Jmeter parametirisation of SAML Request, Response and Relay State - jmeter

In JMeter HTTP Samplers I have to parameterize the HTTP Sampler containing parameters for SAML Request, SAML Response and Relay State but I don't know how to do it.

In addition to your credentials you need to send the aforementioned parameters. The parameters can be found in responses for the previous requests.
You need to extract them from the previous responses using suitable JMeter Post-Processors and save into JMeter Variables
While sending the next request you need to add the variables from the previous step.
The process is known as correlation and there is a lot of information regarding it in the Internet, i.e. How to Load Test SAML SSO Secured Websites with JMeter

Possible if want to do API Load Testing using JMeter with URI info only?

My team planned to do API Performance Testing using JMeter 5.0 for my client. My client developed the API in Kubernetes. Just wondering, they gave info such as URI, HTTP Method and Content-Type only. We never have experience using URI. Are these info sufficient to do load test in JMeter? And where do I fill in these info? Is it in Config Element: HTTP Header Manager?
Because usually I only do my enablement using sample website which already provide the URL.
Do I need to ask them to provide the specific URL for this? Or URL can be extracted from URI?
Thanks.
Normally you should put:
Protocol, server name or IP and Port Number into HTTP Request Defaults, this way you will have a single configuration element having these details and in case of change you will need to introduce the change at one place only and won't have to revisit each and every HTTP Request sampler
Individual requests are defined using individual HTTP Request samplers where you need to provide URL Path and request body (if any)
Content-Type and other Headers can be provided via HTTP Header Manager, the same Scoping Rules as for HTTP Request Defaults apply, for example if you want to send application/json for all the requests just add HTTP Header Manager on the top of your Test Plan and it will add the header to all HTTP Request samplers which are at the same level as the HTTP Header Manager or lower.

Jmeter - Parameters missing

We are using the jmeter recording template to see the api requests by our unsigned app.
When we use charles as the proxy, we are getting all the urls properly.
But when we use the jmeter recording template, we get 'MISSING PARAMETERS' for all GET requests. Essentially, jmeter does not get any parameters that are sent with the GET request.
POST requests work properly.
Any advice?
For convenience JMeter stores the request parameters under "Parameters" section of the HTTP Request sampler
it's better to work with attribute-value pairs for parameterization or correlation purposes than having to edit the URL string which might be very long.
If you replay your recorded request(s) and look into Request tab of the View Results Tree listener you will see that the parameters are concatenated to protocol, domain, etc. in the URL:

Form based Authentication- Jmeter

I am testing an API endpoint for which there is a form based authentication(for additional security). Can someone suggest how to handle form based authentication in Jmeter. I tried with HTTP Authorization Manage, still my request is failing.
You basically need to submit a HTML Form by sending a HTTP POST request using JMeter's HTTP Request sampler.
Given you provide correct credentials you should be authorized for further actions.
In some cases you will need to perform correlation as you might have to provide a dynamic parameter (or several) along with the credentials as your application can use these parameters for i.e. CSRF protection or for other reasons so make sure to carefully inspect the request sent by the real browser (you can capture the original request using browser developer tools) and if there are any dynamic parameters - you should extract them from the previous response using a suitable JMeter Post-Processor
Once you successfully log in it should be enough to add HTTP Cookie Manager to maintain the user session.

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.

Using SOAP/XML-RPC request as a Monitor in JMeter

I am using jmeter to submit a few SOAP messages to the application engine. I need a monitor that can collect some of the application engine's performance statistics. But the only option to query the application statistics is to send a different SOAP message to the application.
How can I use a SOAP/XML-RPC request sampler as a monitor? I can't use HTTP request as a monitor since there's no corresponding HTTP service to retrieve monitor results.
Actually as per Creating WebService Test Plan it is recommended to use HTTP Request sampler to perform SOAP calls. HTTP Request Sampler has "Use as Monitor" checkbox
Don't forget to add HTTP Header Manager in order to send correct Content-Type and SOAPAction headers.
