When using the Postman Chrome App with the Interceptor extension it's easy to reuse the browser's cookies in order to log into an app and then call the services within.
Since moving to the Postman standalone app, this process has become somewhat manual. After logging in from the browser, I have to access the JSESSIONID cookie in the developer tools and copy its value over to postman.
When my session expires I need to repeat the process.
I would like to automate this synchronization or at least understand how I could obtain the new authenticated value in postman. It's important to note that none of the authentication mechanisms available in Postman work with my app which is why the manual login in the browser is necessary.
You can get JSESSIONID cookie in Postman Standalone in similar way your browser do it - by send proper requests (probably POST "login" request with user credentials) to server

I need to perform one app that is signed in via login.microsoftonline.com, but I get this error "We can`t sign you in your browser is currently set to block cookies. you need to allow cookies to use this service." maybe someone else has experienced something similar.
I tried changing HTTP Cookie Manager type from standart to others, also I used CookieManager.save.cookies with true and false but nothing worked.

You're not supposed to have the request to login.microsoftonline.com as the very first request in your JMeter script.
My expectation is that you're trying to test an application which uses Microsoft Identity Platform as authentication provider so depending on your application auth flow you need to pass some parameters to this login.microsoftonline.com page and the parameters need to be extracted from the previous request.
So try starting with your application login page and I believe you should be redirected to the login.microsoftonline.com with valid cookies and appropriate parameters
Single page application with specific organizational service accounts uses microsoft authorization (2.0).
To pretend in JMeter as user working with this application, it is enough to have Bearer access_token and then pass this Bearer in header of JMeter script requests.
I can manually login with user credentials in browser, get Bearer and set up it as variable in JMeter in API requests headers and successfully continue to work with application functionality.
Also I can login in WebDriverSampler (and I suppose, can emulate with WebDriverSampler another user's actions with application like in "browser").
What is the simplest and shortest way, having all above, to get Bearer somehow for API calls in a script without time-consuming or programming-oriented complex solutions? Is it possible somehow to use WebDriverSampler requests for parsing Bearer?
On this stage, the goal is to collect (and generate) Bearers, which have long time of life, with intention to use this set of Bearers for multi-session JMeter "users" later. (Because users amount is under cost constrtaints with users service accounts, i.e. I have 1 provided user only).
Will be very appreciated for grace tips and advices with such kind of problem.
It should be possible to use i.e. BrowserMob Proxy for capturing the traffic between the browser orchestrated by the WebDriver Sampler and the backend, this way you will be able to extract Authorization header value and i.e. store it into a CSV file for later re-use.
In general it should also be possible to replicate the browser's authentication flow with JMeter's HTTP Request samplers as browsers don't do any magic, they just send HTTP Requests and display the responses so well-behaved JMeter test should generate the same network footprint as the real browser does
We have developped a SPA SaaS and went to a soft production launch recently.
Everything was fine until one of our customers told us they had trouble using the app.
Once they open the app, the first request to our backend triggers their proxy credential prompt. Hopefully on the login request.
They have to enter their proxy credentials to let the request go. All subsequent requests are passing properly and they can use the app.
The problem is:
When they stop using the app, close the browser and then come back the day after, the persistent login tries to connect them to our backend, but the proxy credentials prompt is not triggered and the request fails. All subsquent requests fail also.
For it work again, they have to delete all app data in chrome (so the service worker is unregistered, the localstorage and cache are cleared). The next api call will trigger their proxy credentials prompt and they will be able to work again.
So is there any way for the app to know if the proxy is set or not ? Any way of triggering the proxy prompt if not set or whatever ?
I don't exactly know how those proxies work and we have zero access to the proxy settings.
It surely is something with the credentials expiration after some time but that's all we can figure out right now. Maybe we could monitor some params in the request headers ?
We are using VueJS with axios for the requests.
My guess is when user session credentials get expired, your UI is not handling redirection to login page. When the user login for the first time you should store that the user has logged in successfully in browser localstorage. If your server returns 401 error code, you can delete the flag and redirect the user to login page. You can achieve that using meta fields in router.

I have django rest framework based app, where i am using session based authentication. All apis need session authentication to return results otherwise it will give 403.
App has login flow where user login and session is set under cookie and all apis authenticated after that.
Now i am building chrome extension for same app where i need to make one of the rest api call. since user is already logged in browser so i am assuming that i can make the api call from chrome extension. but when i make the api call from chrome extension its returning 403. I am using fetch to perform request.
I am new in developing chrome extension so i am not able to figure out how to authenticate api call from chrome extension since user is already logged in browser.
I tried ajax request and fetch request and also set the permission in manifest.json.
fetch(url, {
credentials: 'include'
})
My application has a microsoft authentication on it before logging into it & I have recorded script but when I am running it, it is showing me access denied error everytime.I have set authentication manager but still same error. See image attached.
I have tried HTTP Authentication Manager & provided login username & password.
Most probably your application uses OAuth therefore it is neither something you can really record and replay nor handle with the HTTP Authorization Manager.
Depending on your application setup you will either need:
To perform correlation of the query parameters
Or to pass the relevant Authorization Bearer token via HTTP Header Manager. The process of obtaining the token can be different depending on your application login chain implementation, check out How to Run Performance Tests on OAuth Secured Apps with JMeter article to get a couple of ideas regarding bypassing 3rd-party provider login challenge in JMeter tests.
Check if you can provide the auth credentials as parameter of the requests.
for example www.abc.com?username=abc&password=abc. Replicate the same with Jmeter
Use Fiddler (or you can get away with browser dev tools if you don't mind searching manually) and log in manually via your browser.
Check the request(s) that are submitted to Microsoft for tokens/GUIDs and search for where the browser got those strings from (it'll be in one of the previous requests' responses' bodies or redirect URLs. In Fiddler you can use the find function on responses, browser dev tools you'll have to find it manually).
You can then use a JMeter Regular Expression Extractor post-processor (or any of the other post processors you prefer) to extract that string from the earlier request into a variable.
In your login request you can then use the value of that variable (if you used regular expression post-processor with a capture group the first group's value will be ${variable_g1}
You'll probably have an anti-forgery value that you can extract from the HTML of the login page which needs to be submitted with the username and password and then in the response you'll get a cookie set and potentially JWT token in the response body/URL.
