Sampel Java: pengiriman aplikasi dengan opsi game dan trailer

Artikel ini menyediakan contoh kode Java yang menunjukkan cara menggunakan API pengiriman Microsoft Store untuk tugas-tugas ini:

  • Dapatkan token akses Azure AD untuk digunakan dengan API pengiriman Microsoft Store.
  • Membuat pengiriman aplikasi
  • Konfigurasikan data listingan Store untuk pengiriman aplikasi, termasuk opsi daftar lanjutan game dan trailer .
  • Unggah file ZIP yang berisi paket, mencantumkan gambar, dan file trailer untuk pengiriman aplikasi.
  • Terapkan pengiriman aplikasi.

Membuat pengiriman aplikasi
