This workflow integrates HetrixTools with WhatsApp via the GOWA API to automate notifications about server monitoring events. It distinguishes between Uptime Monitoring and Resource Usage Monitoring events, formats the message accordingly, and sends it to a WhatsApp number using the GOWA WhatsApp REST API. It's especially useful for DevOps, sysadmins, or teams who need real-time server alerts delivered via WhatsApp. ⚙️ Setup Instructions Set up HetrixTools: Create a HetrixTools account at https://hetrixtools.com/register Create your Uptime Monitors and/or enable Resource Usage Monitoring for your servers. Go to your HetrixTools contact settings and add the n8n Webhook URL provided by the workflow. Make sure to select this contact in your monitor’s alert settings. Configure n8n Webhook: Set the Webhook node to HTTP method: POST Ensure it is accessible via a public URL (you can use n8n Cloud, reverse proxy, or tunnel like ngrok for testing). Customize WhatsApp Message: The workflow includes a conditional branch to check whether the event is a Resource Usage alert or an Uptime alert. Each branch contains editable text nodes for customizing the WhatsApp message content. Set up GOWA WhatsApp API: Make sure your GOWA instance is running and accessible. Create necessary credentials (API key, base URL, etc.). In n8n, add the credentials and fill in the sendChatPresence and sendText nodes accordingly. Deploy the Workflow: Save and activate the workflow. Trigger a test alert from HetrixTools to verify if messages are received on WhatsApp. 🧱 Prerequisites An active HetrixTools account with Uptime Monitors or Resource Usage Monitoring enabled. A publicly accessible instance of n8n with Webhook node enabled. Access to a running and configured GOWA (WhatsApp REST API) server. Required credentials configured in n8n for GOWA (API key, URL, phone number, etc.). An n8n automation workflow template by Syamsul Bahri.
