n8n Bitrix24 Task Form Widget Application Workflow with Webhook Integration

This n8n workflow automates the processing of data submitted through a form, conditionally handling it based on a specific field, and potentially generating a file. While the original directory name suggests a Bitrix24 task form widget, the provided JSON primarily focuses on data transformation, conditional logic, and file operations.

What it does

This workflow performs the following key steps:

1. Listens for incoming data: It starts with a Webhook node, waiting for incoming HTTP POST requests.
2. Processes incoming data: A Function node takes the incoming webhook data and transforms it, likely extracting specific fields or restructuring the payload.
3. Applies conditional logic: An If node evaluates a condition based on the transformed data.
4. Conditional Path 1 (True): If the condition is true:
   • It modifies fields using an "Edit Fields (Set)" node.
   • It then converts the data into a file format using the "Convert to File" node.
   • Finally, it writes this file to disk using the "Read/Write Files from Disk" node.
5. Conditional Path 2 (False): If the condition is false:
   • It modifies fields using a different "Edit Fields (Set)" node.
   • It then processes the data with a "Code" node, likely for further custom logic or transformation.
   • It then extracts data from a file (or prepares data for extraction) using the "Extract from File" node.
   • Finally, it makes an HTTP request to an external API.
6. Merges and Responds: Both conditional paths converge into a Merge node, combining their outputs. The workflow then responds to the initial webhook request with the final processed data.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance to import and execute the workflow.
• Webhook Integration: An application or service configured to send HTTP POST requests to the n8n webhook URL.
• External API (Optional): If the "HTTP Request" node is configured to call an external API, you will need the necessary API endpoint and authentication details.
• File System Access (Optional): If the "Read/Write Files from Disk" node is configured to save files, your n8n instance needs appropriate write permissions to the specified directory.

Setup/Usage

1. Import the Workflow:
   • Copy the provided JSON code.
   • In your n8n instance, go to "Workflows" and click "New".
   • Click on the "Import" button (usually a cloud icon with an arrow pointing down) and paste the JSON code.
   • Click "Import".
2. Configure the Webhook:
   • Locate the "Webhook" node (the first node in the workflow).
   • Copy the "Webhook URL". This is the URL you will send your data to.
3. Configure Node Logic:
   • Function (Node 14): Review and adjust the JavaScript code within this node to correctly parse and transform your incoming webhook data according to your needs.
   • If (Node 20): Define the condition(s) that will determine which path the workflow takes (True or False).
   • Edit Fields (Set - Node 38 & Node 834): Adjust the fields to be set or modified in both the "True" and "False" branches.
   • Convert to File (Node 1234): Configure the desired file format and content if the "True" branch is taken.
   • Read/Write Files from Disk (Node 1233): Specify the file path and name where the generated file should be saved. Ensure n8n has write permissions to this location.
   • Code (Node 834): If the "False" branch is taken, review and modify the JavaScript code for any custom processing.
   • Extract from File (Node 1235): Configure how data should be extracted from a file (or prepared for extraction) if the "False" branch is taken.
   • HTTP Request (Node 19): If the "False" branch is taken, configure the URL, method, headers, and body for the external API call.
4. Activate the Workflow: Once configured, activate the workflow by toggling the "Active" switch in the top right corner of the n8n editor.
5. Send Data: Send an HTTP POST request to the Webhook URL you copied in step 2 with the relevant data in the request body.
