I'm using Restler's API Explorer (a fork of Swagger UI) and when I test a service call there it works fine but when I cut and paste the same URL into Chrome's Advanced REST Client I get a "403 Forbidden" error. How can that be? Is there some sort of required header parameter that needs to be passed with the request?
Here are the screen shots:
You need to get the content type right. Make sure you are sending the data as JSON (application/json)
You need to add a header
Content-Type application/json

IntelliJ has an HTTP client. When composing a file that is interpreted by the HTTP client, you can specify headers that go out to the server with the request, like so:
###
GET https://{{hostname}}/{{path}}
Content-Type: application/json
X-Auth-Token: {{x-token}}
I want to find the actual value of the token that was used to replace the variable name, seen above as {{x-token}}, but I don't see any way to obtain the request headers. The response headers are obviously available, but not the request headers. See the image below for the test results that are shown after running the HTTP client inside Intellij:
Is there a way to display the REQUEST headers?
Link to IntelliJ Documentation - HTTP Client -- the documentation seems to never mention the actual request headers that are sent over the wire, but they do discuss how to define request headers in composing the .http file type.
Check the Tools | HTTP Client | 'Show HHTP Requests History' action.
I am trying to access the token from the Response Header of the POST request. However, when I POST the request in POSTMAN it doesn’t show all the Response headers which I see on the chrome dev tool.
The KEY in the response header I am after is :
location: https://app.rm.dev/auth/callback/?token=
Also, I can see when I POST the request I receive a GET request in the chain in the Console window [image attached]. I tried but was unable to get all the Response Headers, therefore is there a way I can copy the GET request Token value from the Console window shown in the Image?
Found the solution, just needed to toggle off Auto redirect option in Postman Settings.
Created azure logic app HTTP request it gives response for normal JSON schema However, I want to attach SharePoint excel sheet when I trigger the request from Postman.
1.How to used content type or schema to download the attached file. when postman request sent.
2.is that possible to download when you hit API through logic app
3.Generated HTTP POST URL is working
For your requirement, I test it in my side. It seems we do not need to set any value for "Content-Type" in headers of response. Please refer to my logic app below:
Then when you request the logic app url in postman, please choose "Send and Download" instead of "Send".
After that, you can download the file when request the url in postman.
I been trying to debug an issue that ONLY happens on safai, I get:
Bad Request - Invalid Header
http Error 400 The request has an invalid header name
However no matter where I look for in the error console, resources, or timeline I cant look at the headers from said request.
Is there a way to get this information?
You can install http-log and point the Safari URL to localhost:7777 and it will print out what headers Safari is sending.
If you can not change the URL or just want more debugging power you should install a debugging proxy e.g. WebScarab and configure Safari to use that. You get a nice GUI where you can see all the request data: WebScarab GUI
Http-log only prints it to command line.
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:

... 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
