How to send a GET request with JSON body in JMeter?

Question

I am facing some issues as JMeter doesn't take the JSON body passed as a parameter. I tried through postman and it was working fine but for Jmeter it is not working

I am expecting a response from get request with JSON body in Jmeter

We're not telepathic enough in order to suggest you how you can fix your "some issues" without knowing the details of the "issues"

JMeter can send the GET request with the JSON (or any other) body

If the request works in Postman and doesn't in JMeter most probably you're not sending the same requests, the most common mistake is that people forget to add a HTTP Header Manager configured to send correct Content-Type header.

Just use a 3rd-party sniffer tool to intercept requests originating from JMeter or Postman, identify the difference(s) and amend your JMeter configuration so the requests would be exactly the same. Alternatively just record the request from Postman using JMeter's HTTP(S) Test Script Recorder
