Setelah membuat smart home Action langkah, langkah berikutnya adalah menambahkan fungsi di fulfillment Anda untuk memproses intent smart home dan menampilkan respons yang Google Assistant recognizes.
Mengidentifikasi pengguna
Assistant membuat permintaan ke fulfillment smart home Anda
pada Tindakan dengan token akses yang disediakan
oleh server OAuth 2.0 Anda di header Authorization.
POST /fulfillment HTTP/1.1 Host: smarthome.example.com Content-Type: application/json Authorization: Bearer ACCESS_TOKEN
Sebelum merespons permintaan apa pun, logika fulfillment Anda harus memverifikasi bahwa
kredensial token ini valid dan menentukan akun pengguna terkait. Jika
token akses tidak valid, fulfillment Anda akan menampilkan
error 401 Unauthorized HTTP.
Mencantumkan perangkat dan kemampuannya
Assistant mengirimkan intent
action.devices.SYNC ke
fulfillment Anda untuk meminta daftar perangkat yang terkait dengan pengguna tertentu dan
kemampuannya. fulfillment Anda harus menampilkan ID unik untuk setiap pengguna di
kolom agentUserId dalam respons SYNC. ID ini harus berupa nilai yang tidak dapat diubah untuk mewakili pengguna ke layanan cloud Anda. Sebaiknya jangan berikan alamat email atau atribut lainnya berdasarkan setelan yang dapat diubah pengguna.
Kolom devices respons SYNC Anda berisi semua perangkat yang telah diberi otorisasi oleh pengguna
Assistant untuk diakses, jenis dan fitur yang didukungnya, dan atribut yang diperlukan untuk mengonfigurasi perilaku fitur untuk
perangkat tertentu tersebut.
Intent SYNC dipicu selama penautan akun atau saat pengguna
menyinkronkan ulang perangkat secara manual. Jika daftar perangkat, fitur yang didukung, atau nilai atribut pengguna berubah, gunakan
Request Sync untuk memicu intent
SYNC baru dan melaporkan update ke Google.
