About Alexa for Apps


Alexa for Apps lets users use voice to access content and functionality in your apps and websites.

The Alexa for Apps mobile experience lets users use voice on the Alexa app to access their iOS or Android apps and websites.

Alexa for Apps introduces the Alexa for Apps non-mobile experience, also known as "Send to Phone." This feature lets users use an Alexa-enabled device, such as an Amazon Echo, to access your mobile apps and websites.

In Alexa for Apps, a single Alexa skill can provide deep links to both iOS and Android apps. If you already have existing deep links, you can use them in your skill just as they are, without changing your app.

Alexa for Apps capabilities and limitations

Alexa for Apps lets you connect users to content or functionality in your iOS app, Android app, or website. If a user invokes your skill on an Alexa-enabled device, you can send an app link to their phone in a push notification and a card. If they do so on a mobile device, you can directly open your app or website on the device.

Alexa for Apps can deep-link to your app even if your user doesn't have the app installed yet. In that case, you can redirect them to the iOS App Store, the Google Play Store, or your website.

Amazon only supports Alexa for Apps for Alexa custom skills. You can't use Alexa for Apps with skills that use pre-built interaction models, such as Smart Home, music, or video skills.

How Alexa for Apps works

When your skill makes an Alexa for Apps request, your user has a mobile or non-mobile experience, depending on the device they're using. If they're on an Alexa-enabled mobile device or the Alexa app, Alexa launches your app on their phone and takes them to the deep-linked content. If they're on a non-mobile Alexa-enabled device, such as an Amazon Echo, Alexa sends your deep link to their phone as a push notification. When they tap the notification, the link takes them to your app or website.

Alexa for Apps mobile experience (direct launch)

When a user invokes your skill on an Alexa built-in phone or the Alexa app, your skill can use Alexa for Apps to launch your app or website directly on the user's phone. The following diagram shows the mobile request flow for a City Guide custom skill.

  1. An Alexa app user says, "Alexa, ask City Guide to search for coffee" on their iPhone or Android phone.
  2. The Alexa app sends the request to the City Guide skill. The skill checks for the presence of a directLaunch field in the AppLink object in the request payload. This field is present, indicating that the device supports the Alexa for Apps mobile experience and can directly launch your app or website on the user's phone.
  3. The City Guide skill decides to send the user to the City Guide app. The skill uses a managed skill connection request to send an iOS or Android deep link to the Alexa for Apps skill. Along with the link, it sends a mandatory topic and other custom fields. The topic is a prompt that helps the user know what the deep-link does, for example, "See search results." On an iPhone, the City Guide skill might request to send a universal link of https://www.cityguide.com/search?search_terms=coffee. For details about the connection request, see Alexa for Apps Skill Connection Request Reference.
  4. The Alexa for Apps provider skill passes the deep-link request to the Alexa app.
  5. The Alexa app uses the universal link to open the City Guide app, and then takes the user to the search results for coffee.
  6. The City Guide app displays the search results.
  7. The Alexa for Apps provider skill tells the City Guide skill whether the deep-link request is successful. If the request isn't successful, Alexa transfers control back to the City Guide skill.

Alexa for Apps non-mobile experience (Send to Phone)

When a user invokes your skill on a non-mobile Alexa-enabled device, your skill can use the Alexa for Apps Send to Phone (S2P) feature. With Send to phone, Alexa for Apps sends a link via a push notification to the user's phone. Alexa also sends a card to the user's Alexa app home page. Users receive the notification in the Alexa app on their Android or iOS phone. The following diagram shows the non-mobile request flow for a recipe skill.

  1. An Amazon Echo device user says, "Alexa, ask Recipes to search for lasagna recipes."
  2. The Echo device sends the request to the Recipes skill. The skill checks for the presence of a sendToDevice field in the context.AppLink object in the request payload. If this field is present, the device supports the Alexa for Apps non-mobile experience and can send a link to the user's phone by using a managed skill connection request. In its request to the Alexa for Apps skill, the Recipes skill sends an iOS or Android deep link, or both (if the skill has links for both). Along with each link, the skill sends a topic and any custom fields. The topic is a prompt that tells the user what the deep link does, for example, "See lasagna recipes." In this example, the user has an iPhone, and the Recipes skill sends a universal link of https://www.recipesamzn.com/search?search_terms=lasagna. For details about the connection request, see Alexa for Apps Skill Connection Request Reference.
  3. Alexa for Apps confirms the notification recipient with the user.
  4. Alexa for Apps sends the appropriate deep link to the Alexa app installed on the user's phone, both as a push notification and a home card in the Alexa app.
  5. Alexa for Apps tells the Recipes skill whether the notification was sent successfully, and transfers control back to the Recipes skill.
  6. The user sees the notification and taps it to view the search results in the Recipes app.
  7. The Recipes app displays the search results.

In Alexa for Apps, your skill uses a managed skill connection request to send a deep link to your app or website. The request contains the following pieces of information:

  • A mandatory primary deep link, which connects the user to the content or functionality they want in your mobile app or website
  • An optional deep link to handle fallback cases, such as when the user hasn't installed your app. A fallback deep link can be one of the following items:
    • A website link to fulfill the user's request even when the user hasn't installed your app
    • A uniform resource identifier (URI) to the Apple App Store or Google Play Store for the user to download your app.
  • A mandatory verb-first call-to-action topic field to indicate what the link is doing; for example, "See lasagna recipes", "Get your boarding pass", or "View your messages."

You can also include a voice prompt as part of your skill response that calls Alexa for Apps. Alexa plays this prompt before any additional Send to Phone-related text-to-speech (TTS) that Alexa plays to determine the correct recipient. An example of this prompt might be to provide initial information by voice, such as, "Your flight from Los Angeles International Airport to Madrid is on time."

Alexa for Apps supports the following types of deep links: Universal link, custom scheme, common scheme, Android custom intent, Android common intent, Android Package Manager app launch, and website link.

A universal link is an HTTP or HTTPS URL that a user can open on your mobile app when the app is available, or by a web browser, if the app isn't installed on the user's phone.

Custom scheme

A custom scheme is a link to functionality within your app. You must also provide the package name or app ID.

Common scheme

A common URI scheme is a well-known URI type that typically accomplishes functionality at a system level. The target app doesn't need to be specified. Alexa for Apps allows the following common URI schemes: "tel:<phone number>" for telephone numbers, "maps:q=<physical location>" for iOS maps, and "geo:<physical location>" for Android maps.

Android custom intent

An Android custom intent is an app-specific Android intent. You must specify the package name in the custom intent, so users can only be sent to the specified app.

Android common intent

Android common intents are a set of Android intents that an app can use to perform common actions through another app. The target app doesn't need to be specified. Alexa for Apps allows the following Android common intents: SHOW_IN_MAP, ADD_CALENDAR_EVENT, PLAY_MEDIA, START_PHONE_CALL, and OPEN_SETTINGS.

Android Package Manager app launch

Sometimes you might simply want to launch an app, for example, to open a game or a news feed. For launching Android apps, just include the package name by using the Android Package Manager.

In case your skill doesn't own a relevant app or doesn't want to launch an app, your skill can launch a website link in a browser. The web domains must adhere to Alexa content policies.

If you already have deep links enabled in your mobile app, you can use Alexa for Apps to call those existing deep links. If you're new to deep links and want to add them to your app, see the following resources:
