    https://www.youtube.com/watch?v=qHKCgCusee4&list=PLyOJN_bAzw3jcOxupqianlvqM9f_rwW1g

    This article will present a guide to integrating LINE Chatbot with Dialogflow and Google Gemini AI, using the Make.com platform as an intermediary to connect workflows. The core principle is to leverage Dialogflow’s conversation management capabilities, Google Gemini AI’s advanced natural language processing power, and Make.com’s automation workflow creation flexibility to create a smarter and more natural conversational experience on LINE.

    You can learn more about Make.com courses from the official website (Make.com Academy) at https://academy.make.com/pages/search

    The content in this article is divided into 5 stages. as follows

    1. Start creating a workflow with Make.com
    2. Implementation of the “Google Cloud Dialogflow ES (Watch for Fulfillment)” module
    3. Manage Responses in Default Fallback Intent and Enable Fulfillment
    4. Using the “Google Gemini AI (Create a completion)” module
    5. Using the “LINE (Send a Reply Message)” Module

    1. Start creating a workflow with Make.com

    Go to the URL: https://www.make.com/ will appear on the screen, as shown in the image.

    Complete the login registration, you will find this screen.

    Press the Create a new scenario button on the top right of the screen, and the screen will appear. There will be Apps or Modules to choose from, as shown in the picture.

    2. Implementation of the “Google Cloud Dialogflow ES (Watch for Fulfillment)” Module

    Search for the Google Cloud Dialogflow ES module by typing in the search box as shown in the image.

    Then, click Show more to display all the results and select “Watch for Fulfillment” as shown in the image.

    Once selected, you will get the module you want, as shown in the picture.

    Then, press the “Create a webhook” button, name the Webhook name, and press the “Create a connection” button as shown in the picture.

    When the button is pressed, a screen will appear to enter the Client ID and Client Secret as shown in the picture.

    We need to find the Client ID and Client Secret from Google Cloud Platform, go to URL: https://console.cloud.google.com/ and select the Project to create the agent in Dialogflow, or go back to Dialogflow and press the gear symbol.

    Once on Google Cloud Platform, search for dialogflow. Select the Dialogflow API as shown in the image.

    Once pressed, the Dialogflow API screen will appear. Then, press the “Manage” button.

    When pressed, a screen will appear as shown in the picture in the “Create credentials” button located in the upper right.

    Once you’re on the Credential creation screen, select “User data” as shown in the image and press Next.

    Once pressed, a screen will appear, as shown in the picture, specify the App name and email and press the Save and continue button.

    For Scopes, press the Save and continue buttons, and the screen will appear as shown in the picture.

    On this screen, select Application type as Web Application and enter a name, then press the “Create” button.

    At this point, we will get the Client ID, press the Done button. Then click “Credentials” menu in navigation in the left side. And then click “Make” app in OAuth 2.0 Client IDs as shown in the picture.

    At this stage we will find the Client ID and Client Secret.

    At this point, there is still one step left: adding Authorized redirect URIs to add https://www.integromat.com/oauth/cb/google-custom

    Then, copy your Client ID and Client Secret into the Make.com as shown in the picture, and don’t forget to click Save in the Credentials section where the Authorized redirect URIs are added.

    Once the Authorized redirect URIs section is saved, go to the Make.com and click the Sign in with Google button and select the email used to create the agent in Dialogflow.

    When you press the Save button, a screen will appear as shown in the picture, which shows the webhook to be copied to be stored in the Dialogflow Fulfillment.

    3. Manage Responses in Default Fallback Intent and Enable Fulfillment

    Once we’ve reached the “Default Fallback Intent“, go to the Responses section to delete all the data used in the response and activate the fulfillment as shown in the image.

    We do this because we don’t want Dialogflow to answer any data back, but instead send the question to the Make.com for processing through fulfillment. Now, if we send any message or question to Dialogflow, there will be no reply.

    Then, take the webhook from the Watch for Fulfillment module and enter it in the URL field in the Fulfillment menu as shown in the image, then press the “Save” button at the bottom.

    Try testing it by pressing the Run button once.

    When pressed, it will be displayed as shown in the picture.

    Try sending any non-intent messages in Dialogflow, which will go to the Fallback Intent and forward it to make.com.

    4. Use of the “Google Gemini AI (Create a completion)” module

    Press the + button to add the module as shown.

    Search for Gemini and choose “Show more”, and then select module “Create a Completion” as shown in the image.

    Once selected, a screen will appear, as shown in the picture.

    If you don’t have an API key, go to https://aistudio.google.com/ and sign in with the account you used to create an agent in Dialogflow as shown in the picture, then click the “Get API key” button.

    Then the screen will appear as shown in the picture, press the “Create API key” button.

    Then, select the project you use, and then press the Create API key in existing project.

    Note: Other Project API keys can be used. It doesn’t have to be the same project as Dialogflow.

    Once you get the API key, copy it. Then go back to Make.com, click “Create a connection” button and paste the API key as shown in image. And click “Save” button.

    Then, select the Model such as Gemini 2.5 Flash, then select (Model) Input as shown in the image, which will assign the role to this module.

    Then, press the Add item button, select the (User) details as shown, then press “Save”.

    5. Using the “LINE (Send a Reply Message)” Module

    Press the + button to add a module and search for LINE as shown in the picture.

    Then click Show more to select “Send a Reply Message” as shown in the picture.

    Once selected, a screen will appear, as shown in the picture.

    Press the “Create a connection” button, and a screen will appear to enter the “Channel Access” Token from https://developers.line.biz/.

    When you enter the Channel Access Token and press the “Save” button, the screen will appear.

    Select Reply Token and Reply by example as shown in the show.

    In case you could not see “replyToken” in “data“, try to click the “Run once” button at the bottom.

    Then you will see the component “Google Cloud Dialogflow ES” is running and waiting for the input (in feedback intent) as image below.

    You then can type in your chatbot with any messages that will go to your fallback intent (which is not in your created intents). Once the “Google Cloud Dialogflow ES” is activated, you will be able to see “replyToken” under “Original Detect Intent Request” -> “Payload” -> “data”. Now you can just drag and drop the “replyToken” element to “Reply Token”.

    According to the example, the Reply Token forwarded from Dialogflow will be used in the reply by using the result from Gemini, which when the example is specified, press the “Save” button and then test the chatbot.

    Once Save, a screen will appear as shown in the picture.

    Select the Scenario that you created, and then activate this Scenario, as shown in the image.

    Then type in a sample question, such as “what does ICDI stand for?”. The system will help answer the required information, but if asked, “who is dean?” the system will answer, “The provided text doesn’t name the dean of the …” which is according to the prompt set.

    Error Handling

    To prevent the scenario automatically is stopped after any face problems. We can “Add error handler” module after “LINE” module.

    Choose “Ignore” module

    Finally, the full workflow will be shown as following figure:

    In this article, we explain the process of using the Make.com platform as an intermediary to connect work processes by receiving data from Dialogflow Fulfillment, processing it with Gemini, and replying with a Reply Message.
