Chatbot builders have made this cutting-edge technology accessible and affordable for businesses with budget and resource restrictions. Appy Pie Chatbot has emerged as the perfect solution for startups and enterprises alike by offering no-code chatbot development with excellent outcomes.

In this blog, we will discuss Dialogflow, the natural language understanding platform from Google, how to make a chatbot using Dialogflow, limitations of Dialogflow, and discuss the advantages of no-code chatbot development with Appy Pie Chatbot as well.

What is Dialogflow?

Dialogflow is a popular natural language processing (NLP) platform. It is an excellent tool for creating conversational applications like chatbots to help companies provide an evolved customer experience. Powered by Google, Dialogflow lets the developers create text-based and voice-based chatbots to serve their customers and provide an engaging experience.

Benefits of Dialogflow

Dialogflow has gained popularity among the developers, and here are the reasons why:
  • Dialogflow is known for being user-friendly and intuitive. The platform has an integrated code editor and a serverless application structure.

  • The platform offers multilingual integrations in more than 20 languages.

  • Dialogflow offers software development kits for a variety of devices, including mobile devices, wearables, cars, and other smart devices.

How do Dialogflow chatbots work?

Here are the steps to showcase the process in which your Dialogflow chatbot works:
  1. A user comes to your platform and enters their query through text or voice message through a device.

  2. The device sends the message to Dialogflow.

  3. This message is then categorized and matched to a corresponding intent.

  4. Each corresponding action is defined in the fulfillment.

  5. Once Dialogflow finds a particular intent, the webhook uses external APIs to look for the relevant response in external databases.

  6. These external databases then send the relevant responses to the webhook.

  7. Next, the webhook sends the formatted response to the intent.

  8. Now, the intent generates actionable data depending on the channels.

  9. This actionable data then goes out to the device.

  10. Finally, the user gets the desired response.

How to make Dialogflow chatbot?

You can make your own Dialogflow chatbot, Dialogflow voice chatbot, or even Dialogflow FAQ bot by following these simple steps below. Create an agent1. Go to Dialogflow, create your own account (if you do not have one already), and log in. 2. In the left navigation menu, click on the “Create Agent” option and fill in all the required fields. 3. Give your agent a name and select the preferred language. Finally, click the ‘Save’ button.Create an intentBefore you start creating your first intent, you must know what intent is. An intent essentially is the element that matches your user query with the desired agent action. Here is how you can create an intent on Dialogflow: 4. First, click on the plus icon next to intents. 5. Enter the name of your intent. Though you can name it whatever you want, a good thumb rule is to make it indicative of the intent’s goal. 6. Now, go to the Training Phrases section. Here, you can enter as many iterations of the user’s query as you can. Of course, the more iterations you include here, the greater the chances of the agent understanding the user query. 7. Click ‘Save’.Add responseYou have created an agent to ensure that the users’ queries are met with appropriate responses. This is the time to supply the responses to the agent. 8. Just like how you entered all the likely iterations of queries entered by the users, you now need to come up with the appropriate agent response to each possible iteration. 9. Click the ‘Save’ button.Test the agentType in a request in the console to test your Dialogflow chatbot. During this test, you can try to vary the query a little from the phrases you entered in the Training Phrases section. Hit ‘Enter’ after typing in your query, and the following should happen.
  • The agent should provide an appropriate response based on the values you provided
  • The proper intent must be triggered.
  • The response must reflect the appropriate values as entered in the training phrases section.
Basic fulfillment (Webhooks)In some instances, this may prove to be insufficient. In these cases, you can get additional data from external databases using external APIs and by defining custom Webhooks. You can write your webhooks in Python or Node.js and hold them on cloud servers like Heroku, AWS, and Google Cloud Platform, or even a local server if you wish. Dialogflow chatbot IntegrationYour Dialogflow chatbot can be integrated with the most popular apps and voice assistants through a mere click of a button.

Limitations of Dialogflow

Yes, Dialogflow is popular. Yes, it comes from the tech giant - Google. But, that does not mean it comes without its own set of limitations and shortcomings. Let’s discuss.
  • Lack of reusability
  • Though the platform is fairly intuitive and easy to use, it lacks flexibility and maneuverability. One of the most common challenges developers face is that they cannot just drag and move a follow-up response from one intent to another. They will have to delete the entire intent, go to the new desired location, and create an intent from scratch, including re-typing all the training phrases again.
  • Number of Webhooks
  • With Dialogflow, you can only add one Webhook for one project. It may not seem like a big deal to begin with, however, it does become a bit of a challenge down the line. You will be able to use just one webhook for the entire chatbot instead of having webhooks for an intent.
