The media object

FieldTypeRequiredDescription
media.urlstringYesHTTPS URL to the asset (max 2048 chars). HTTP is rejected.
media.typestringYesOne of image, video, or audio.
ℹ Thông tin

The request takes a nested media object, but the server flattens it on the way back out — responses return media_url and media_type as top-level fields rather than a nested object.

⚠ Cảnh báo

Apple enforces strict size caps on notification attachments — image 10 MB, audio 5 MB, video 50 MB. Larger files are silently dropped by the iOS notification service extension and the notification falls back to a plain alert with no media.

Image

JPEG, PNG, GIF, and HEIC are supported. iOS shows the image inline on the lock screen and in the expanded notification.

      "url": "https://example.com/snapshots/doorbell.jpg",
      "type": "image"
    },
    "push": true
  }'

Video

MP4 (H.264) is the most reliable format. iOS shows a play button on the inline preview and plays the clip when the user expands the notification.

      "url": "https://example.com/clips/motion.mp4",
      "type": "video"
    },
    "push": true
  }'

Audio

MP3, WAV, and M4A are supported. The expanded notification shows audio playback controls directly.

Đính kèm âm thanh

      "type": "audio"
    },
    "push": true
  }'
💡 Mẹo

Host media on a CDN with cache headers — iOS downloads the attachment on every device that receives the push, and slow downloads can cause the notification to fall back to a plain alert before the asset arrives.
