Sample Alexa Skill

Creating an Alexa skill called acme insurance along with a Webhook channel lets you chat with a specific bot.

Requirements

Set up a developer account in the Amazon Developer Portal. Choose Alexa Skills Kit.

Configuring the singleBot Skill

Create a Webhook Channel

In the Bot Builder, create a webhook channel for your bot:

1. In the Create Channel dialog, enter the outgoing Webhook URL as https://YOUR_PUBLIC_FACING_URL/singleBotWebhook/messages. This URL is where your bot will send its responses back to the Alexa skill.

2. Keep the Secret Key and Webhook URL close by because you need to add them to the service.js file. Also, remember to set the amazon skill id (to be created in the next step). For example:

    var metadata = {
    waitForMoreResponsesMs: 200,
    amzn_appId: "amzn1.ask.skill.b6a603ad-5f3f-471e-b509-922ddc2aded9",
    channelSecretKey: 'RpBrYK14O48vQXxDMOpYw32j7q8O8B8J',
    channelUrl: 'http://bots-connectors:8000/connectors/v1/tenants/5c82a414-e2d0-45fd-b6a2-8ca3b9c09161/listeners/webhook/channels/E8D22577-3F91-487F-9018-1D6E884DED1A'
    };
   

3. Save the file.
