JSON वेब टोकन, आम तौर पर इस्तेमाल किए जाने वाले इंडस्ट्री स्टैंडर्ड हैं. इनकी मदद से, जानकारी को JSON ऑब्जेक्ट के तौर पर सुरक्षित तरीके से ट्रांसफ़र किया जा सकता है. Google Wallet API का इस्तेमाल करते समय, आपको उस पास ऑब्जेक्ट की जानकारी को कोड में बदलना होता है जिसका इस्तेमाल आपको JWT (इसे "जोट") फ़ॉर्मैट में पास इंस्टेंस बनाने के लिए करना है. इसके बाद, उस JWT को Google Wallet API को अनुरोध करके भेजें.
JWT को Google Wallet API पर भेजे जाने से पहले, एक शेयर किए गए सीक्रेट के साथ साइन करके सुरक्षित रखा जाता है. अगर Google Wallet REST API का इस्तेमाल किया जा रहा है, तो साइन करने का सीक्रेट, आपकी Google Cloud सेवा खाता कुंजी है. अगर Google Wallet के Android SDK टूल का इस्तेमाल किया जा रहा है, तो आपके Android ऐप्लिकेशन के लिए SHA-1 फ़िंगरप्रिंट, साइनिंग सीक्रेट होता है.
JWT में पास एन्कोड करना
जब LoyaltyObject बन जाए, तो इसे payload.LoyaltyObjects एट्रिब्यूट के साथ, साइन नहीं किए गए JWT के साथ रैप करें, जैसा कि इस स्निपेट में दिखाया गया है:
JSON
{
"iss": "OWNER_EMAIL_ADDRESS",
"aud": "google",
"typ": "savetowallet",
"iat": "UNIX_TIME",
"origins": [],
"payload": {
"loyaltyObjects": [ NEW_OBJECT ]
}
}JWT के सही फ़ॉर्मैट के बारे में ज़्यादा जानने के लिए, JWT रेफ़रंस देखें.
JWT पर हस्ताक्षर करें
JWT को Google Wallet API पर भेजे जाने से पहले, एक शेयर किए गए सीक्रेट के साथ साइन करके सुरक्षित रखा जाता है. अगर Google Wallet REST API का इस्तेमाल किया जा रहा है, तो साइन करने का सीक्रेट, आपकी Google Cloud सेवा खाता कुंजी है. अगर Google Wallet के Android SDK टूल का इस्तेमाल किया जा रहा है, तो आपके Android ऐप्लिकेशन के लिए SHA-1 फ़िंगरप्रिंट, साइनिंग सीक्रेट होता है.
वेब, ईमेल, और एसएमएस
JWT को Google Wallet Business Console में अनुमति दिए गए Google Cloud सेवा खाते से जुड़ी सेवा खाते की कुंजी का इस्तेमाल करके साइन करना होगा. Google Wallet API, JWT हस्ताक्षर की पुष्टि करके इन दावों की पुष्टि करेगा.
JWT पर हस्ताक्षर करने से एक टोकन बनेगा, जिसका इस्तेमाल 'Google Wallet में जोड़ें' लिंक बनाने के लिए किया जा सकता है. इसका इस्तेमाल उपयोगकर्ता को पास जारी करने के लिए किया जा सकता है:
