Documentation

Overview

Package fcm provides access to the Firebase Cloud Messaging API.

For product documentation, see: https://firebase.google.com/docs/cloud-messaging

Library status

These client libraries are officially supported by Google. However, this library is considered complete and is in maintenance mode. This means that we will address critical bugs and security issues but will not add any new features.

When possible, we recommend using our newer [Cloud Client Libraries for Go](https://pkg.go.dev/cloud.google.com/go) that are still actively being worked and iterated on.

Creating a client

Usage example: 

import "google.golang.org/api/fcm/v1"
...
ctx := context.Background()
fcmService, err := fcm.NewService(ctx)

In this example, Google Application Default Credentials are used for authentication. For information on how to create and obtain Application Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.

Other authentication options

By default, all available scopes (see "Constants") are used to authenticate. To restrict scopes, use google.golang.org/api/option.WithScopes: 

fcmService, err := fcm.NewService(ctx, option.WithScopes(fcm.FirebaseMessagingScope))

To use an API key for authentication (note: some APIs do not support API keys), use google.golang.org/api/option.WithAPIKey: 

fcmService, err := fcm.NewService(ctx, option.WithAPIKey("AIza..."))

To use an OAuth token (e.g., a user token obtained via a three-legged OAuth flow, use google.golang.org/api/option.WithTokenSource: 

config := &oauth2.Config{...}
// ...
token, err := config.Exchange(ctx, ...)
fcmService, err := fcm.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))

See google.golang.org/api/option.ClientOption for details on options.

Types

type AndroidConfig 

type AndroidConfig struct {
	// CollapseKey: An identifier of a group of messages that can be collapsed, so
	// that only the last message gets sent when delivery can be resumed. A maximum
	// of 4 different collapse keys is allowed at any given time.
	CollapseKey string `json:"collapseKey,omitempty"`
	// Data: Arbitrary key/value payload. If present, it will override
	// google.firebase.fcm.v1.Message.data.
	Data map[string]string `json:"data,omitempty"`
	// DirectBootOk: If set to true, messages will be allowed to be delivered to
	// the app while the device is in direct boot mode. See Support Direct Boot
	// mode (https://developer.android.com/training/articles/direct-boot).
	DirectBootOk bool `json:"directBootOk,omitempty"`
	// FcmOptions: Options for features provided by the FCM SDK for Android.
	FcmOptions *AndroidFcmOptions `json:"fcmOptions,omitempty"`
	// Notification: Notification to send to android devices.
	Notification *AndroidNotification `json:"notification,omitempty"`
	// Priority: Message priority. Can take "normal" and "high" values. For more
	// information, see Setting the priority of a message (https://goo.gl/GjONJv).
	//
	// Possible values:
	//   "NORMAL" - Default priority for data messages. Normal priority messages
	// won't open network connections on a sleeping device, and their delivery may
	// be delayed to conserve the battery. For less time-sensitive messages, such
	// as notifications of new email or other data to sync, choose normal delivery
	// priority.
	//   "HIGH" - Default priority for notification messages. FCM attempts to
	// deliver high priority messages immediately, allowing the FCM service to wake
	// a sleeping device when possible and open a network connection to your app
	// server. Apps with instant messaging, chat, or voice call alerts, for
	// example, generally need to open a network connection and make sure FCM
	// delivers the message to the device without delay. Set high priority if the
	// message is time-critical and requires the user's immediate interaction, but
	// beware that setting your messages to high priority contributes more to
	// battery drain compared with normal priority messages.
	Priority string `json:"priority,omitempty"`
	// RestrictedPackageName: Package name of the application where the
	// registration token must match in order to receive the message.
	RestrictedPackageName string `json:"restrictedPackageName,omitempty"`
	// Ttl: How long (in seconds) the message should be kept in FCM storage if the
	// device is offline. The maximum time to live supported is 4 weeks, and the
	// default value is 4 weeks if not set. Set it to 0 if want to send the message
	// immediately. In JSON format, the Duration type is encoded as a string rather
	// than an object, where the string ends in the suffix "s" (indicating seconds)
	// and is preceded by the number of seconds, with nanoseconds expressed as
	// fractional seconds. For example, 3 seconds with 0 nanoseconds should be
	// encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should be
	// expressed in JSON format as "3.000000001s". The ttl will be rounded down to
	// the nearest second.

	NotificationCount int64 `json:"notificationCount,omitempty"`
	// NotificationPriority: Set the relative priority for this notification.
	// Priority is an indication of how much of the user's attention should be
	// consumed by this notification. Low-priority notifications may be hidden from
	// the user in certain situations, while the user might be interrupted for a
	// higher-priority notification. The effect of setting the same priorities may
	// differ slightly on different platforms. Note this priority differs from
	// `AndroidMessagePriority`. This priority is processed by the client after the
	// message has been delivered, whereas AndroidMessagePriority
	// (https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages#androidmessagepriority)
	// is an FCM concept that controls when the message is delivered.
	//
	// Possible values:

	// is set to `PRIORITY_DEFAULT`.
	//   "PRIORITY_MIN" - Lowest notification priority. Notifications with this
	// `PRIORITY_MIN` might not be shown to the user except under special
	// circumstances, such as detailed notification logs.
	//   "PRIORITY_LOW" - Lower notification priority. The UI may choose to show
	// the notifications smaller, or at a different position in the list, compared
	// with notifications with `PRIORITY_DEFAULT`.
	//   "PRIORITY_DEFAULT" - Default notification priority. If the application
	// does not prioritize its own notifications, use this value for all
	// notifications.
	//   "PRIORITY_HIGH" - Higher notification priority. Use this for more
	// important notifications or alerts. The UI may choose to show these
	// notifications larger, or at a different position in the notification lists,
	// compared with notifications with `PRIORITY_DEFAULT`.
	//   "PRIORITY_MAX" - Highest notification priority. Use this for the
	// application's most important items that require the user's prompt attention
	// or input.
	NotificationPriority string `json:"notificationPriority,omitempty"`
	// Proxy: Setting to control when a notification may be proxied.
	//
	// Possible values:
	//   "PROXY_UNSPECIFIED" - If unspecified, default to
	// `Proxy.IF_PRIORITY_LOWERED`.
	//   "ALLOW" - Try to proxy this notification.
	//   "DENY" - Do not proxy this notification.
	//   "IF_PRIORITY_LOWERED" - Only try to proxy this notification if its
	// `AndroidMessagePriority` was lowered from `HIGH` to `NORMAL` on the device.
	Proxy string `json:"proxy,omitempty"`
	// Sound: The sound to play when the device receives the notification. Supports
	// "default" or the filename of a sound resource bundled in the app. Sound
	// files must reside in /res/raw/.
	Sound string `json:"sound,omitempty"`
	// Sticky: When set to false or unset, the notification is automatically
	// dismissed when the user clicks it in the panel. When set to true, the
	// notification persists even when the user clicks it.
	Sticky bool `json:"sticky,omitempty"`
	// Tag: Identifier used to replace existing notifications in the notification
	// drawer. If not specified, each request creates a new notification. If
	// specified and a notification with the same tag is already being shown, the
	// new notification replaces the existing one in the notification drawer.
	Tag string `json:"tag,omitempty"`
	// Ticker: Sets the "ticker" text, which is sent to accessibility services.
	// Prior to API level 21 (`Lollipop`), sets the text that is displayed in the

	Ticker string `json:"ticker,omitempty"`
	// Title: The notification's title. If present, it will override
	// google.firebase.fcm.v1.Notification.title.
	Title string `json:"title,omitempty"`
	// TitleLocArgs: Variable string values to be used in place of the format
	// specifiers in title_loc_key to use to localize the title text to the user's

	// wait before turning the vibrator on. The next value indicates the `Duration`
	// to keep the vibrator on. Subsequent values alternate between `Duration` to
	// turn the vibrator off and to turn the vibrator on. If `vibrate_timings` is
	// set and `default_vibrate_timings` is set to `true`, the default value is
	// used instead of the user-specified `vibrate_timings`.
	VibrateTimings []string `json:"vibrateTimings,omitempty"`
	// Visibility: Set the Notification.visibility

Color: Represents a color in the RGBA color space. This representation is designed for simplicity of conversion to and from color representations in various languages over compactness. For example, the fields of this representation can be trivially provided to the constructor of `java.awt.Color` in Java; it can also be trivially provided to UIColor's `+colorWithRed:green:blue:alpha` method in iOS; and, with just a little work, it can be easily formatted into a CSS `rgba()` string in JavaScript. This reference page doesn't have information about the absolute color space that should be used to interpret the RGB value—for example, sRGB, Adobe RGB, DCI-P3, and BT.2020. By default, applications should assume the sRGB color space. When color equality needs to be decided, implementations, unless documented otherwise, treat two colors as equal if all their red, green, blue, and alpha values each differ by at most `1e-5`.
