I have the proxy supported by Postman running. I'm using this to capture requests from integration tests.
I can see the requests in the history tab, but request details do not include response data, such as http code, response body etc.
If I click send, i.e. repeat the request with Postman, then this data is displayed.
I'm really confused here, since Postman is the proxy and is able to capture the request and response both, why on earth it won't bother displaying the response data, and only display details of the request?
How do I display the response to captured requests from another process??
To provide further details: I'm using the proxy, not the interceptor because I'm making calls to localhost and interceptor won't capture those.
Here is what the UI looks like, with the giant question mark showing the empty response section :)
The entries in the history tab are generated by integration tests making calls to a development server running on localhost.
If I repeat the particular (currently selected) request by clicking the send button, it'll display the json response happily.
Postman is the latest version (as of the date and time of this post) running under WSL2 with Ubuntu 20.04
Since version 8.9, Postman now allows you to capture responses along with requests.

i am playing around with Postman to get some insight on how things work behind the curtain and ran into, what I believe, is an issue but wanted to ask before I create a new issue on GitHub.
I am intercepting the request from my browser to the same site using the Postman Interceptor to use the request values in the native app. I have cookies enabled and the site (the whole domain) whitelisted.
When I use the history to resend the same request that was captured I get an auth error that is caused by the fact that the cookies are not included in the request (found that out by checking the cURL code snippet). I believe the reason for that is, that the cookies are set under another sub domain than that the request is send to.
I will try to include some pictures to clarify. My question here is:
Am I missing something/did I set something up in the wrong way
or is this an issue and I should create an issue in the official Postman Github page
cURL request
Cookies in Postman Native App
you should see if cookie is being send not using code snippet but the console :
its indeed sending cookies ,
TLDR: React app's API calls are returning with status code 200 but without body in response, happens only when accessing the web app from some browsers.
I have a React + Django application deployed using nginx and uwsgi on a single centOS7 VM.
The React app is served by nginx on the domain, and when users log in on the javascript app, REST API requests are made to the same nginx on a sub domain (ie: backend.mydomain.com), for things like validate token and fetch data.
This works on all recent version of Firefox, Chrome, Safari, and Edge. However, some users have complained that they could not log in from their work network. They can visit the site, so obviously the javascript application is served to them, but when they log in, all of the requests come back with status 200, except the response has an empty body. (and the log in requires few pieces of information to be sent back with the log in response to work).
For example, when I log in from where I am, I would get response with status=200, and a json object with few parameters in the body of the response.
But when one of the users showed me the same from their browser, they get Status=200 back, but the Response is empty. They are using the same version of browsers as I have. They tried both Firefox and Chrome with the same behaviours.
After finally getting hold of one of the user to send me some screenshots. I found the problem. In my browser that works with the site, the API calls to the backend had Referrer Policy set to strict-origin-when-cross-origin in the Headers. However on their browser, the same was showing up as no-referrer-when-downgrade.
I had not explicitly set the referrer policy so the browsers were using each of their default values, and it differed between different versions of browsers (https://developers.google.com/web/updates/2020/07/referrer-policy-new-chrome-default)
To fix this, I added add_header 'Referrer-Policy' 'strict-origin-when-cross-origin'; to the nginx.conf file and restarted the server. More details here: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Referrer-Policy
The users who had trouble before can now access the site API resources after clearing cache in their browsers.
I am trying to write automated tests with Postman. I am new to postman automation world so sorry if the question will seem dumb.
In the api that I need to test when I send a request I immediately receive a response with a transactionID, no matter transaction succeeded or not. Along with my request I send a CallbackURL to the server where I expect the actual transaction result to be called back. The server will do a PUT request back to the CallbackURL that I have provided with the transactionID and the actual response or error.
So the question is, can I have such kind of scenarios in my postman tests?
I guess I should run a web server and expose an endpoint which will expect a PUT request and I should get the body of this PUT request in my tests to check it, and respond back to it with success.
In other words, within my script I need to perform the following actions:
Do a request to the server passing a callback URL
check the immediate response from the server and keep the returned transactionID
Have a webserver run with an endpoint that I passed as a callback URL
Expect a request to that endpoint with transactionID and actual response
Check that the response is what I actually expected
Respond to the request with success
I was thinking about Postman Mock server, but seems it is not designed for such usage.
I also think may be I can run some JS Webserver (may be nodeJS) inside the postman Sandbox...
Actually I am very new to postman testing and I am really confused about this kind of issue. Is it even possible to do this with postman or I need something else?
There are some features provided by POSTMAN which can help you to resolve your problem
When you do request to server passing callback URL it gives you transactionID in response. Save that transactionID in environment variable or global variable. Same you can do it for callbackURL.
Eg. pm.environment.set("transactionID", transactionID);
Then you can do the second request where you passed callback URL and transactionID which you have already.
In short in POSTMAN there are features like
Set global and environment variable which helps to pass some values fetched from response to another request.
call other request on success of first request
eg. postman.setnextRequest({{requestname}});
If you can mentioned your problem statement little bit in details it will be easy to answer in better way.

I want to know when I'm using IE8 open a website (like www.yahoo.com), which API will be called by IE8? so I can hook these API to capture which website that IE8 opening currently.
When you enter a URL into the browser, the browser (usually) makes an HTTP request to the server identified by the URL. To make the request, the IP address of the server is required, which is obtained by a DNS lookup of the host (domain) name.
Once the response -- usually containing HTML markup -- is received, the browser renders it to display the webpage.
More details available here: what happens when you type in a URL in browser
So, in the general case, no "API" request as such is made. (Technically speaking, you can think of the original HTTP request to the server as an API request). The sort of "API" request you presumably mean, however, is not made in this general case just described. Those requests happens when the JavaScript executing on the page makes an Ajax HTTP request (XmlHttpRequest) to the web server to carry out some operation.
I am not sure about IE8, but the "developer tools" feature of most modern browsers (including IE9 and IE10), would let you see the Ajax HTTP requests that the webpage made as it carried out different operations.
Hope this helps.
IE uses Microsoft's WinSock library API to interact with web servers.
You may want to look for a network monitoring/sniffing API, which you could use to examine HTTP requests, and determine the URLs the browser is using.
I made an application using Qt/C++ that reads some values every 5-7 seconds and sends them to a website.
My approach is very simple. I am just reading the values i want to send and then i make an HTTP POST to the website. I also send the username and password to the website.
The problem is that i cannot find out if the request is successful. I mean that if i send the request and server gets it, i will get an HTTP:200 always. For example if the password is not correct, there is no way to know it. It is the way HTTP works.
Now i think i will need some kind of a protocol to take care the communication between the application and the website.
The question is what protocol to use?
If the action performed completes before the response header is sent you have the option of adding a custom status to it. If your website is built on PHP you can call header() to add the custom status of the operation.
header('XAppRequest-Status: complete');
if you can modify the server side script you could do the following
on one end :
You can make the HTTP post request via ajax
and evaluate the result of the ajax request.
On the serve side
On the HTTP request you do your process and if everything goes accordingly you can send data back to the ajax script that called it.
solves your problem .. ?
