Set variable with the first array item of a response

[quammy]

How can I set a variable with value of a property of an object that is the first item of a response json array?
Here is a response sample:

[
  {
    "id": 4267358,
    "is_active": true,
    "name": "App1",
    "pcn_business_experience": null
  }
]

and this is my REST Client code:

@test1 = {{companies.response.body[0].id}}           ///////// this doesn't work

### get all companies
// @name companies
GET {{BaseURL}}/rest/v1.0/companies
Content-Type: application/json

Thanks!

I've used this successfully (note the $ after the body )

@test1 = {{request1.response.body.$.results[0].id}}

Perfect, thank you!
this one worked for me:
@test1 = {{request1.response.body.$.[0].id}}

This discussion is addressed by the new @set directive, which lets you capture response values (response.headers.* / response.body.*) into shared runtime variables and reuse them across .http files.
