वेब एपीआई का इस्तेमाल शुरू करना

वेब एपीआई का इस्तेमाल शुरू करने से पहले, ज़रूरी शर्तें पूरी करना न भूलें. Web API का इस्तेमाल जारी रखने के लिए, आपके पास सेवा खाता और सेवा खाता कुंजी होनी चाहिए. साथ ही, आपको Google Wallet API को कॉल करने के लिए, अपने सेवा खाते को ऐक्सेस देना होगा.

नीचे दिए गए चरणों में बताए गए कोड स्निपेट चलाने के लिए, GitHub पर सैंपल कोड डाउनलोड करें.

पुष्टि करना और अनुमति देना

Google Wallet API के लिए किए जाने वाले अनुरोधों की पुष्टि करना ज़रूरी है, ताकि Google Wallet API यह पहचान सके कि आपका ऐप्लिकेशन अनुरोध कर रहा है. ऐक्सेस टोकन पाने के लिए, सेवा खाता कुंजी का इस्तेमाल किया जाता है.

सबसे पहले, ज़रूरी लाइब्रेरी इंपोर्ट करें और सेवा खाते के JSON के लिए कुछ वैरिएबल तय करें. साथ ही, जारी करने वाले, क्लास, यूनीक उपयोगकर्ता, और उस ऑब्जेक्ट के लिए आईडी तय करें जिसे सेव किया जाएगा.

पास ऑब्जेक्ट बनाना

को फ़ॉलो करें

पास ऑब्जेक्ट को पास क्लास कहते हैं. पास ऑब्जेक्ट बनाने के लिए, आपको ये एट्रिब्यूट देने होंगे:

classId: पास की क्लास का आईडी
id: आपके ग्राहक के लिए एक खास लॉयल्टी सदस्यता आईडी
state: नया पास बनाने के लिए active.

हमारा यह भी सुझाव है कि आप यहां दिए गए एट्रिब्यूट शामिल करें:

accountId
accountName

लॉयल्टी फ़ीड में इन एट्रिब्यूट को दिखाने का तरीका जानने के लिए, टेंप्लेट से जुड़े दिशा-निर्देश देखें.

काम पूरा होने पर, आपके ग्राहक का ऑब्जेक्ट सर्वर पर बन जाता है. हालांकि, पास के ऑब्जेक्ट को Google उपयोगकर्ता या उनके डिवाइस से लिंक नहीं किया जाता है. किसी पास की जानकारी, Google Wallet उपयोगकर्ता से जोड़ने के लिए, पहले उपयोगकर्ता को Google Wallet में पास जोड़ना होगा.

Google Wallet में जोड़ा जा रहा है

Google Wallet में पास की जानकारी जोड़ने पर, पास की जानकारी Google उपयोगकर्ता से जुड़ जाती है. यह पास, सिर्फ़ लॉग इन की गई Google पहचान की जानकारी के तौर पर शुरू किया जा सकता है. उपयोगकर्ता को 'Google वॉलेट में जोड़ें' यूआरएल पर भेजने के लिए, ऐसा किया जा सकता है.

'Google Wallet में जोड़ें' यूआरएल, डाइनैमिक तौर पर जनरेट किया गया यूआरएल होता है. इसमें, पिछले चरण में बनाए गए पास ऑब्जेक्ट आईडी के बारे में जानकारी मौजूद होती है. यह जानकारी JSON वेब टोकन (JWT) के तौर पर कोड में बदली जाती है.

JSON वेब टोकन (JWT)

JWT में दावा किया गया है कि आपने पास (जारी करने वाला) ऐसे पास ऑब्जेक्ट के बारे में दावे कर रहे हैं जिन्हें उपयोगकर्ता सेव करेगा. JWT में सेवा खाता बनाएं चरण से मिली सेवा खाता कुंजी के private_key का इस्तेमाल करके, हस्ताक्षर करना होगा. Google, JWT हस्ताक्षर की पुष्टि करके इन दावों की पुष्टि करता है.

JWT के दावों का स्ट्रक्चर इस तरह का होना चाहिए:

{
  "aud": "google",
  "origins": ["https://example.com"],
  "iss": "my-service-account@my-project-id.iam.gserviceaccount.com",
  "typ": "savetowallet",
  "payload": {
    "loyaltyObjects": [
      {
        "id": "PASSES_OBJECT_ID_1234567890"
      }
    ]
  }
}

हस्ताक्षर किया गया JWT मिलने के बाद, इस जानकारी का इस्तेमाल करके Google Wallet में लिंक जोड़ें.

Google Wallet लिंक में जोड़ें

'Google Wallet में जोड़ें' लिंक का फ़ॉर्मैट ऐसा होता है:

https://pay.google.com/gp/v/save/{token}

इस लिंक को आपके वेब पेज या ईमेल में हाइपरलिंक के तौर पर एम्बेड किया जा सकता है. इसे ग्राहक को चैट और मैसेज (एसएमएस) जैसे दूसरे चैनलों का इस्तेमाल करके भी भेजा जा सकता है.

सुरक्षित की गई JWT की लंबाई 1800 वर्णों की होती है. अगर आपका JWT इस सीमा से कम है, तो पूरे ऑब्जेक्ट को हस्ताक्षर किए गए JWT में शामिल किया जा सकता है. आपके JWT इस सीमा से कम ही रहने चाहिए. अगर वर्णों की संख्या 1800 से ज़्यादा है, तो वेब ब्राउज़र में काट-छांट करने के कारण हो सकता है कि 'Google वॉलेट में जोड़ें' काम न करे.

Google Wallet में जोड़ें बटन

सबसे अच्छे नतीजों के लिए, अपने वेब पेज, ईमेल या Android ऐप्लिकेशन में Google Wallet बटन की एसेट का इस्तेमाल करें.

Google Wallet बटन दो तरह से रेंडर किया जा सकता है:

वेबसाइटों के लिए JavaScript वेब बटन.
JWT लिंक, जिसमें ईमेल, एसएमएस, और ऐप्लिकेशन, और वेबसाइटों का बटन मौजूद होता है.

[केवल परीक्षण] पास

डेमो मोड में होने पर, आपके पास वाले सभी पास के शीर्षक में अतिरिक्त नाम "[TEST ONLY]" होगा. यह डेमो पास को लाइव पास से अलग करने के लिए है. हमारी टीम से प्रोडक्शन की मंज़ूरी मिलने के बाद, अगर उपयोगकर्ता किसी कनेक्ट किए गए डिवाइस पर वॉलेट ऐप्लिकेशन को दोबारा खोलता है, तो इन पास के पास अब कोई अतिरिक्त मैसेज नहीं होगा.
