Make a chatbot with n8n

Creating a chatbot with N8n is easy and requires no coding experience. Follow these simple steps to get started:

Sign Up for n8n

If you aren’t already signed up, create an account on n8n for a 14-day trial. Sign in as shown below:

Now let’s set up the workflow to develop a telegram chatbot.

Create a Workflow

In the dashboard, will click on ‘Workflow’ to create a first no-code chatbot. Then, selecting the workflow that I’ve created to make edits for the chatbot, as shown in the figure below.

After creating a workflow, the next step is to set up the credentials required for integrating with Telegram and OpenAI.

Create Credentials

Connect Telegram with N8n

To integrate your chatbot with Telegram, you’ll need to create credentials. Follow these steps:

1. Open the Telegram website or desktop app and sign in to your account.

2. Navigate to the Telegram BotFather, as shown in the figure below:

Connect Telegram with N8n

The first step is to initiate a conversation with BotFather. To do this, type “/newbot” in the chat with BotFather. Following this, you’ll be prompted to provide a name for your chatbot. It’s important to note that the word “bot” must be included in the name you choose, as shown in the figure. This ensures that your chatbot is properly recognized and categorized within the Telegram ecosystem.

After providing the name, BotFather will generate an HTTP API token, which you’ll need to use in the N8n credentials for Telegram. This token acts as a unique identifier for your chatbot and allows it to communicate with Telegram’s API seamlessly.

To establish a connection between your Telegram account and N8n, simply incorporate the generated HTTP API token into the N8n Telegram credential. This integration enables seamless communication between Telegram and N8n, facilitating the operation of your chatbot with ease.

Telegram account successfully connected, it’s time to integrate OpenAI for enhanced chatbot functionality. Let’s seamlessly link OpenAI to further enhance the capabilities of your chatbot.

Link OpenAI with N8n

To connect your chatbot to the OpenAI model, you’ll need API credentials. Here’s how to get started:

1. Sign up for an account on the OpenAI website.

2. Once logged in, generate an API key from the dashboard.

1. Utilize this API key to authenticate your chatbot’s access to the OpenAI model within N8n credentials, as demonstrated below.

Integrate Telegram & OpenAI to create ChatBot

Step 1

Add a Telegram trigger to the workflow and follow the steps below to configure its settings:

1. Credential to connect with: Utilize the previously created Telegram credential, as demonstrated above.

2. Trigger On: Choose “message” to activate the trigger whenever a message is sent to the chatbot on Telegram.

Step 2

Next, incorporate an “IF” node into the workflow and proceed with the following steps to adjust its settings:

1. Conditions: Establish the condition as ‘{{ $json.message.text }}’ “is equal to” to retrieve the text of the message triggered from Telegram. Set the value2 as ‘/start’.

Step 3

Integrate a second “IF” node into the workflow and continue with the following steps to customize its settings:

1. Condition: Define the condition as ‘{{ $json.message.chat.id }}’ “is equal to” to retrieve the identifier of the chat from the Telegram message. Set the value2 as ‘your_chat.id’, for example, ‘121883958’.

Step 4

Now, when the “IF” node condition evaluates to true, it should be linked with the “Telegram SendChatAction” node. Let’s configure the “Telegram SendChatAction” node with the following steps:

1. Credential to connect with: Utilize the previously created Telegram credential, as demonstrated above.

2. Resource: Set the resource as ‘message’.

3. Operation: This should be set as “Send Chat Action”.

4. Chat ID: Set the expression as {{ $(‘Telegram Trigger’).item.json.message.chat.id }}.

5. Action: Specify the action as ‘Typing’.

Step 5

Let’s create a node for OpenAI, it should be connected with the OpenAI node to generate a response for the query. Let’s configure the “OpenAI” node with the following steps:

1. Credential to connect with: Utilize the previously created OpenAI credential, as demonstrated above.

2. Resource: Set the resource as ‘Text’.

3. Operation: Choose “Message a Model” from the options.

4. Model: Choose “Message a Model” from the options.

Step 6

Now, the Telegram Action is used to send the response to the chatbot user. Let’s configure the “Telegram Action” with the following steps:

1. Credential to connect with: Utilize the previously created OpenAI credential, as demonstrated above.

2. Resource: Set the resource as ‘message’.

3. Operation: This should be set as “Send Message”.

4. Chat ID: Set id to ‘{{ $node[‘Check Id of Chat’].json.message.chat.id }}’

5. Text: Set text to ‘{{ $node[‘Generate Response’].json.message.content }}’

Finally, develop a workflow for a chatbot that seamlessly integrates with the OpenAI model, enabling it to provide real-time responses to user queries. Below, you’ll find a visual representation of the template.
