Build Your Skill

Note: Sign in to the developer console to build or publish your skill.

Use the Build page in the Alexa developer console to configure your skill, specify the endpoints for your skill service, and more. For custom skills, you define the custom voice interaction model, add multi-model responses, and select the interfaces that your skill uses. For skills that use the prebuilt voice interaction model, you define account linking and permissions on the Build page.

Configuration options for your skill are available on the Build page in left pane of the developer console. Some items are required and some items are optional. The items that you see in the pane depend on the model that you selected when you created your skill.

Custom model

For skills that use the custom voice interaction model, the Build page displays a list of the minimum steps to configure your skill and get it ready to test. You must complete the required steps. For more details about custom skills, see Understand Custom Skills.

The check list shows the required steps: step 1 invocation name, step 2 intents, samples, and slots, step 3 build model, and step 4 endpoint. — Steps to build a custom skill

The following table summarizes the configuration options for a skill with the custom model. You can find the options in the left pane under CUSTOM.

Option	Description
Invocations	Define your skill invocation name, launch phrases, and intent launch phrases. For more details, see Choose the Invocation Name for a Custom Skill.
Interaction Model	Create a custom voice interaction model. For more details, see Create the Interaction Model for Your Skill. Under Interaction Model, you can find the following tools: • Intents – Create and edit intents, slots, and sample utterances. • Annotation Sets – Create and edit groups of annotations. Use the annotation set with the Natural Language Understanding (NLU) evaluation tool to batch test the accuracy of your interaction model. • Intent History – View aggregated, anonymized, frequent utterances and the resolved intents. The history is available for a given locale if your skill has at least 10 unique users in a day in that locale. • JSON Editor – Upload, view, and edit your interaction model in the JSON editor. The editor provides basic validation for JSON syntax errors, such as misplaced commas. For more details about the JSON schema, see Interaction Model Schema.
Assets	Create custom slot types and search for built-in slot types to use in your intents. Every slot included in your interaction model has a type that determines how Alexa handles the spoken data that the user provides. For more details, see Create and Edit Custom Slot Types, Use Slot Types in Alexa Conversations and Slot Type Reference.
Multimodal Responses	Define visual and audio responses for Alexa-enabled multimodal devices. For more details, see Add Visuals and Audio to Your Skill.
Interfaces	Add additional directives and requests for specific features. The following interfaces are available to custom skills: • Audio Player • Video App • Custom Interface Controller for Alexa Gadgets • CanFulfillIntentRequest for Name-free Interactions • Alexa Presentation Language (APL) • Alexa Web API for Games • Alexa Extensions for APL or Web API Extensions for Games • Alexa Conversations • Alexa Shopping Kit • Auto Delegation
Endpoint	Define the endpoint that hosts your service as an Amazon Web Service (AWS) Lambda function or a web service. For Lambda endpoints, select the AWS Lambda ARN option, and then for Default Region, enter the ARN for your function. You can provide multiple endpoints for better latency in other regions. For web service endpoints, select the HTTPS option ,and then Default Region, enter the full URL for your endpoint. You must configure an SSL certificate from a trusted certificate authority, or your endpoint must be a sub-domain of a domain with a wildcard certificate from a trusted certificate authority. For testing purposes, you can create self-signed certificates.
Build History	View previous build versions of your interaction models. Here, you can compare the current model build to a previous build, and copy the previous version of your interaction models to the current version. For more details, see Build history.

The image shows the build progress panel and status of each locale. — Build-in-progress panel

Build history

To view previous builds, select CUSTOM > Build History. Here you can view the latest successful builds. To compare previous interaction models with the current version, under ACTIONS, select View diff. To keep a copy of the current version, make sure that you build the current version. To restore a previous version of your interaction models, under ACTIONS, select Copy build.

Note: If the current version of your model has more locales defined than an earlier version, after you select Copy build, you lose those locales. To keep a copy of the current version, you must build before you copy.

Pre-built models

For prebuilt models, such as connected vehicle, music, smart home, and video skills, the Build page shows the configuration options for the skill. All models support the en-US locale and some models aren't supported in certain locales. Each model requires that you have an AWS Lambda ARN endpoint for the corresponding Endpoint section. Choose the options in the left pane to configure additional information for your skill. Some models require account linking, while account linking is optional or not supported for others. Some models support enabling permissions to obtain customer consent so that your skill can get access to customer information or send information to Alexa.

The following table summarizes the a prebuilt models and provides references for more details.

- The skill can use either authorization code grant (recommended) or implicit grant.
For a skill that includes the connected vehicle, smart home, or video model:
- Account linking is required.
- The skill must use authorization code grant.
For a skill that includes the music model:
- Account linking is optional.
- The skill must use authorization code grant.

For a skill that includes a custom model and either the smart home or video model, the same smart home and video requirements apply.

For more details about how account linking works, see the following:

For details about how you configure account linking, see:

Configure Authorization Code Grant
Configure Implicit Grant (custom skills only)

Permissions

In the left pane, select TOOLS > Permissions or PERMISSIONS to enable your skill to ask the user for permission to access specific information or perform a task, depending on the information that your skill requires. The available permissions depend on the model that you selected when you created your skill.

After you enable a permission, your skill can ask permission of the user to access that information or perform that task. The skill doesn't obtain this permission until the skill user consents to it.

Flash Briefing and music models don't support permissions.

Permissions for custom skills

The following table shows permissions available to custom skills.

Permission Setting	Description
Notifications	If enabled, your skill can request the customer to provide permission in the Alexa app to send notifications to the customer. The Notifications permission isn't visible unless you open an existing skill that uses proactive events. To enable proactive events in your skill, you must use Alexa Skills Kit Command Line Interface (ASK CLI) and modify the skill manifest to include this permission scope. For more details, see Proactive Events API Reference.
Device Address	If enabled, your skill can ask the user for access to the address information configured for the device. Your skill can request either Full Address or Country/Region & Postal Code Only, depending on the information that your skill requires. For more details, see Device Address API.
Customer Name	If enabled, your skill can ask the user for access to the customer name information configured for the device. Your skill can request either Full Name or Given Name, depending on the information that your skill requires. For more details, see Request Customer Contact Information for Use in Your Skill.
