从Facebook Marketing API检索线索

Question

我正在尝试使用PHP中的curl从Facebook Marketing API检索Facebook页面表单的线索：

$ch = curl_init();
$user_link = https://graph.facebook.com/v2.7/'.$formDetails[0].'/leads?access_token='.$page->page_access_token;
curl_setopt($ch, CURLOPT_URL, $user_link);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$temp_output = curl_exec($ch);

我正在从这次热潮中获得潜在客户，现在的问题是我想根据https://developers.facebook.com/docs/marketing-api/guides/lead-ads/leads/v2.8中指定的时间戳进行检索这是我的基于时间戳检索潜在客户的代码

 $data = [array(
    "field" => "time_created",
    "operator" => "GREATER_THAN",
    "value" => 1476275295
)];
$data = json_encode($data);
$ch = curl_init();
$user_link = "https://graph.facebook.com/2.7/<form_id>/leads?filtering=".$data."&access_token=my access token";
curl_setopt($ch, CURLOPT_URL, $user_link);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$temp_output = curl_exec($ch);
$output = json_decode($temp_output);

我收到错误消息

{
  "error": {
    "message": "Unknown path components: /my form_id/leads",
    "type": "OAuthException",
    "code": 2500,
    "fbtrace_id": "CP5hFV3v1zN"
  }
}

使用潜在客户的/ leads检索潜在客户时，您将获得创建的日期时间时间戳，看起来像是“ created_time”：“ 2017-03-08T23：15：14 + 0000”

如果您在过滤参数中将UNIX时间戳值用于上述内容，则api将仅返回在指定时间后生成的线索。
