          }
        }
      ],
      "meta": {
        "sort": "-dateAdded",
        "page": {
          "number": 1,
          "size": 10
        }
      }
    }
  ],
  "meta": {

    }
  }
}

As you can see there´s 2 items on the “evento” structure. How to build a email token that will retrieve only the item with idwebinar equals 81021417635 ?

I keep trying some syntax alternatives but it only returns my latest item:

{custom-object=evento:linkinscricao|
where=evento:idwebinar=81021417635 | order=latest | limit=1 | default= | format=default}

Unfortunaly there´s no examples in Custom objects — Acquia Docs

@rcheesley @escopecz or @fedy can you help me?

The where condition works only for segment filters. Please take a look at Email tokens · acquia/mc-cs-plugin-custom-objects Wiki · GitHub

So in order to do what you want you need to send the email to a segment that has filter on evento:idwebinar=81021417635
