Mengautentikasi dengan OAuth

OAuth memungkinkan agen memverifikasi identitas pengguna dan memberikan informasi yang dipersonalisasi dalam percakapan dengan cara yang aman. Dengan meminta pengguna login ke penyedia OAuth tepercaya, agen dapat mengakses data pengguna yang dapat membantu memberikan jawaban cepat melalui otomatisasi dan menghemat waktu untuk agen langsung.

Business Messages mendukung OAuth 2.0 dengan saran permintaan Autentikasi, yang meminta pengguna untuk login ke penyedia OAuth yang Anda konfigurasikan untuk agen. Setelah pengguna berhasil login, Business Messages akan meneruskan kembali kode otorisasi ke agen sebagai pesan.

Setelah mendapatkan kode otorisasi dari penyedia OAuth, Anda dapat berintegrasi dengan API mereka dan mendukung alur percakapan yang memerlukan informasi identitas pengguna. Perlu diingat bahwa setiap layanan yang berinteraksi dengan Anda memiliki persyaratan penggunaan sendiri.

Mengonfigurasi OAuth untuk agen

Untuk mengaktifkan saran permintaan Authentication untuk agen, Anda harus mengonfigurasi OAuth terlebih dahulu.

Untuk menentukan konfigurasi OAuth, Anda membuat permintaan PATCH dengan Business Communications API untuk memperbarui kolom endpointUrl agen.

Setelah menentukan URL endpoint, Anda perlu menyimpan URI pengalihan untuk agen dan memperbarui URI pengalihan di informasi penyedia OAuth Anda.

Prasyarat

Anda memerlukan item berikut:

  • Penyedia OAuth yang mengikuti spesifikasi OAuth 2.0
  • Jalur kunci akun layanan project GCP Anda di mesin pengembangan
  • Agen name (misalnya, "brands/12345/agents/67890")

    Jika Anda tidak mengetahui name agen, lihat Mencantumkan semua agen untuk merek.

  • URL endpoint tempat pengguna login ke penyedia OAuth

Mengirim permintaan update

Untuk memperbarui agen, jalankan perintah berikut. Ganti variabel dengan nilai yang Anda identifikasi di Prasyarat.

curl -X PATCH \
"https://businesscommunications.googleapis.com/v1/brands/BRAND_ID/agents/AGENT_ID?updateMask=businessMessagesAgent.authorizationConfig" \
-H "Content-Type: application/json" \
-H "User-Agent: curl/business-communications" \
-H "$(oauth2l header --json PATH_TO_SERVICE_ACCOUNT_KEY businesscommunications)" \
-d "{
    'businessMessagesAgent': {
        'authorizationConfig': {
            'endpointUrl': 'ENDPOINT_URL',
        },
    },
}"

Mengupdate URI pengalihan

Setelah OAuth dikonfigurasi untuk agen, Anda perlu menambahkan empat URI pengalihan ke penyedia OAuth Anda:

  • https://business.google.com/callback
  • https://business.google.com/callback?
  • https://business.google.com/message?az-intent-type=1
  • https://business.google.com/message?az-intent-type=1&

Anda harus menyertakan semua URL alihan dalam informasi penyedia OAuth Anda.

Proses untuk memperbarui URI pengalihan bervariasi menurut penyedia OAuth. Lihat penyedia OAuth Anda untuk mendapatkan petunjuk.

Setelah OAuth dikonfigurasi untuk agen Anda, Anda dapat mengautentikasi pengguna dengan saran permintaan Authentication.

Mengautentikasi pengguna

Setelah mengonfigurasi OAuth untuk agen, Anda dapat meminta pengguna untuk login dengan saran permintaan Authentication.

Prasyarat

Anda memerlukan item berikut:

  • Jalur kunci akun layanan project GCP Anda di mesin pengembangan
  • Agen name (misalnya, "brands/12345/agents/67890")

    Jika Anda tidak mengetahui name agen, lihat Mencantumkan semua agen untuk merek.

  • Client ID dari penyedia OAuth Anda

  • Persyaratan verifikasi kode dari penyedia OAuth Anda

  • Cakupan dari penyedia OAuth Anda

Mengirim saran permintaan autentikasi

Saran permintaan autentikasi

Untuk mengautentikasi pengguna,

  1. Membuat pemverifikasi kode dan string verifikasi kode untuk permintaan OAuth. Hubungi penyedia OAuth Anda untuk mengetahui persyaratan dan opsi.
  2. Kirim pesan dengan saran permintaan Authentication.

  1. Saat pengguna mengetuk saran dan berhasil login, Anda menerima pesan di webhook agen Anda. Ambil kode otorisasi dari kolom authenticationResponse.code.

Setelah menerima pesan, Anda dapat menukar kode otorisasi dan pemverifikasi kode untuk token akses dari penyedia OAuth Anda. Anda dapat mengakses data pengguna dengan token akses.

Untuk contoh percakapan dengan autentikasi, termasuk contoh kode, lihat Mengautentikasi pengguna.
