What it does Captures token usage and cost from your AI Agent/LLM. Logs model, tokens, cost, tool use, and conversation I/O to Google Sheets for simple observability and billing. Perfect for Developers adding usage monitoring to AI agents. Teams needing cost transparency in prototypes. How it works Chat Trigger collects user input for the AI Agent. A Set node injects metadata like workflow, execution, and client IDs. LangChain Code node returns a configured Chat model with a callback that reads usage metadata. The callback computes input, output, and total costs based on per‑million token prices you define. It appends token metrics to a Google Sheet via the Google Sheets Tool. The Agent records intermediate tool calls. An If node checks whether a tool was used. When tools are used, the workflow logs input, output, tool name, and metadata to an Observability sheet. How to use SELF-HOSTED N8N ONLY - the Langchain Code node is only available in the self-hosted version of n8n. It is not available in n8n cloud. Requirements Self-hosted version of n8n If you have any questions in running the workflow, see the attached video: https://youtu.be/JSulRS128MA

Workflow Purpose This workflow periodically checks a service's availability and sends an SMS notification if the service is down. High-Level Steps Schedule Trigger: The workflow is triggered at a specified interval, such as every minute. HTTP Request: An HTTP request is sent to the URL of the service being monitored. If: The HTTP status code of the response is checked. If the status code is 200 (OK), the workflow ends. If the status code is not 200, indicating a potential issue, an SMS notification is sent using Twilio. Setup Setting up this workflow is relatively straightforward and should only take a few minutes: Create a new n8n workflow. Add the nodes: Schedule Trigger, HTTP Request, If, and Twilio. Configure the nodes: Schedule Trigger: Specify the desired interval. HTTP Request: Enter the URL of the service to be monitored. If: Set the condition to check for a status code other than 200. Twilio: Enter the Twilio account credentials and the phone numbers for sending and receiving the SMS notification. Connect the nodes: Connect the nodes as shown in the workflow diagram. Activate the workflow: Save the workflow and activate it. Additional Notes The workflow can be customized by changing the interval, the URL, the Twilio credentials, and the SMS message. This workflow is a simple example, and more complex workflows can be created to meet specific needs.

WhatsApp Flows Encrypted Data Exchange Workflow Summary This workflow enables secure end-to-end encrypted data exchange with WhatsApp Flows for interactive applications inside Whatsapp. It implements the WhatsApp Business Encryption protocol using RSA for key exchange and AES-GCM for payload encryption, providing a secure channel for sensitive data transmission while interfacing with WhatsApp's Business API. This follows the official WhatsApp Business Encryption specifications to establish an encrypted GraphQL-powered data exchange channel between your business and the WhatsApp consumer client. How It Works Encryption Flow Webhook Reception: Receives encrypted data from WhatsApp containing: encrypted_flow_data: The AES-encrypted payload encrypted_aes_key: The RSA-encrypted AES key initial_vector: Initialization vector for AES decryption Decryption Process: The workflow decrypts the AES key using an RSA private key Then uses this AES key to decrypt the payload data The inverted IV is used for response encryption Data Processing: The workflow parses the decrypted JSON data Routes requests based on the screen parameter. Response Generation: Generates appropriate response data based on the request type Encrypts the response using the same AES key and inverted IV Returns the base64-encoded encrypted response Key Components Webhook Endpoint**: Entry point for encrypted WhatsApp requests Decryption Pipeline**: RSA and AES decryption components Business Logic Router**: Screen-based routing for different functionality Encryption Pipeline**: Secure response encryption How to Use Deploy the Workflow: Import the workflow JSON into your n8n instance Set Up WhatsApp Integration: Configure your WhatsApp Business API to send requests to your n8n webhook URL Ensure your WhatsApp integration is set up to encrypt data using the public key pair of the private key used in this workflow Test the Flow: Send an encrypted test message from WhatsApp to verify connectivity Check if appointment data is being retrieved correctly Validate that seat selection is functioning as expected Production Use: Monitor the workflow performance in production Set up error notification if needed Requirements Authentication Keys RSA Private Key: Required for decrypting the AES key (included in the workflow) WhatsApp Business Public Key: Must be registered with the WhatsApp Business API PostgreSQL Credentials: For accessing appointment data from the database WhatsApp Business Encryption Setup As specified in the WhatsApp Business Encryption documentation: Generate a 2048-bit RSA Key Pair: The private key remains with your business (used in this workflow) The public key is shared with WhatsApp Register the Public Key with WhatsApp: Use the WhatsApp Cloud API to register your public key Set up the public key using the /v17.0/{WhatsApp-Business-Account-ID}/whatsapp_business_encryption endpoint Key Registration API Call: POST /v17.0/{WhatsApp-Business-Account-ID}/whatsapp_business_encryption { "business_public_key": "YOUR_PUBLIC_KEY" } Verification: Verify your public key is registered using a GET request to the same endpoint Ensure the key status is "active"
