I am new to jmeter. I am getting authorization(access token) in the header manager and request header How should i correlate it

You need to:
Identify where the token is coming from (most probably as the response to a previous login request)
Extract it using a suitable JMeter's Post-Processor and save it into a JMeter Variable. The choice of the Post-Processor depends on the type of the response, i.e.
for HTML it makes sense to go for CSS Selector Extractor
for XML or XHTML or where CSS selectors are not too powerful - XPath2 Extractor
for JSON - JSON Extractor
for everything else - Boundary Extractor or Regular Expression Extractor
Replace the hard-coded (recorded?) value with the JMeter Variable from the previous step

In my first request I am able to extract the value using Regular Expression Extractor which is clearly visible into the debug sampler. The value is extracted by setting the following options in Regular Expression Extractor:-
Name of Created Variable:- instanceUID
Regular Expression:- "InstanceUid":"(.*?)"
Template:-$1$
Match No:-1
Default Value:- (Blank)
The value that I want to pass in the next POST request is visible as:-
instanceUID_g1=2ab5dfb8-a217-4ff2-9025-523565b7b7ad
And the body for the next HTTP POST request is set like this:-
${"iInfo":{"InstanceUid":"${instanceUID_g1}","Registry":"${Registry}"}}
When this request seen in detail inside View Results Tree looks like:-
${"iInfo":{"InstanceUid":"${instanceUID_g1}","Registry":"AAX"}}
As seen the value of ${instanceUID_g1} did not get substituted in the POST body as was for variable ${Registry} which was taken from CSV config.
Being new to Jmeter can anyone suggest what did I miss?
Most probably your Regular Expression Extractor placement is not very correct, be informed about JMeter Scoping Rules concept
If you place Regular Expression Extractor as a child of the request - it will be applied to this request only
If you place Regular Expression Extractor at the same level as several requests - it will be applied to all of them
in the latter case it will be applied 1st to 1st sampler, then to Debug Sampler, then to 3rd sampler so on 2nd step it will be overwritten, most probably that's your problem
Also it appears that you're getting the data from JSON so it makes more sense to use JSON Extractor or JMESPath Extractor
I have recorded script using BlazeMeter plugin and I want to the use access token which I receive in successful login request, in another request. My Test plan looks like as below
Thread Group : [A]
|- HTTP Sampler - Login Page
|-Regular Expression Extractor [getToken]
|-HTTP Sampler - Other Page
|-Beanshell PreProcessor[Set Header in Authorization]
Regular Expression Extractor parameters and values like below :
Variable Name : token
Regular Expression : {“access_token”:”(.+?)"
Template : $1$
Match No. : 0
Beanshell PreProcessor script like below
import org.apache.jmeter.protocol.http.control.Header;
log.info("Start");
sampler.getHeaderManager().add(new Header("Authorization","Bearer"+vars.get("token")));
log.info(vars.get("token"));
Most probably your Regular Expression Extractor fails as your quotation marks look utterly suspicious. You can double check if the token variable really has the anticipated value using Debug Sampler and View Results Tree listener combination. Also check out jmeter.log file for any suspicious entries, if your Beanshell script fails - the cause will be printed there.
The response data of the Login Page seems to be JSON therefore it makes sense to use the JSON Extractor instead of the Regular Expression Extractor. It allows using JSON Path language in order to extract "interesting" bits of data from the responses. In your case the relevant JSON Path expression would be $.access_token
Since JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting so consider migrating to the JSR223 PreProcessor and Groovy language (you can re-use the same code)
You don't even need the scripting, you can add Authorization header (as well as any other header) using HTTP Header Manager
Could you add debug sampler and try first to confirm your regular expression extractor working as expected? It should provide you the required value of token.
If your token has the required value, I will suggest you to add HTTP Header Manager config element by right clicking on HTTP sampler
HTTP Request => Add => Config Element => HTTP Header Manager
In this config element, you can visually add the Headers as below:
Please Note That:- You have not provided any space/hyphen(-) or between keyword Bear and token.

In j meter I getting Access denied for user anonymous however I change json API extractor also.
variable name='token' and j son expression =""$token":"(.+?)""
still unable to do.
Can you please help how and where I have to put j meter extractor?
It appears that your trying to extract the token from JSON and using Regular Expressions is not the best idea as extra space or line break may ruin your test. Since JMeter 3.0 there is JSON Extractor which allows extracting data from JSON responses using JSON Path language. The relevant JSON Path expression will be as simple as:
$..token
With regards to "where to put" - it depends on your application implementation, JSON Extractor obeys JMeter Scoping Rules
If you need to extract the token only once and from only one HTTP Request sampler - put the JSON Extractor as a child of this sampler.
If you need to extract the token from each and every HTTP Request sampler - you need to put the JSON Extractor to be at the same level as HTTP Request samplers.

I have generated a jmeter script.
But I'm not getting anything in response data (View tree listner).
I'm getting Response code: 302 and Response message: Moved Temporarily in response header (View tree listner) also giving the URL to which it is redirected in Location field in response header.
I want this redirected URL to be displayed in response tab.
the url i wnat in response data]1
You can fetch the URL using Regular Expression Extractor.
Add Regular Expression Extractor as a child of the HTTP Request sampler
Configure it as follows:
Field to check: Response Headers
Reference Name: JMeter Variable name of your choice, i.e. location
Regular Expression: Location: (.*)
Template: $1$
You will be able to access the extracted URL as ${location} or `${__V(location)}} where required.
See Using RegEx (Regular Expression Extractor) With JMeter article for more information on correlating dynamic values in JMeter test.
In my application while executing the first request one unique key is generated which key is required for Next all the request. let me how to automate such scenario in Jmeter.
The process should look as follows:
Add Post Processor to the first request
Configure it to extract the required value and store it into a JMeter Variable
Use JMeter Variable from step 2 in your next request.
Depending on response data type you have the following choices:
Regular Expression Extractor - for text
CSS/JQuery Extractor - for HTML
XPath Extractor - for XML and XHTML
JSON Path Extractor - for JSON
It is also possible to extract data from files i.e. if response is in PDF format, but it's a little bit tricky
Example configuration to store the whole response:
Reference Name: any suitable variable name, i.e. response
Regular Expression: (?s)(^.*)
Template: $1$
You can refer the extracted value as ${response} where required. You can also amend the regular expression to extract response part instead of the whole response. JMeter uses Perl5-compatible regular expressions, see Regular Expressions User Manual Chapter for details
You can use regular expression extractor to extract the key from the response of your first request and use the extracted key for subsequent requests. To achieve this:
Right click on the first request and add post processor: Regular Expression Extractor.
Create your regular expression and provide values in other required fields. Please refer to JMeter component reference http://jmeter.apache.org/usermanual/component_reference.html#Regular_Expression_Extractor
Extracted value will be saved in the variable given as reference name
Use this variable in subsequent requests
Here is an example test plan with results.
