Pass auto increment variable in request URL and body if HTTP request in jmeter

I am having a endpoint which accepts a auto-increment integer id as part of path param and in request body also there are some keys which accepts that as well.

For example endpoint is http://foo.bar/{id}

And body is 

{
 "someid" : someno+{id passed in url},
 "some world :"fixed string" + "id passed in url"
}

I tried using __counter() directly in place of my {id}, but its not working and in when debugging found that its not replacing the value and its coming as literal only.

4 years passed, I jmeter changed a little, so let me give another detailed answer:

1.create a test plan 2.create a thread group under this test plan enter image description here 3.create a http request under this "thread group"

enter image description here

4.under this "http request", create a "loop controller" enter image description here

5.under this "loop controller", create a "counter" enter image description here

6.run this thread group, and check your web app log:

There is __counter() function which is generating an incremented number each time it's being called, you can put its declaration into the URL like:

${__counter(FALSE,counter)}

and the JMeter Variable reference into the request body:

{
 "someid" : someno+${counter},
 "some world :"fixed string" + "id passed in url"
}

enter image description here

This way you will get an unique incremented number for each call

Add Counter and call the reference name you defined wherever you want.

Allows the user to create a counter that can be referenced anywhere in the Thread Group
