Description
Overview
This Bitrix24 chatbot application workflow example with webhook integration implements a chatbot management and response automation workflow. This orchestration pipeline supports event-driven analysis of various Bitrix24 chatbot events such as message receipt, chat join, app installation, and bot deletion. The workflow is designed for developers and integrators who need a reliable backend automation workflow to handle Bitrix24 chatbot webhook events and respond accordingly using Bitrix24 REST API calls.
Key Benefits
- Automates chatbot event handling with precise routing of message, join, install, and delete events.
- Validates incoming requests using application token to ensure secure, authenticated webhook calls.
- Processes and transforms incoming chatbot messages into appropriate reply responses automatically.
- Integrates directly with Bitrix24 REST API endpoints for message sending and bot registration.
Product Overview
This no-code integration workflow begins with an HTTP POST webhook node named “Bitrix24 Handler” listening on a specified URL path to receive chatbot events from Bitrix24. Incoming payloads include authentication tokens and event data. The workflow extracts credentials such as CLIENT_ID, CLIENT_SECRET, application_token, domain, and access_token from the webhook payload using a “Set” node. A conditional “If” node validates the application token to verify request authenticity. If validation passes, a “Switch” node routes execution based on the event type field, handling four key Bitrix24 chatbot events: message addition, bot joining chat, app installation, and bot deletion. Each event branch executes a separate function node to process the event payload accordingly, either generating reply messages or preparing bot registration data. HTTP Request nodes send messages or register the bot via Bitrix24 REST API, using OAuth-like tokens extracted dynamically. The workflow concludes with a webhook response node returning a JSON success confirmation. Error responses with HTTP 401 are returned if token validation fails. This synchronous request-response model processes each webhook event in real time without persistent storage, relying on transient token validation and API calls.
Features and Outcomes
Core Automation
This automation workflow ingests webhook events from Bitrix24, then routes based on event type to deterministic processing branches. It includes token validation and event-specific message handling functions.
- Single-pass evaluation of event type via Switch node ensures targeted processing.
- Strict token matching reduces unauthorized requests before processing.
- Function nodes generate tailored responses based on message content or event kind.
Integrations and Intake
The orchestration pipeline connects with Bitrix24 via webhook intake and REST API calls using bearer tokens. Incoming webhook requests contain structured event data and authentication tokens.
- Webhook Listener node receives HTTP POST requests from Bitrix24 chatbot events.
- HTTP Request nodes post messages and register bots through Bitrix24 REST endpoints.
- Authentication uses dynamic application_token and access_token extracted from webhook payload.
Outputs and Consumption
Outputs consist of JSON-formatted responses sent synchronously as HTTP webhook replies and REST API calls posting chatbot messages or registration data back to Bitrix24.
- Chat messages sent via REST API parameters: DIALOG_ID, MESSAGE, and AUTH token fields.
- Bot registration includes event handler URLs and bot metadata in JSON body.
- Webhook responds with JSON { “result”: true } or error JSON with HTTP 401 on invalid tokens.
Workflow — End-to-End Execution
Step 1: Trigger
The workflow is initiated by an HTTP POST webhook request to the specified path (bitrix24/handler.php). Bitrix24 sends event payloads including authentication tokens and event identifiers. The request uses content-type application/x-www-form-urlencoded.
Step 2: Processing
Incoming webhook data is parsed to extract static client credentials and dynamic authentication tokens from the payload’s auth object. Basic presence checks confirm required token fields exist. The tokens are assigned to internal variables for downstream use.
Step 3: Analysis
The workflow validates the application token by comparing the received token against the expected CLIENT_ID. If valid, routing logic uses a Switch node to direct processing based on the event type string. Supported event types include ONIMBOTMESSAGEADD, ONIMBOTJOINCHAT, ONAPPINSTALL, and ONIMBOTDELETE.
Step 4: Delivery
Depending on event type, the workflow executes function nodes to build response messages or registration data. HTTP Request nodes deliver messages or register the bot through Bitrix24 REST API endpoints using POST requests with required authentication tokens. Responses are sent synchronously as JSON confirming operation success or failure.
Use Cases
Scenario 1
A company needs to automate chatbot responses in Bitrix24 to handle incoming messages efficiently. This workflow receives messages via webhook, validates authentication, and replies with either a predefined greeting or an echo of the user’s input. The result is consistent, real-time chatbot interaction without manual intervention.
Scenario 2
When a chatbot joins a new chat, administrators want to send an automated welcome message. This orchestration pipeline detects the join event via webhook and posts a friendly introduction message through Bitrix24’s API, ensuring every new chat includes bot onboarding communication automatically.
Scenario 3
During chatbot application installation, developers require automated registration of the bot with Bitrix24. This workflow handles the install event by preparing and sending registration details, including event handler URLs and bot properties, enabling seamless integration and event subscription setup.
How to use
Import the workflow into n8n and configure the webhook node with the desired path accessible by Bitrix24. Ensure client credentials are set correctly in the credential assignment node. Set up Bitrix24 to send chatbot event webhooks to the configured URL. The workflow runs automatically on incoming events, validating tokens and routing events to corresponding handlers. Monitor workflow executions in n8n for errors. Expect synchronous JSON responses confirming successful processing or failure. Adjust function node logic as needed to customize chatbot replies or registration data.
Comparison — Manual Process vs. Automation Workflow

FAQ
How is the Bitrix24 chatbot application workflow triggered?
The workflow triggers upon receiving an HTTP POST webhook request from Bitrix24 to a configured endpoint path. Each request contains event data and authentication tokens initiating the automation pipeline.
Which tools or models does the orchestration pipeline use?
The pipeline uses webhook listener nodes, conditional and switch nodes for event routing, function nodes for message processing, and HTTP Request nodes to interact with Bitrix24 REST API. It relies on token validation logic for security.
What does the response look like for client consumption?
The workflow returns JSON responses indicating success with { “result”: true } or failure with an error message and HTTP 401 status on invalid application tokens.
Is any data persisted by the workflow?
No data persistence occurs within the workflow. All token values and event data are transiently processed in memory during execution without storage.
How are errors handled in this integration flow?
Errors related to invalid application tokens result in immediate HTTP 401 JSON error responses. Other errors rely on n8n’s platform default retry and failure handling mechanisms.
Conclusion
This Bitrix24 chatbot application workflow enables deterministic and secure handling of chatbot events via webhook integration, automating message responses and bot registration processes. By validating application tokens and routing event types precisely, it ensures consistent chatbot interactions and operational integrity. The workflow’s synchronous request-response model facilitates real-time communication without data persistence, though it depends on continuous Bitrix24 API availability for full functionality. This setup provides a maintainable and scalable automation pipeline for chatbot backend processing within the Bitrix24 ecosystem.
