403 error with axios but works on postman and browser - browser

I get Nfts on magic eden with this third party api.
http://api-mainnet.magiceden.io/rpc/getGlobalActivitiesByQuery?q=%7B%22%24match%22%3A%7B%22txType%22%3A%22initializeEscrow%22%2C%22blockTime%22%3A%7B%22%24gt%22%3A1643468983%7D%7D%2C%22%24sort%22%3A%7B%22blockTime%22%3A-1%7D%7D
It responses with results on postman and browser but causes 403 error with axios in node.js.
How can I get data in node.js?
const res = await axios.get(
'http://api-mainnet.magiceden.io/rpc/getGlobalActivitiesByQuery?q=%7B%22%24match%22%3A%7B%22txType%22%3A%22initializeEscrow%22%2C%22blockTime%22%3A%7B%22%24gt%22%3A1643468983%7D%7D%2C%22%24sort%22%3A%7B%22blockTime%22%3A-1%7D%7D',
{
headers : {
"Content-Type": "application/json",
"Access-Control-Allow-Credentials": "*"
}
}
);
return res.data;

Using a proxy here won't help as they have Cloudflare protection set up against bots/scripts and it requires cookies to be present: screenshot 1, screenshot 2
You should get in touch with their support and ask for the API key (they have a public API v2 coming soon), and then use it in Authorization: Bearer <token>
Few things to note here: Their API v2 is still in works and lacks some basic features. Using their current v1 API does not require having an API key (that's what their support personnel said) but it does have bot protection against scripted attacks.
I'm hesitant to go with the API v2 since it lacks even the most basic stuff and I don't expect it to come out anytime soon. Personally, I'm looking to get in touch with people who managed to integrate the v1 into their applications, to see what necessary steps they followed in order to be able to do it.
If you managed to find some new info on that regard let me know. I'll also edit this comment in case I find out how to set up the v1 connection properly.
EDIT: managed to get it working by using the https://github.com/puppeteer/puppeteer library. Started a small headless instance of Chrome and I hit the ME API with that browser like so: screenshot 3

It can be because of CORS error.
You can use Cors proxy to fix it.
Try it,please.
const CORS_PROXY_API = `https://cors.ryanking13.workers.dev/?u=`;
const magicedenAPI = `http://api-mainnet.magiceden.io/rpc/getGlobalActivitiesByQuery?q=%7B%22%24match%22%3A%7B%22txType%22%3A%22initializeEscrow%22%2C%22blockTime%22%3A%7B%22%24gt%22%3A1643468983%7D%7D%2C%22%24sort%22%3A%7B%22blockTime%22%3A-1%7D%7D`
const { data } = await axios({
method: 'get',
url: `${CORS_PROXY_API}${magicedenAPI}`
});

How do we send post request with Kerberos authentication with axios on linux?

we are trying to call POST api to generate certificate for renewal of certification. However as per the 3rd party API reqirement, we need to validate Kerberos authentication. We have tried many thhings with no luck.
We are getting 401 unauthorized error when we are trying to run it.
Tech stack: Node.js, Javascript, Kerberos auth, Linux OS.
Code snippet:
const axios = require('axios');
const data = {
Request: "-----BEGIN CERTIFICATE REQUEST-----<csr key>-----END CERTIFICATE REQUEST-----",
CertificateTemplateName: "DBAPI1Y",
PrimaryEmail: "test#test.com"
};
axios.post('http://dummyurl.com/webapi/SubmitRequest', data, "Negotiate")
.then((res) => {
console.log(`Status: ${res.status}`);
console.log('Body: ', res.data);
}).catch((err) => {
console.error(err);
});
Tried this approach with no luck: How do I use Negotiate or Kerberos authentication with axios?
Can someone please help?
I was unable to find any traces of Negotiate support within axios. Your linked post says that in browsers it would work automatically, which is indeed true for any in-browser JavaScript (that uses Fetch or XMLHTTPRequest behind the scenes) – but the node CLI is a different world. When run through Node CLI, axios will use the HTTP client provided by Node, which doesn't do Kerberos.
It seems that you will need to implement this manually, by using the krb5 module to get a token, then telling axios to send it in the Authorization header – similar to Bearer tokens.
The following example seems to kind of work, although not very pretty – it cannot cope with '30x' redirects:
const axios = require("axios");
const krb5 = require("krb5");
// The service is "HTTP" (uppercase), regardless of the URL being http or https.
token = await krb5.spnego({hostbased_service: "HTTP#dummyurl.com"});
resp = await axios.post("https://dummyurl.com/webapi/SubmitRequest",
data,
{
headers: {
"Authorization": `Negotiate ${token}`,
},
// SPNEGO tokens are single-use, so if Axios tries to
// follow redirects, the 2nd request will be rejected
// as a "replay". So tell it to not even try.
maxRedirects: 0,
});
(I have no experience with writing "proper" Node.js code, especially async-based code, and while in theory it should be possible to use axios' transformRequest to dynamically get a new token for each request, I was unable to figure out how to do it within a sync function.)
In general, I would probably do the task in Python instead (which has well-maintained Kerberos integration using requests-gssapi or httpx-gssapi for Requests or httpx respectively).
Note that Kerberos doesn't ensure data integrity for HTTP, so you must still use HTTPS with it, otherwise someone could still simply MitM the requests.
Apart from the above approach suggested by #user1686, I have solved the problem using NTLM authentication. Specifically, I have used the httpntlm module.
By using the httpntlm package, we don't need to deal with kerberos packages as all the kerberos packages have many dependencies on node-gyp.
Thus, it's better to use some other solution apart from the kerberos related packages.
Note: This solution worked for me, but it will vary from use case to use case.

Cookie not being set from node typescript request

I'm trying to set a cookie in a node request. I have tried using packages like js-cookie, cookie-js, cookie and cookie-manager but none work.
The way I have tried it is very straight-forward, whenever my endpoint gets called i.e. https://develop.api/sess/init, I set the cookie at the very beggining of the endpoint with the following code
import * as Cookies from 'js-cookie';
export const init = async (event: APIGatewayEvent, context: Context) => {
...
Cookies.set('hello', 'hello');
...
}
As my endpoint has an auth header, I can not directly call it into my browser URL due to missing permissions, so I tried generating the fetch function with postman and pasting it into my browser's console. The function is the following
var myHeaders = new Headers();
myHeaders.append("Referer", "accepted.referer.com");
myHeaders.append("key", "somekey");
var requestOptions = {
method: 'GET',
headers: myHeaders,
redirect: 'follow'
};
fetch("https://develop.api/sess/init", requestOptions)
.then(response => response.text())
.then(result => console.log(result))
.catch(error => console.log('error', error));
Once called, my request successfully returns the expected response, but it never shows a Set-Cookie header in the network section, neither shows my cookie in the Application section.
I have to mention that I also tried looking for the cookie when making the call within Postman, but it never sets it neither.
Also, I have tried starting the application in localhost, and I have a successful response, but my cookie is still not being set.
About the package showed in the code, I said I have tried it with different ones and their implementations, so I don't think a broken package is the problem.
I'm starting to think that I have a wrong idea about how cookies work, or that someway I am completely blocking the sending of cookies within my code.
Environment
If it helps in any way, my endpoint is being hosted in a AWS Lambda application.
I know this should be trivial, but being battling with it for a day now.
I finally answered my own issue. The key here is that I'm using AWS lambdas as the proxy, therefore, the headers I were using to send the cookies were wrong, I was sending the cookies with the endpoint instead of within the lambda. Let me explain myself.
I was adding 'Set-Cookie':'cookieKey:cookieVal' in the headers of the Postman Call that I was using to test both my local and develop environments.
Instead of that, I needed to send the request within the response of the lambda for the cookies to be registered.
Please check at the following links for similar cases ->

500 error depending on data submitted in POST request

Setup: NodeJS / Express / Helmet API running on Azure App Service, CORS set to allow * so should be all fine.
Client web setup running locally on NodeJS (http://localhost:3000)
I'm trying to POST some JSON from the web client to the API for login validating purposes. Works for some requests and not others, seemingly depending on what actual values I am posting.
I've got a bit of code that uses the Fetch API to send login details and validate them, as follows:
const response = await fetch(`${baseUrl}/auth/validate`, {
method: 'POST',
mode: 'cors',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({EmailAddress: email, Password: password}),
}).catch(error => {
alert('Unable to check login');
});
If the value of email and password are both just me leaning on the keyboard, say 'skdjflsjdf' then it's all fine - the server gets my POST, validates that the login is rubbish and bounces back my error. It allows it because I get the Access-Control-Allow-Origin: * header back, so Chrome is happy.
If the value of email is an actual email address, I don't get the Access-Control-Allow-Origin: * header back and Chrome gets very upset of course.
I can't even begin to imagine how I've gone wrong here and I certainly don't seem to be able to find the right phrase to Google for a sensible answer. I'd really appreciate any help... Thanks.

Not getting data of GITHUB api using npm module sync-request

I am trying to get data of below url using sync-request module.
https://api.github.com/repos/rethinkdb/rethinkdb/stargazers
I get the data when i call it in browser or through postman.
But i am getting 403 forbidden error when calling it using sync-request in my node api.
My code looks like this.
var request = require("sync-request");
var response = request('GET', 'https://api.github.com/repos/rethinkdb/rethinkdb/stargazers', {
headers: {},
json: true
});
I am able to fetch data of many other api's but not this one. Please help.
Response body already contains the explanation:
Request forbidden by administrative rules. Please make sure your request has a User-Agent header (http://developer.github.com/v3/#user-agent-required). Check https://developer.github.com for other possible causes.
It will work like:
var response = request('GET', 'https://api.github.com/repos/rethinkdb/rethinkdb/stargazers', {
headers: { 'User-Agent': 'Request' },
json: true
});
The use of sync-request is strongly discouraged because synchronousness is achieved via a hack and may block the process for a long time.
For sequential execution request-promise can be used together with async..await.
Try to use an access token along with the GitHub API call
like this
[https://api.github.com/repos/rethinkdb/rethinkdb/stargazers?access_token=f33d1f112b7883456c990028539a22143243aea9]
As you say the API works in the browser it should not be an issue.
When you use too many calls through the GitHub API they they give the following message
{
"message": "API rate limit exceeded for 192.248.24.50. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)",
"documentation_url": "https://developer.github.com/v3/#rate-limiting"
}
To overcome this issue you can use an access token using an access token you can to access the private repositories in your account as well .
Here is the link for to get an access token [https://github.com/settings/developers]

How to authorize for Amazon's Alexa API?

I want to send a request to this Amazon Alexa API.
That page contains the last 50 activities I made with my Amazon Echo. The page returns JSON. Before you can request that page, you need to authorize your account, so the proper cookies are set in your browser.
If I do something simple as:
const rp = require("request-promise");
const options = {
method: "GET",
uri: "https://alexa.amazon.com/api/activities?startTime=&size=50&offset=-1",
json: true
};
rp(options).then(function(data) {
console.log(data);
}).catch(function(err) {
console.log(err);
});
I can send a GET request to that URL. This works fine, except Amazon has no idea it's me who's sending the request, because I haven't authorized my NodeJS application.
I've successfully copied ~10 cookies from my regular browser into an incognito tab and authorized that way, so I know copying the cookies will work. After adding them all using tough-cookie, it didn't work, unfortunately. I still got redirected to the signin page (according to the error response).
How do I authorize for this API, so I can send my requests?
I have been looking for a solution for this too. The best idea I have is to use account linking, but I haven't try it yet. Looks like ASK-CLI has interface for this also, but I can't figure it out how to use it (what is that URL?). For linking account to 3rd party server is not easy, but link it back to Amazon for the json API should not be that complicated.
