n8n Bitrix24 Chatbot Application Workflow Example with Webhook Integration

This n8n workflow demonstrates a basic structure for handling incoming webhook requests, processing them with custom logic, making an HTTP request, and responding to the original webhook. While the specific integration with Bitrix24 for a chatbot application is implied by the directory name, the provided JSON focuses on the core n8n logic for receiving, transforming, and responding to webhook data.

What it does

This workflow is designed to:

1. Listen for incoming data: It starts by waiting for a webhook trigger.
2. Process incoming data: It uses a Function node to execute custom JavaScript code, likely to parse or transform the incoming webhook payload.
3. Make an external request: It then sends an HTTP Request, which could be used to interact with an external API (e.g., Bitrix24, a custom chatbot service, or a large language model).
4. Conditional Logic: A Switch node is used to route the workflow based on certain conditions derived from the processed data or the HTTP request response.
5. Set Data: An Edit Fields (Set) node is used to manipulate or add data to the workflow items.
6. Handle different paths: An If node further branches the workflow based on conditions, leading to different actions.
7. Respond to the webhook: Finally, it responds to the initial webhook request, potentially sending back a message or status.
8. No Operation: Includes a No Operation node, which acts as a placeholder or a way to terminate a branch without performing any action.

Prerequisites/Requirements

• An n8n instance (self-hosted or cloud).
• Understanding of JavaScript for the Function node.
• Knowledge of the API you intend to call with the HTTP Request node.
• A service that can send webhook requests to your n8n instance.

Setup/Usage

1. Import the workflow:
   • Copy the provided JSON code.
   • In your n8n instance, click "New" to create a new workflow.
   • Go to the "Workflows" menu, click "Import from JSON", and paste the copied JSON.
2. Configure the Webhook Trigger:
   • The Webhook node (ID: 47) will have a unique URL once activated. Copy this URL.
   • Configure your external service (e.g., Bitrix24, a form, or another application) to send POST requests to this URL.
3. Customize the Function Node:
   • Open the Function node (ID: 14).
   • Modify the JavaScript code to parse and transform the incoming webhook data according to your needs. For a chatbot, this might involve extracting user messages, sender IDs, or command keywords.
4. Configure the HTTP Request Node:
   • Open the HTTP Request node (ID: 19).
   • Set the URL, Method, Headers, and Body to interact with your desired API (e.g., Bitrix24 API to send a message, or an AI service to generate a response).
5. Adjust Logic Nodes:
   • Switch Node (ID: 112): Configure the conditions in this node to route the workflow based on values from previous nodes (e.g., if a specific command was detected).
   • If Node (ID: 20): Further refine your conditional logic here based on the results of the HTTP request or other data transformations.
6. Configure Edit Fields (Set) Node:
   • Open the Edit Fields (Set) node (ID: 38).
   • Define what data you want to add or modify in the workflow item, which can then be used in subsequent nodes, including the webhook response.
7. Configure Respond to Webhook Node:
   • Open the Respond to Webhook node (ID: 535).
   • Set the Response Mode and Body to send the appropriate response back to the service that triggered the webhook. For a chatbot, this would be the message displayed to the user.
8. Activate the workflow: Once configured, activate the workflow to start listening for incoming webhooks.
