Bevor du die Web API verwendest, müssen die Voraussetzungen erfüllt sein. Du benötigst ein Dienstkonto und einen Dienstkontoschlüssel, um mit der Web API fortfahren zu können. Außerdem musst du Zugriff auf dein Dienstkonto gewähren, um die Google Wallet API aufzurufen.
Lade den Beispielcode von GitHub herunter, um die Code-Snippets auszuführen, auf die in den folgenden Schritten verwiesen wird.
Authentifizierung und Autorisierung
Anfragen an die Google Wallet API müssen authentifiziert werden, damit die Wallet API erkennen kann, dass die Anfrage von deiner Anwendung stammt. Dazu wird mit dem Dienstkontoschlüssel ein Zugriffstoken abgerufen.
Führe zuerst die erforderlichen Bibliotheksimporte durch und definiere einige Variablen für die JSON-Datei des Dienstkontos sowie IDs für den Aussteller, die Klasse, den einzelnen Nutzer und das Objekt, das gespeichert werden soll.

Karten-/Ticketobjekt erstellen
Ein Karten-/Ticketobjekt ist eine Instanz einer Karten-/Ticketklasse. Zum Erstellen eines Karten-/Ticketobjekts musst du die folgenden Attribute angeben:
classId: Dieidder Karten-/Ticketklasseid: Eine eindeutige ID für deinen Kunden
Weitere Informationen zur Darstellung dieser Attribute auf generischen Karten/Tickets findest du in den Vorlagenrichtlinien.

Sobald der Vorgang abgeschlossen ist, wird das Karten-/Ticketobjekt des Kunden auf dem Server erstellt. Allerdings ist das Karten-/Ticketobjekt dann noch nicht mit einem Google-Nutzer oder dessen Gerät verknüpft. Damit die Karte oder das Ticket einem Google Wallet-Nutzer zugeordnet werden kann, muss der Nutzer zuerst die Karte oder das Ticket in Google Wallet speichern.
Zu Google Wallet hinzufügen
Durch das Hinzufügen einer Karte oder eines Tickets zu Google Wallet wird das Karten-/Ticketobjekt mit einem Google-Nutzer verknüpft und kann nur im Kontext einer angemeldeten Google-Identität initiiert werden. Dazu muss der Nutzer zu einer „Zu Google Wallet hinzufügen“-URL geleitet werden.
Die „Zu Google Wallet hinzufügen“-URL ist eine dynamisch generierte URL, die die folgenden Informationen über die im vorherigen Schritt erstellte ID des Karten-/Ticketobjekts enthält. Diese Informationen sind als JSON-Webtoken (JWT) codiert.
JSON-Webtoken (JWT)
Das JWT enthält Anforderungen, die du (der Aussteller) bezüglich des Karten-/Ticketobjekts stellst, das vom Nutzer gespeichert wird. Das JWT muss mit dem „private_key“ aus dem Dienstkontoschlüssel signiert werden, der im Schritt Dienstkonto erstellen abgerufen wurde. Google validiert diese Anforderungen dann durch Bestätigen der JWT-Signatur.
Die JWT-Anforderungen sollten folgende Struktur haben:
{
"aud": "google",
"origins": ["https://example.com"],
"iss": "my-service-account@my-project-id.iam.gserviceaccount.com",
"typ": "savetowallet",
"payload": {
"genericObjects": [
{
"id": "PASSES_OBJECT_ID_1234567890"
}
]
}
}
Erstelle das JWT claims (Schritt 1) und rufe das token ab. Signiere dazu die Anforderungen mit dem private_key des Dienstkontoschlüssels (Schritt 2):

Nachdem du ein signiertes JWT abgerufen hast, kannst du anhand dieser Informationen einen Link Zu Google Wallet hinzufügen erstellen.
Link „Zu Google Wallet hinzufügen“
Der Link „Zu Google Wallet hinzufügen“ hat folgendes Format:
https://pay.google.com/gp/v/save/{token}
Dieser Link kann als Hyperlink in deine Webseite oder eine E-Mail eingefügt werden. Er kann auch über andere Kanäle wie Chat und SMS an den Kunden gesendet werden.
Die sichere Länge eines codierten JWT beträgt 1.800 Zeichen. Wenn dein JWT unter diesem Grenzwert liegt, kann das gesamte Objekt in das signierte JWT aufgenommen werden. Deine JWTs sollten unter diesem Limit bleiben. Wenn dein JWT über 1.800 Zeichen lang ist, wird es vom Webbrowser abgeschnitten und kann möglicherweise nicht gespeichert werden.
Schaltfläche „Zu Google Wallet hinzufügen“
Die besten Ergebnisse erzielst du, wenn du die Google Wallet-Schaltflächen auf deiner Webseite, in deiner E-Mail oder in deiner Android-Anwendung verwendest.
Die Google Wallet-Schaltfläche kann auf zwei Arten gerendert werden:
- Die JavaScript-Webschaltfläche kann für Websites verwendet werden.
- Der JWT-Link mit einer Schaltfläche kann für E‑Mails, SMS, Apps und Websites verwendet werden.
[TEST ONLY] Karten/Tickets
Wenn du dich noch im Demomodus befindest, haben alle erstellten Karten/Tickets den zusätzlichen Text „[TEST ONLY]“ im Titel der Karte bzw. des Tickets. Damit lassen sich Demokarten/-tickets von Livekarten/-tickets unterscheiden. Sobald du die Produktionsgenehmigung von unserem Team erhalten hast, werden diese Demokarten/-tickets nicht mehr den zusätzlichen Text enthalten, wenn der Nutzer die Wallet-App auf einem verbundenen Gerät öffnet.
Nächste Schritte
- Darstellung der generischen Karten/Tickets anpassen
- Einbindung testen und online gehen
- Hast du noch Fragen? Weitere Informationen findest du in unseren FAQs.
