    • API: API yang dapat Anda panggil untuk melakukan aksi tersebut.

    • Access level: Tingkat akses yang telah ditentukan untuk setiap API. Nilai yang valid: create, list, get, update, dan delete.

    • Resource type: Jenis resource yang mendukung otorisasi untuk melakukan aksi tersebut. Ini menunjukkan apakah aksi tersebut mendukung izin tingkat resource. Resource yang ditentukan harus kompatibel dengan aksi tersebut. Jika tidak, kebijakan tersebut tidak akan berlaku.

      • Untuk API dengan izin tingkat resource, jenis resource yang diperlukan ditandai dengan tanda bintang (*). Tentukan Nama Sumber Daya Alibaba Cloud (ARN) yang sesuai dalam elemen Resource pada kebijakan.

      • Untuk API tanpa izin tingkat resource, ditampilkan sebagai All Resources. Gunakan tanda bintang (*) dalam elemen Resource pada kebijakan.
