title: JMETER Performance Testing - Dynamic Payload
body: <p>While doing performance testing via JMETER, I encountered one usecase where the POST request call is taking the dynamic data from the website. So in that case when we run our script it fails as that data is no more available on the website.</p>
  <p>Payload looks like given below. It is a POST CALL and the payload is changing everytime.</p>
  <p>{&quot;marketId&quot;:&quot;U-16662943&quot;,&quot;price&quot;:{&quot;up&quot;:98,&quot;down&quot;:100,&quot;dec&quot;:&quot;1.98&quot;},&quot;side&quot;:&quot;HOME&quot;,&quot;line&quot;:0,&quot;selectionids&quot;:[&quot;W2-1&quot;]}</p>
  <p>Could anyone suggest how we can make this payload dynamic when we create a script in JMETER?</p>
