Jmeter header manager reuse - jmeter

Im using Jmeter to write some load tests on an API secured by oAuth.
I want to be able to reuse the header manager once the bearer token has been produced from the access token call.
However when I try to move the header manager out side of the http request the call is no longer authorised. I think its because it can no longer get the bearer token.
For Post Request, when i put the header manager outside it no longer works, it only works when I put it under the request as I have done for User get request, Delete request and Put request.
How do I make the header manager reusable and therefore only manage one header manager?
Thank you.

My expectation is that this is due to clash with the HTTP Authorization Manager
Both are Configuration Elements and both obey JMeter Scoping rules
When you move HTTP Header Manager outside the HTTP Request sampler it might be the case that Authorization Header comes from the HTTP Authorization Manager
You can check which exact header value is being sent using Request -> Request Headers tab of the View Results Tree listener
Given you manually create Authorization header for your request I believe if you disable or delete the HTTP Authorization Manager your test should start working as expected as you basically don't need it.

How to pass bearer token in a request apart from Authorization manager and Header manager

I need to pass the token generated in one request into another request.
In second request,
I cannot pass the Authorization as the header because the API is not designed in a way to pass the token as header, nor Authorization manager is working as I need to pass the body and in Authorization manager I am not able to locate where to pass the body.
Is there any other way apart from Authorization manager or Header manager?
HTTP Authorization Manager generates and sends the relevant Authorization header, the header value differs depending on the protocol which is being used for the authentication/authorization from basic access control to NTLM and Kerberos
HTTP Header Manager allows you to send arbitrary HTTP headers including the aforementioned Authorization one
Unfortunately we cannot suggest how exactly you can pass the token, you need to
check the API contract or documentation, some API implementations have special documentation endpoints
contact the people who "designed" the "API"
capture the request from the real browser using browser developer tools or if it's another application use a sniffer tool like Wireshark or Fiddler

How to build test plan structure to use one Header Manager to all the HTTP Request

I am working on my test plan in JMeter but I am struggling with passing bearer token to all the requests.
I managed to set bearer as variable and pass it to another request but... I don't want to add a new Header Manager to every new HTTP Request created.
Whenever I am trying to use one Header Manager to the whole thread group, the request which is responsible for getting the auth token is failing because it uses the created bearer variable as well.
So summarizing:
I want to use one Header Manager for my whole Thread Group. How to structure should look like.
In the attachment, I am adding my current test plan structure.
Just move the Login /get Token out of the HTTP Header Manager scope
For example add a Simple Controller which does nothing apart from being a container for other test elemements and move your HTTP Header Manager and HTTP Request Samplers there:
Something like:

Override Authorization header

I am doing a testing
I have setup an HTTP Authorization Manager to manage my Basic Browser Authentication. This is declared before my HTTP request - making each HTTP request header contains
Authorization: SOMETHING sOmeGibber1SHCOdes...
As some point in my testing, I need to add a new entry in the Authorization header. So I created an HTTP header Manager and added something like:
Authorization: somethingElse #n0therGibber15hC0de...
and this overrides my existing header setup by my HTTP Authorization Manager
Question:
If I need both Authorization header - is there a workaround?
Additional info:
I tried extracting the values using regext extractor and concatenate the strings in the HTTP Header manager... does't seem to work. I think simply copying the header created by HTTP Authorization manager and putting it directly to the HTTP Header Manager is not being recognized as an authentication by jmeter.
Please be informed about JMeter Scoping Rules concept
If HTTP Authorization Manager lives at the same level with the HTTP Request samplers - it will be applied to all of them
If HTTP Authorization Manager (or HTTP Header Manager) is added as a child of a particular HTTP Request sampler - it will be applied to this sampler only
So you can "override" the "global" Authorization header value by adding a HTTP Header Manager as a child of the particular request and defining the header there:

How to pass the http request auto generated _token value (value generated under http request, not in response) to next http request in jmeter

I have a http request that auto generates '_token' value with the request(this value generated under http request only, not in the response of this request) and this '_token' value needs to be passed to the next http request header as 'authorization'. I know we can use JSON/RegEx post processor if it is in Response of the first http request. However how it be be correlated if the dynamic value is in http request.
Please suggest how can we achieve this in jmeter.
Most likely you are trying to load test an application which uses OAuth and depending on OAuth version and your application setup there could be different options. If the token is permanent - you can just put it into HTTP Header Manager, however if the token expires more or less frequently - you will need to implement OAuth flow using JMeter (in some cases you will need some extras like scripting, kick off browser to open a redirect URL or use OAuth client libraries). Check out How to Run Performance Tests on OAuth Secured Apps with JMeter article for details.
I would suggest contacting your application developers to learn about OAuth version, settings, required client id/secret, etc.

How to authenticate user when testing REST API using Jmeter

I am trying to make a script to test REST services using Jmeter.
Till now I was using Chrome’s Advanced REST Client.
My authentication request was GET and it was something like this in Advanced REST:
https://username:password#URL:portnumber
its a GET request
Now when I am using Jmeter. I tried following ways:
I added HTTP Authorization Manager and mentioned Base URL and Username/password inside it.
When I am trying to do a request then its showing me “Unauthorized”
I also tried to login using normal https request but no success.
When accessed manually, a authorization popup window appears and username and password is submitted inside this window.
Please suggest me a way for how to login using Jmeter.
Few suggestions:
Most likely you have mismatch in URL you're trying hit and the one, specified in HTTP Authorization Manager, double check it.
Add View Results Tree listener and make sure that the header like:
Authorization: Basic xxxxxxxxxxxx=
is being sent along with the request and compare it with the one, sent by the real browser.
Try switching "Implementation" of your HTTP Request samplers to HttpClient3.1, the easiest way of doing this is using HTTP Request Defaults
And finally, you can use HTTP Header Manager to send the relevant header, it's name should be Authorization and value Basic and username:password encoded in Base64. There is base64Encode function available via JMeter Plugins.
