Using different variables for different threads in JMeter
<p>I am trying to do some performance testing on  a REST service.I am using JMeter to do that. </p>

<p>As many REST services, my request service requires authorization token to be passed in Authorization header. </p>

<p>I want to have 5 threads which should use five different tokens to mimic five users. </p>

<p>I have a single Thread group with five threads. I've added HTTP Header Manager to add Authorization header. </p>

<p>How can I substitute each users auth token for each thread? If I use variable then threads uses same auth token.</p>

<p>Is there any better approach for this?</p>
