Facebook api – Facebook Conversion API – Not Received Test Server Events for app

We Start for implement Facebook Conversion Api for App events.

We Setup conversion api by manual

Not received any server event in test event tool , specially this case: "action_source": "app".

We done this steps in facebook developer

• Create Facebook app and connect it with the verified business account.
• Adding IOS/Android Platform

We done this steps in event manager

• Link App with new pixel
• Generated access token

We generated Access Token using events manager to allow setup conversion api manual
guideline for generate token

For Testing Server Events we used Graph API Explorer Example,

this is the example for data

{
  "data": [
    {
      "action_source": "app",
      "app_data": {
        "advertiser_tracking_enabled": false,
        "application_tracking_enabled": false,
        "extinfo": [
          "a2",
          "com.some.app",
          "771",
          "Version 7.7.1",
          "10.1.1",
          "OnePlus6",
          "en_US",
          "GMT-1",
          "TMobile",
          "1920",
          "1080",
          "2.00",
          "2",
          "128",
          "8",
          "USA/New York"
        ]
      },
      "event_id": 12345,
      "event_name": "TestEvent",
      "event_time": 1687346413,
      "user_data": {
        "client_ip_address": "254.254.254.254",
        "client_user_agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:63.0) Gecko/20100101 Firefox/63.0",
        "em": "f660ab912ec121d1b1e928a0bb4bc61b15f5ad44d5efdc4e1c92a25e99b8e44a"
      }
    }
  ],
  "test_event_code": "TEST68424"
}
