx","MaxDataServiceVersion": "3.0;NetFx" };
try {
var response = https.get({
url: path,
headers: header
});
context.response.write(response.code);
} catch (e) {
//context.response.write(response.code);
context.response.write(response.body);
return true;
}

I have a node-red flow from where I want to post a json object to Azure CosmosDB using the CosmosDB REST API. Below is a code snippet in JavaScript (node red function node) for building the POST request and as well generate the signature. I get response from Cosmos that the message is not properly formatted: "HTTP Error 400. The request is badly formed". Does anyone know what I´m doing wrong here? I´v included an image for the HTTP Request where we can see the headers and json body.
const { crypto } = context.global;
function getAuthorizationTokenUsingMasterKey(verb, resourceType, resourceId, date, masterKey) {
var key = new Buffer(masterKey, "base64");

(resourceType || "").toLowerCase() + "\n" +
(resourceId || "") + "\n" +
date + "\n" +
"" + "\n";
var body = new Buffer(text, "utf8");
var signature = crypto.createHmac("sha256", key).update(body).digest("base64");
var MasterToken = "master";
var TokenVersion = "1.0";
return encodeURIComponent("type=" + MasterToken + "&ver=" + TokenVersion + "&sig=" + signature);
}
var url = "https://myurl.documents.azure.com/dbs/FamilyDatabase/colls/FamilyContainer/docs/"; //id here???

What I'm trying to achieve is a Zapier Code (JS) action to preform a Twitter reply to a given status ID with a given text .
I'm already using the functioning Zapier (JS) Code action offered by #KayCee which preform a POST favorites/create and would like to modify it so it would preform a reply action to any given status_id using the POST statuses/update (in_reply_to_status_id) as instructed by Twitter API.
Here is #KayCee's code with the modifications I made to preform a reply:
// This code requires that you set the ID of the tweet that you want to reply to as an input variable called "reply_to_id" and the text you wish to reply as an input variable called "status_text". Learn more at https://zapier.com/help/code/#data-variables
// INSTUCTIONS FOR SETTING THESE REQUIRED VARIABLES: After you create a new app at https://apps.twitter.com/, click on the name of the app to open it. Then, select the "Keys and Access Tokens" tab.
var twitterApplicationConsumerKey = 'CONSUMERKEY';
var twitterApplicationConsumerSecret = 'CONSUMERSECRET';
var twitterApplicationAccessToken = 'ACCESSTOKEN';
var twitterApplicationAccessTokenSecret = 'ACCESSTOKENSECRET';
// That's it. No need to edit anything below.

For some reason, I keep on getting error message: "Could not authenticate you" although the same code worked for performing a "like".
Not sure what am I doing wrong?
This JS code for Zapier by #ReganStarr enables to generate a "like" action for any given tweet_id passed as a variable. I'm trying to modify it to generate a "retweet" action.

I thought that by modifying this line:
var apiUrl = 'https://api.twitter.com/1.1/favorites/create.json?id=' + tweetId;
to this:
var apiUrl = 'https://api.twitter.com/1.1/statuses/' + tweetId +'.json';
as instructed by Twitter here, would be enough but it doesn't work :-(
What am I doing wrong?
I believe the endpoint mentioned on Twitter is different than the one you've changed it to. Could you try changing the apiUrl to the following?
var apiUrl = 'https://api.twitter.com/1.1/statuses/retweet/' + tweetId +'.json';
or (for better readability)
var apiUrl = `https://api.twitter.com/1.1/statuses/retweet/${tweetId}.json`;
I haven't tested this but it looks like the cause of the issue. Please also post the error you get in case this fails.
UPDATE:
The SignatureBaseString and the SignatureParameterString need to be changed as well.
var twitterApplicationConsumerKey = 'MyTwitterConsumerKey';
var twitterApplicationConsumerSecret = 'MyTwitterConsumerSecret';

I have recently came across this JS code for Zapier by #ReganStarr to create a "like tweet" action for any given tweet_id. I'm no expert but it sure looks fine (no error messages either), nevertheless, for some reason it doesn't work!
Would appreciate a lot if an experienced Zapier + JS eye can identify why isn't it working.
here is the code:
var twitterApplicationConsumerKey = 'MyTwitterConsumerKey';
var twitterApplicationConsumerSecret = 'MyTwitterConsumerSecret';
var twitterApplicationAccessToken = 'MyTwitterAccessToken';
var twitterApplicationAccessTokenSecret = 'MyTwitterTokenSecret';

Thanks :-)
I just tried the code you posted and it worked for me.
You might double-check that you have your Access Levels set to "read and write" for your app at https://apps.twitter.com/ so that the 4 variables you include at the top of your code have the correct permissions.
And also make sure that you pass in tweet_id in the Input Data of the Zapier code step. (screenshot)
I need to send HTTP request to AWS with signed request via Javascript. Sadly I cannot use the AWS SDK JS as its either for Node.js or browser, but I need to run it from Rhino JS environment.
seems I am doing something very wrong as I get whatever I do same result - AWS was not able to validate the provided access credentials.
:(
The code I am using is same as the one Amazons is using as example (but in Python). I am using only one external lib so I can use HMCA &SHA.
Any help is much appreciated (and needed as I am struggling for days by now...), so yeah - help!
Thanks is advance!
Cheers,
Joro

Check the URL construction. For one, the request_parameters have some missing and misplaced delimiters.
var request_parameters = 'AWSAccessKeyId=' + access_key +
'&Action=RunInstances&ImageId=ami-b770fbd8';
In addition to inspecting and testing the resulting URL, you might also try to simply the syntax to make it easier to check and update. Just as an example, the following
var credential_scope = datestamp + '/' + region + '/' + service + '/' + 'aws4_request';
var string_to_sign = algorithm + '\n' + amzdate + '\n' + credential_scope + '\n' + new Hashes.SHA256().hex(canonical_request);
could be written as follows (which seems easier to check to me):
var credential_scope = [
datestamp,
region,
service,
'aws4_request'
].join('/');
var string_to_sign = [
algorithm,
amzdate,
credential_scope,
new Hashes.SHA256().hex(canonical_request)
].join('\n');
