# Unduh konten video HappyHorse

> Unduh file MP4 yang sudah selesai untuk task video HappyHorse melalui route content.

Gunakan endpoint ini untuk mengunduh file MP4 untuk task video HappyHorse yang sudah selesai. Jika task masih berjalan, API akan mengembalikan error JSON alih-alih byte video.

## Sebelum mengunduh

* Buat task dengan [Buat video HappyHorse](./create).
* Lakukan polling dengan [Ambil video HappyHorse](./retrieve) hingga `status` bernilai `completed`.
* Berikan task ID yang sama ke endpoint ini.

## Simpan media yang sudah selesai

Body respons berisi konten biner `video/mp4`. Simpan byte tersebut ke penyimpanan Anda sendiri ketika aplikasi Anda memerlukan akses yang tahan lama ke media yang dihasilkan.
