To add Amazon Alexa as a channel to your Kore.ai bot, you must extract supported Dialog Tasks of this bot from the Configurations tab and add to your Amazon Alexa’s Skills. Additionally, you must configure your bot’s Webhook URL as your Alexa Skill Set’s Service Endpoint for the platform to receive messages.
Note: Alexa as a channel must be enabled for bots that are specifically built to work on voice-based channels. Review the following constraints before enabling Alexa as a channel for this bot:
- Enterprise bots that require the user’s authorization to communicate with the bot are not supported.
- If your dialog tasks require the user’s authorization to communicate with external systems, then the platform will push a card with URL information to the Alexa app.
- Intents and entities of only Published Dialog Tasks can be exported to Amazon Alexa. Ensure that your intents and entities adhere to the naming guidelines of Amazon Alexa.
- Not all entity types available in the Kore.ai platform are currently available in Alexa. Verify that your tasks contain Alexa-supported entities for optimal user experience.
- Ensure that your dialog tasks contain one or more utterances.
- If you want to display bot response as templates on supported devices like Echo Show, you must define channel-specific responses/prompts.
- Ensure that your dialog tasks contain the Bot Message node as the last node only. Alexa marks a task as completed if a bot message is displayed without expecting any input from the user.
- Webhook Nodes work asynchronously and are currently not supported.
- Amazon Alexa executes one task at a time and hence Hold & Resume functionality is not supported.
To add the Amazon Alexa channel to your bot, you must:
- Add a New Skill – To enable the Alexa channel to your Kore.ai bot, create a new Alexa skill in the Amazon developer console.
- Configure Interaction Model – Alexa skill can be built in one of the following ways:
- Dialog Migration to extract the dialog tasks from Kore.ai and import them into Amazon Alexa’s Skills. This will entail re-import for reflecting ongoing changes in the dialog definition. Intent detection and execution are primarily controlled by Alexa.
- Redirection to create a single intent in your skill with one SearchQuery slot that accepts user inputs and redirects them to your Kore.ai bot. Intent detection and execution are primarily controlled by the Kore.ai bot.
- Enable Account Linking – To access end user’s authentication details to make API calls to external services. This step is optional.
- Enable Webhook Integration – To integrate Amazon Alexa with your Kore.ai bot, enable webhook integration by copying the Webhook URL provided on the Configurations tab of the Amazon Alexa Channel page in the bot builder and select HTTPS as Service Endpoint type.
- Enable Channel – After completing the integration setup, enable the channel.
- Test Integration – Once the channel is enabled, to validate a successful integration, test any intent utterance using the Test tab of your Alexa Skill and check its responses for the given test utterances.
- Publishing Information, Privacy & Compliance, and Certification – You must publish your Alexa Skill on Alexa App and provide details for Privacy and Compliance to enable Skills Beta Testing that allows you to invite your co-developers to test your app. You must also submit your Skill to Amazon for certification to enable your skill to become visible on Alexa Skills on Amazon App Store after it is certified.
