1. Intro

On this repo, you will find a very small Dialogflow fulfillment that allows integrating your chatbots with IFTTT applets.

Dialogflow is a Google platform that facilitates the creation of chatbots. You can configure your intents and replies easily with a visual interface. You can connect your Dialogflow chatbots with a lot of platforms ( Facebook Messenger, Telegram, Google Assistant, … ).

If you want to create a chatbot that speaks with third-party services ( Gmail, Spotify, … ) you need to create a fulfillment webhook and develop a connector on your servers.

The objective of this project is to facilitate the integration of third-party services with the help of IFTTT.

IFTTT is a platform where you can configure connections between hundreds of services.

2. Example

On this example, we are going to create a small poll with a chatbot. The replies will be saved on Google Drive.

Step 1: Create a IFTTT applet:

1. Create a new IFTTT account.
2. Go to IFTTT New Applet.
3. Click on +this.
4. Search webhooks.
5. Select Receive a web request.
6. Write an event name. We are going to use poll_completed.
7. Click on +that.
8. Search Google Sheets.
9. Select Add a row to spreadsheet.
10. Click Create action.
11. Click Finish.

Step 2: Deploy the webhook:

1. Create a Heroku account.
2. Click on this button:
3. Write an app name and choose a region.
4. Click Deploy app
5. Wait until webhook be deployed.
6. Click on View and you will be redirected to your app. Default user is test and default password is test. Remember change them.
7. This control panel will allow you to connect your chatbot intents to IFTTT applets.

Step 3: Create your intent:

1. Open a browser and log in to Dialogflow.
2. Click Create agent in the left menu.
3. Enter your agent's name, default language, and default time zone, then click the Create button.

4. Create a new intent with this features:

   • Intent name. We will use bot.example.poll.

   • Some training phrases. For example: i want to complete the poll, complete the poll, reply the poll.

   • Two required params:

     • value1 - @sys.given-name - $value1. Prompt: Your name?.
     • value2 - @sys.number - $value2. Prompt: Your age?.

     

   • A response: Thanks for reply our survey.

5. Activate Fulfillment on Fulfillment > Enable webhook call for this intent..
6. Save intent.
7. Insert your Fulfillment URL on Fulfillment section. Fulfillment URL appears on Heroku control panel (you installed it on previous section).

Step 4: Connect all.

1. Go to Heroku control panel.
2. Insert and Save IFTTT Events URL.
3. Insert connections. The first row contains Dialogflow intents. The second row contains IFTTT events. On this example you should insert:
   • Intent: bot.example.poll.
   • Action: poll_completed.
4. Save Connections.

Step 5: Test

1. Go to Integrations on Dialogflow.
2. Enable Web Demo.
