I think I tried all the possible combinations of headers and body for my POST request in JMeter but is giving me 400 Bad Request saying that the languagePairID parameter from the body is invalid even tho it is exactly same as in Postman.
My headers:
And the request:
Meanwhile in Postman in works perfectly fine:
I tried checking and unchecking the multipart/form-data and browser-compatible headers, but nothing seems to help. I read that using Wireshark might be useful in such cases but I think for this one is not possible as it is HTTPS. I will be very grateful for any advice.
Uncheck "Use mutipart/form-data"
Remove everything from the "Body Data" tab
Switch to "Parameters" tab and put your parameters there:
Going forward be informed that you can easily convert your Postman script into JMeter:
Start JMeter's HTTP(S) Test Script Recorder
Import JMeter's certificate to Postman
Configure Postman to use JMeter as the proxy
Run your request in Postman
JMeter will capture the request and generate relevant HTTP Request sampler and HTTP Header Manager

I am working in a desktop application which contains API as well.
So when I try to hit the API using Jmeter with the local server name as localhost. I am getting the response as below
Response code:300
Response message:MULTIPLE CHOICES
Response data:
{"succeed": false, "error_message": "No data JSON received!"}
Even I tried with the Content-Type as application/json and multipart/form-data, but not worked.
Note: When I try to hit the same API using Postman, I got the 200 status.
If you're able to successfully execute the request using Postman you should be able to do this using JMeter as well. We cannot state what's wrong without seeing your Postman and JMeter configurations, just make sure that everything is the same:
request URL
request bosy
request headers
etc.
If you will send the same request - you will get the same response.
Be aware that you can just record the request from Postman using JMeter
Start JMeter's HTTP(S) Test Script Recorder
If you're using HTTPS protocol - import JMeter's certificate into Postman
Configure Postman to use JMeter as the proxy
Run your request in Postman
JMeter will capture the request and generate relevant HTTP Request sampler and HTTP Header Manager

I have setup an api in jmeter which will generate the bearer token for OAuth 2.0. When checking the request body in view result tree listener, seems like jmeter is not parsing the -Client Secret key.
request making
View Result tree - Request body
Response - 400
Please try the below,
Tried it on postman, (working fine)
Now from JMeter, (working fine)
I guess you missed the checkboxes (URL Encode?) in the request parameters in the Jmeter section
HTTP Status 400 means "bad request", one of your request parameters is not correct, like URL or request data or request headers, cross check them with browser/postman
If you're able to successfully execute the request using Postman you can just record the request from Postman using JMeter's HTTP(S) Test Script Recorder
Start JMeter proxy server
Configure Postman to use JMeter as the proxy
Run your request in Postman
JMeter will capture the request and generate appropriate HTTP Request sampler and HTTP Header Manager

In POSTMAN when i POST a URL with Headers with Body data it is working fine and getting Response as 200,but when i POST the same in J meter HTTP API request i am receiving the following Error.
Headers size in bytes: 124
Body size in bytes: 54
Sample Count: 1
Error Count: 1
Data type ("text"|"bin"|""): text
Response code: 404
Response message: Resource Not Found
If you're sending the same requests you should be getting the same responses. HTTP Status Code 404 means that URL path is not correct so you need to check the path of your URL as most probably there is a difference there. Even non-printable characters which you cannot see in JMeter GUI are encoded into their equivalents so whitespace becomes %20 so pay attention to literally everything.
In any case given you can successfully execute the request in Postman it means that you can record it using JMeter's HTTP(S) Test Script Recorder
Prepare JMeter for recording, the easiest way is using JMeter Templates Feature
once JMeter creates a Test Plan for your - expand and start the HTTP(S) Test Script Recorder
Prepare Postman for recording, configure it to use JMeter as the proxy:
Run your request in Postman
That's it, JMeter should capture the request and save it under the Recording Controller along with the HTTP Header Manager containing corresponding request headers
I am trying to implement testing POST request for my APIs using KARATE, but getting 403 - expected csrf token not found.
However, I am able to perform POST Request using Jmeter - Login to the application, perform GET request and get the XSRF Token from GET request RESPONSE HEADERS and pass it in the POST request in Header Manager in Jmeter. That way, I am able to create a new resource using POST. I am not sure why this approach isn't working in Karate.
You must be missing some header. The fastest way you can solve this is by collaborating with someone on the server-side dev team.
Refer to this example in the Karate demos that uses CSRF:
I've just started using Postman to test an API I am integrating to.
I have the following error that keeps showing up
Invalid CORS request
Note the following:
The API uses Bearer token authentication(OAuth2). I have this
working without a problem.
I do get the bearer token successfully, assign it to an Environment variable and then attempt to use it for the RESTful operations.
The problem is in the subsequent RESTful operation that uses the token.
When I use an old token (through a POST operation), it rightfully
tells me that it is expired and not authorized.
When I then generate a new one and try to run the restful call, it gives me that Invalid CORS request error.
Using cURL, I have no issues. But I am frustrated by Postman.
What I have found so far:
Using postman with Http POST requests - I don't get the part in bold
Just in case anybody else has this same problem, here is how to solve
it. Go to https://www.getpostman.com/docs/capture in your chrome
browser. Click on interceptor extension and then choose add to
chrome. Once it is added there is a new icon top right of both the
browser and postman that looks like a traffic light. In postman click
this and it turns green. Then add a header to every request going to
third light. Every header consists of the header name and a value.
Start typing over the header name and a list of allowed http headers
comes up. Choose "Origin". In the cell for value simply type the
full URL of your server. (Do not forget the 'http://' or 'https://').
What is the expected response to an invalid CORS request? - Best explanation I have seen so far on CORS errors.
The other material speaks about Access-Control-Allow-Method header, preflight requests
... and there is an illustrative Apache Tomcat flowchart of the CORS flow.
Here's the answer you found again:
Just in case anybody else has this same problem, here is how to solve it. Go to https://www.getpostman.com/docs/capture in your chrome browser. Click on interceptor extension and then choose add to chrome. Once it is added there is a new icon top right of both the browser and postman that looks like a traffic light. In postman click this and it turns green.
... With the bit in bold translated:
Then add a header to your request. The header Key should be "Origin" and the header Value should be the full URL of your server (Do not forget the http:// or https://).
Note that Chrome/Postman won't allow you to add a Header with a Key of Origin without the Interceptor plugin.
Also note that at least on my system the Interceptor icon no longer looks like a traffic light.
If your back-end service side code checks for origin of the request (just to avoid CORS attack) you may face this issues when testing your Rest API through postman.
How to Resolve this .?
You need to install a Chrome plugin called Postman Interceptor (https://chrome.google.com/webstore/detail/postman-interceptor/aicmkgpgakddgnaphhhpliifpcfhicfo?hl=en).
After successfully installing this plugin , in you Postman client you can see small icon called Postman Interceptor , you need to toggle it to turn it on.
Now you can add a Request header as below
RequestHeader Key "Origin"
RequestHeader Value "your application base URL"
Check this image
Now you should be able to over come CORS issues you are facing
Cheers !!
Just avoid using browser/chrome postman plugin. Use the desktop application instead!
Seems our server is seeing from a Postman manual HTTP POST that the orgin is invalid b/c its coming from Postman as "chrome-extension://fhbjgbiflinjbdggehcddcbncdddomop"
Not sure why or how to resolve on client/Postman side. Seems our server is correclty rejecting it as is though and issuing a 403.
Value of "Origin" header set in Postman request should be allowed in API backend. For example, using Spring Boot for API should have next:
#Configuration
public class WebConfig implements WebMvcConfigurer {
#Value("${cors.allowedOrigins}")
private String allowedOrigins;
#Override
public void addCorsMappings(CorsRegistry registry) {
registry.addMapping("/**")
.allowedOrigins(allowedOrigins)
.allowedMethods("*")
.allowedHeaders("*");
}
}
where allowedOrigins is set using application.properties property cors.allowedOrigins having comma separated list of allowed origins, eg:
cors.allowedOrings=http://localhost:8080,http://example.com
and set 'Origin' value in Postman to any url from cors.allowedOrigins
I was getting this error when testing my APIs on the postman. Even after meticulously configuring my cors. So I used Insomnia instead of Postman and it works fine. I guess sometimes postman is the problem as it needs some extra effort.
You can try new version of PostMan. To me it works after upgraded postman version from 5.5.5 to 7.36.5
