Using the `Add Message API` with `TEXT_AND_NOTIFY`, a message is added to the pass's details and a push notification is sent. Tapping the notification leads users to a message view. Alternatively, updating specific fields like event name or seat using `UPDATE` or `PATCH` APIs and setting `notifyPreference` to `notifyOnUpdate` can trigger similar push notifications. A maximum of three notifications can be sent per 24 hours.\n"],null,["# Trigger Push Notifications\n\nPartner Triggered Notifications\n-------------------------------\n\n### Add Message and Notify\n\n#### Background\n\nAfter a user adds a pass you may want to send them a message related to the\npass and ensure they are notified about it. Using the [Add Message API](/wallet/tickets/events/rest/v1/eventticketclass/addmessage)\nrequest with a `message_type` equal to\n**`TEXT_AND_NOTIFY`** the following occurs:\n\n1. A \"[Message](https://developers.google.com/wallet/reference/rest/v1/Message)\" item is added to the \"back of pass\" (aka [Details\n Template](/wallet/tickets/events/resources/template#details-template)) and a push notification is sent to users with the pass saved.\n2. Once the user taps the notification it opens Google Wallet to the front of the pass (a.k.a. Card view) and the user will see a callout at the top of the screen with a \"View Message\" button.\n3. Clicking the callout will take users to the back of the pass, where new unread messages are highlighted.\n\n#### Some considerations when sending messages with notifications to users\n\n- Users must have notifications enabled for their passes to receive the push notifications related to messages.\n- Messages may contain URIs to your website or app. Hyperlinks must be a website or app related to the pass. It is a violation of the [Acceptable Use Policy](https://payments.developers.google.com/terms/aup) to send users to links not related to the pass.\n- You may send a maximum of 3 messages that trigger a push notification in a 24 hour period. Google may throttle your push notification delivery quota if it deems you are spamming your users.\n- The push notification users see on their lock screen is controlled by Google Wallet.\n- You can use the [UPDATE](/wallet/tickets/events/rest/v1/eventticketclass/update) or [PATCH](/wallet/tickets/events/rest/v1/eventticketclass/patch) methods to edit or remove message data using the regular class or object endpoint.\n\n#### Integration Steps\n\nWhen you want to notify users about a new issuer message added using the\nAddMessage API, you will need to update the [AddMessageRequest](https://developers.google.com/wallet/reference/rest/v1/AddMessageRequest)\nso that the [Message](https://developers.google.com/wallet/reference/rest/v1/Message)\nwhich contains your new text has the [MessageType](https://developers.google.com/wallet/reference/rest/v1/Message#MessageType)\n**TEXT_AND_NOTIFY** instead of **TEXT**.\n\n#### Example JSON Request to add message and notify in a Passes Class\n\n```carbon\n ...\n \"id\": ISSUER_ID.CLASS_ID\",\n \"message\":\n {\n \"header\":\"My Class message header\",\n \"body\": \"My Class message body with a \u003ca href=\"https://wallet.google\"\u003eHyperlink\u003c\\a\u003e\",\n \"id\": \"message_id\",\n \"message_type\": \"TEXT_AND_NOTIFY\"\n },\n ...\n```\n\n#### Example JSON Request to add message and notify in a Passes Object\n\n```carbon\n ...\n \"id\": OBJECT_ID\",\n \"classId\": \"ISSUER_ID.CLASS_ID\",\n \"message\":\n {\n \"header\":\"My Object message header\",\n \"body\": \"My Object message body with a \u003ca href=\"http://play.google.com/store/apps/details?id=com.google.android.apps.maps\"\u003eHyperlink\u003c\\a\u003e\",\n \"id\": \"message_id\",\n \"message_type\": \"TEXT_AND_NOTIFY\"\n },\n ...\n```\n\n#### Example [Response](/wallet/tickets/events/rest/v1/eventticketclass/addmessage#response-body) to add message and notify for a Pass Class\n\n```scilab\n // The updated resource\n …\n {\n \"kind\": \"walletobjects#walletObjectMessage\",\n \"header\": \"My Object message header\",\n \"body\": \"My Object message body with a \u003ca href=\"http://play.google.com/store/apps/details?id=com.google.android.apps.maps\"\u003eHyperlink\u003c\\a\u003e\",\n \"id\": \"message_id\",\n \"messageType\": \"textAndNotify\"\n },\n …\n```\n\n#### Exception handling\n\nAny attempts to notify more than 3 times will yield a\n**QuotaExceededException** response. Any further updates to the\npass can be set using \"**TEXT** \" instead of\n\"**TEXT_AND_NOTIFY** \" as discussed in the [Integration\nSteps](#add-message-and-notify-integration-steps).\n\n### Update Field and Notify\n\n#### Background\n\nAfter a user adds a pass you may want to trigger a push notification when you update certain\nfields. The notification will appear on the user's lock screen and inform them that there is\nan update on their pass. This notification will only trigger for a specific subset of fields\ndefined [below](#update-field-and-notify-supported-fields) using the UPDATE and PATCH\nAPI methods. Once an API call to update the pass is made the following occurs:\n\n1. A push notification is triggered and displayed on the user's lock screen, informing them of a pass update.\n2. Once the user taps the notification it opens Google Wallet to the front of the pass (a.k.a. Card view) and the user will see a callout at the top of the screen with a \"Review update\" button.\n3. Clicking the button brings the user to a screen where they can see the fields that were changed by the update.\n\n#### Some considerations when sending field update notifications\n\n- Users must have notifications enabled for their passes to receive the push notifications related to updates.\n- You may send a maximum of 3 updates that trigger a push notification in a 24 hour period. Google may throttle your push notification delivery quota if it deems you are spamming your users.\n- The push notification that users see on their lock screen is controlled by Google Wallet.\n- The `notifyPreference` field is a transient field that only lives on this request. For future requests when you wish to trigger a notification, you will have to reset this field on the class or object request.\n\n#### Integration Steps\n\nIn order to trigger these notifications, you will need to use the [existing UPDATE or PATCH\ncalls](/wallet/tickets/events/use-cases/updates#use_the_google_wallet_api) and specify the notifyPreference. When updating a field on a class or object, you can\nadd a new field, `notifyPreference`, to the class or object request to trigger the\nnotification.\n\n#### Example JSON Request to update and notify in a Class\n\n```text\n …\n \"dateTime\":\n {\n \"kind\": \"walletobjects#eventDateTime\",\n \"doorsOpen\": \"2024-09-23T19:20:50.00\"\n },\n \"multipleDevicesAndHoldersAllowedStatus\": \"multipleHolders\",\n \"notifyPreference\": \"notifyOnUpdate\",\n …\n \n```\n\nSetting the `notifyPreference` to `notifyOnUpdate` will trigger a notification, provided the updated field is currently supported.\n\n#### Supported fields\n\n##### [EventTicketClass](/wallet/tickets/events/rest/v1/eventticketclass#resource:-eventticketclass)\n\n- eventName\n- eventVenue.name\n- eventvenue.address\n- eventDateTime.doorsOpen\n- eventDateTime.start\n\n##### [EventTicketObject](/wallet/tickets/events/rest/v1/eventticketobject)\n\n- eventSeat.seat\n- eventSeat.row\n- eventSeat.section\n- eventSeat.gate\n\nAutomatic Notifications Triggered by Google Wallet\n--------------------------------------------------\n\n### Upcoming Notification\n\n\nGoogle Wallet sends a notification to the user three hours prior to the\nevent. The event time is defined by\n`class.dateTime.start`.\n\n\nTo receive this notification, the user must have notifications enabled. To check this, they can\nnavigate to **Settings \\\u003e Notifications** and see if **Updates about your passes** is\nturned on.\n\n\nThe notification shows up in the notifications area, and in the lock screen, if the user has\n[notifications enabled for the lock screen](https://support.google.com/android/answer/9079661).\n\n\nThe notification has the following unmodifiable format: \n\n```\n `class.eventName`\n \n```\n\nIf they tap the notification and unlock their device, their pass appears in the Google Wallet app.\n\n\nIf the user has multiple passes, only the soonest useable pass is shown. If they've added grouped\npasses as per [Group multiple Event tickets](/wallet/tickets/events/use-cases/group-multiple), the notification only shows one of the passes in\nthe group. However, when they tap it, the user can swipe left and right to see the other passes in\nthat group.\n\n\nThe notification is pinned and won't auto-dismiss after a user opens it. Auto-dismiss occurs 60\nminutes after `class.dateTime.start`."]]
