Calling Webhook

This tutorial walks you through creating a custom tool in AiMicromind that calls a webhook endpoint, passing the necessary parameters in the request body. We will use Make.com to set up a webhook workflow that sends messages to a Discord channel.

Setting Up a Webhook in Make.com

1. Sign up or log in to Make.com.

2. Create a new workflow containing a Webhook module and a Discord module, as shown below:

   

3. From the Webhook module, copy the webhook URL:

   

4. In the Discord module, configure it to pass the message from the webhook body as the message sent to the Discord channel:

   

5. Click Run Once to start listening for incoming requests.

6. Send a test POST request with the following JSON body:

   {
       "message": "Hello Discord!"
   }
   

   

7. If successful, you will see the message appear in your Discord channel:

   

Congratulations! You have successfully set up a webhook workflow that sends messages to Discord. 🎉

Creating a Webhook Tool in AiMicromind

Next, we will create a custom tool in AiMicromind to send webhook requests.

Step 1: Add a New Tool

1. Open the AiMicromind dashboard.

2. Click Tools, then select Create.

   

3. Fill in the following fields:

   Field	Value
   Tool Name	make_webhook (must be in snake_case)
   Tool Description	Useful when you need to send messages to Discord
   Tool Icon Src	AiMicromind Tool Icon

4. Define the Input Schema:

   

Step 2: Add Webhook Request Logic

Enter the following JavaScript function:

const fetch = require('node-fetch');
const webhookUrl = 'https://hook.eu1.make.com/abcdef';
const body = {
    "message": $message
};
const options = {
    method: 'POST',
    headers: {
        'Content-Type': 'application/json'
    },
    body: JSON.stringify(body)
};
try {
    const response = await fetch(webhookUrl, options);
    const text = await response.text();
    return text;
} catch (error) {
    console.error(error);
    return '';
}

5. Click Add to save your custom tool.

   

Step 3: Build a Chatflow with Webhook Integration

1. Create a new canvas and add the following nodes:

   • Buffer Memory
   • ChatOpenAI
   • Custom Tool (select make_webhook)
   • OpenAI Function Agent

2. Connect them as shown:

   

3. Save the chatflow and start testing it.

Step 4: Sending Messages via Webhook

Try asking the chatbot a question like:

"How to cook an egg?"

Then, request the agent to send this information to Discord:

You should see the message appear in your Discord channel:
