# Pré-visualizar Link de Chamada

> Consulta os metadados de um link de chamada sem entrar na chamada

**Auth:** `TokenAccount` ou `TokenInstance` • **Rate-limit:** `Global` (100/min) • **Idempotente:** sim

## Descrição

Consulta os **metadados de um link de chamada** sem entrar na chamada. Útil para mostrar, antes de participar, quem criou o link e se é necessária aprovação para entrar. Aceita tanto o token isolado quanto a URL completa do link no campo `link`.

## Exemplos

### Pré-visualizar por URL completa

<CodeGroup>
  ```bash cURL theme={null}
  curl -X POST "https://ryzeapi.cloud/api/call/link/$Instance_Name/preview" \
    -H "token: $Token_Instance" \
    -H "Content-Type: application/json" \
    -d '{
      "link": "https://call.whatsapp.com/audio/AbCdEfGhIjKlMnOp"
    }'
  ```

  ```javascript JavaScript theme={null}
  await fetch(`https://ryzeapi.cloud/api/call/link/${process.env.Instance_Name}/preview`, {
    method: "POST",
    headers: {
      "token":        process.env.Token_Instance,
      "Content-Type": "application/json"
    },
    body: JSON.stringify({
      link: "https://call.whatsapp.com/audio/AbCdEfGhIjKlMnOp"
    })
  });
  ```

  ```python Python theme={null}
  import os, requests

  requests.post(
      f"https://ryzeapi.cloud/api/call/link/{os.environ['Instance_Name']}/preview",
      headers={
          "token":        os.environ["Token_Instance"],
          "Content-Type": "application/json"
      },
      json={
          "link": "https://call.whatsapp.com/audio/AbCdEfGhIjKlMnOp"
      }
  )
  ```

  ```go Go theme={null}
  package main

  import (
      "net/http"
      "os"
      "strings"
  )

  func main() {
      body := strings.NewReader(`{
          "link": "https://call.whatsapp.com/audio/AbCdEfGhIjKlMnOp"
      }`)
      req, _ := http.NewRequest("POST", "https://ryzeapi.cloud/api/call/link/"+os.Getenv("Instance_Name")+"/preview", body)
      req.Header.Set("token", os.Getenv("Token_Instance"))
      req.Header.Set("Content-Type", "application/json")
      http.DefaultClient.Do(req)
  }
  ```
</CodeGroup>

### Pré-visualizar apenas pelo token

O campo `link` também aceita o token isolado, sem o restante da URL.

<CodeGroup>
  ```bash cURL theme={null}
  curl -X POST "https://ryzeapi.cloud/api/call/link/$Instance_Name/preview" \
    -H "token: $Token_Instance" \
    -H "Content-Type: application/json" \
    -d '{
      "link": "AbCdEfGhIjKlMnOp"
    }'
  ```

  ```javascript JavaScript theme={null}
  await fetch(`https://ryzeapi.cloud/api/call/link/${process.env.Instance_Name}/preview`, {
    method: "POST",
    headers: {
      "token":        process.env.Token_Instance,
      "Content-Type": "application/json"
    },
    body: JSON.stringify({
      link: "AbCdEfGhIjKlMnOp"
    })
  });
  ```

  ```python Python theme={null}
  import os, requests

  requests.post(
      f"https://ryzeapi.cloud/api/call/link/{os.environ['Instance_Name']}/preview",
      headers={
          "token":        os.environ["Token_Instance"],
          "Content-Type": "application/json"
      },
      json={
          "link": "AbCdEfGhIjKlMnOp"
      }
  )
  ```

  ```go Go theme={null}
  package main

  import (
      "net/http"
      "os"
      "strings"
  )

  func main() {
      body := strings.NewReader(`{
          "link": "AbCdEfGhIjKlMnOp"
      }`)
      req, _ := http.NewRequest("POST", "https://ryzeapi.cloud/api/call/link/"+os.Getenv("Instance_Name")+"/preview", body)
      req.Header.Set("token", os.Getenv("Token_Instance"))
      req.Header.Set("Content-Type", "application/json")
      http.DefaultClient.Do(req)
  }
  ```
</CodeGroup>

## Resposta de sucesso

```json 200 OK theme={null}
{
  "success":            true,
  "token":              "AbCdEfGhIjKlMnOp",
  "video":              false,
  "approvalRequired":   false,
  "isAdmin":            false,
  "creator":            "5511999999999@s.whatsapp.net",
  "creatorPhoneNumber": "5511999999999"
}
```

<Note>
  `approvalRequired` indica se o link tem sala de espera (participantes precisam ser aprovados antes de entrar). `isAdmin` indica se esta conta é administradora do link. `creator` e `creatorPhoneNumber` identificam quem criou o link. Esta consulta não entra na chamada nem altera o link.
</Note>
