for example:

newJsonBody(body -> {
           body.minArrayLike("users", 2, users -> {
               users.stringType("name");
               users.integerType("age");
           });
        });

you can return this result from you method and use inside .body() with PactDslWithProvider builder

but i am asking if i dont want to give property name "users"

as it is just an array of json objects

in the example above array of arrays is used, but it can be applied for array of objects as well

As an aside, I'd recommend using objects (not arrays) as the root element in JSON responses, for extensibility. It's much easier to add new fields to an object (backwards-compatible change), than wrapping your root array in an object later (backwards-incompatible change).

(This is probably part of the reason that it's less documented)
