Building ChatBot

I will use DialogFlow ChatBot for my implementation. Go to https://dialogflow.com/ Sign up for free ( as a Google product you can use your Google Account to sign in ).

ChatBot Framework in general is well documentated you can find a lot of topics talking about this with easy effort.

At first you need to undertsand three things Small Talk, Intents and Entities about ChatBot :

1. Small talk Intents. These intents are the opener or closer of a conversation.
2. Intents ( or Business Intents  ) are the intentions of the end-user, these intentions or intents are conveyed by the user to your bot.
3. Entities are metadata or parametres that compose each intent.

For this scenario i will create two intents GET_AGENTS_LIST and GET_AGENT_ITEM. GET_AGENT_ITEM will contain AGENT_ID as an Entity. Small Talk will be expression like Hi/Hello and Bye or Ciao.

Step by step to create GET_AGENTS_LIST intent

Click Intent link in the left menu to create new intent

Enter GET_AGENTS_LIST in the field name and add few expressions as shown below. Check Use Webhook checkbox and click SAVE button after.

From to left menu clickFulfillement link

Put the XSJS script url, activate ENABLED and add X-CSRF-TOKEN = unsafe ( other wise you get an this error Webhook call failed. Error: 403 Forbidden ) as header param and click SAVE.

Test the Webhook call. Enter an expression of our intent and hit Enter. For more details click SHOW JSON button
