Instructions

• Create a Facebook developer account in order to use their graph API

• Create a new App

• On the App's Settings -> Basics page make sure to add a website platform. (This is necessary so we can enable facebook login for oauth2 verificaton)

• Under Products, select Add Product, then choose Facebook Login

• Make sure to keep the facebook app page open as we will need it later for the oauth2 setup.

• Follow this guide to create a lambda function for the skill.

• On the aws developer portal, click Add a new skill

• Populate the Skill Information

• Under Interaction Model add the intent schema

{ 
   "intents": [ 
       { 
           "intent": "AMAZON.PauseIntent" 
       }, 
       { 
           "intent": "AMAZON.ResumeIntent" 
       }, 
     	{ 
     "intent": "TellMeAbout", 
     "slots": [ 
       { 
         "name": "date", 
         "type": "AMAZON.DATE" 
       } 
     ] 
   } 
   ] 
} 

• Populate sample Utterances

TellMeAbout Tell me about {date} 
TellMeAbout What happened on {date} 
TellMeAbout What happened in {date}  

• Under configuration select AWS Lambda ARN and populate the lambda function's ID Under North America. (You can find the id in the aws console)

• Under account linking is where we will configure oauth2 with facebook.

If you get lost / confused have a look at this guide from facebook. The URLs can be copied and pasted from there.

client id is your facebook app id

• Head on over back to the facebook developer portal and set up the oauth2 redirect URLs you see on the aws portal Account Linking screen

• Congratulations, your alexa skill can now link to facebook!

Unfortunately we are using the user_posts permission which requires approval from facebook, so for development purposes we will be using the facebook graph explorer's token for requests.

• Get your developer access token with the user_posts permission enabled

• Click Get Token

• Make sure the user_posts permission is checked

• You now have a token! We will use it shortly.

• Download the github project

• Run npm install

• Set DEVELOPER_ACCESS_TOKEN to the token you got from the facebook graph API

• Zip up the nodejs application (including the node_modules folder).

• Upload to the lamdbda function

• Click save, once completed the skill will use the updated code.

• Don't forget to enable the skill for your alexa app. The skill will appear in the Your Skills section of the smartphone app.

• It will appear at the bottom
