Customize your Firebase In-App Messaging messages

Firebase In-App Messaging provides a useful set of preconfigured behaviors and message types with a default look and feel, but in some cases you may want to extend behaviors and message content. In-App Messaging allows you to add actions to messages and customize message look and feel.

Add an action to your message

With actions you can use your in-app messages to direct users to a website or a specific screen in your app.

Firebase In-App Messaging uses link handlers to process actions. The SDK is able to use a number of handlers, so if your app already has one, Firebase In-App Messaging can use that without any further setup. If you don't yet have a handler, you can use Firebase Dynamic Links. To learn more, read Create Dynamic Links on Android.

Add the action to your message using the Firebase console

Once your app has a link handler, you're ready to compose a campaign with an action. Open the Firebase console to Messaging, and start a new campaign or edit an existing campaign. In that campaign, provide a Card, Button text and Button action, an Image action, or a Banner action, where the action is a relevant deep link.

The action's format depends on which message layout you choose. Modals get action buttons with customizable button text content, text color, and background color. Images and top banners, on the other hand, become interactive and invoke the specified action when tapped.

Modify message look and feel

Use the Firebase In-App Messaging display SDK for Android to customize how In-App Messaging displays your messages, available now on the Firebase GitHub repo.

Creating your own display is a two step process:

  1. Write your own implementation of the FirebaseInAppMessagingDisplay class.
  2. Register that implementation with the headless Firebase In-App Messaging SDK.
