Install dependencies

You can use the built-in `https` module or a library like `node-fetch` or `axios`. The example below uses `node-fetch` for readability.

Install node-fetch

npm install node-fetch@2

Send a batch of logs

This example sends two log entries to the IngestAPI with a shared source and entity.

Node.js logging example

const fetch = require('node-fetch');

async function sendLogs() {
  const payload = {
    source: "checkout-service",
    entity: {
      name: "checkout-service",
      kind: "service",
      tags: ["prod", "payments"]
    },
    logs: [
      {
        timestamp: new Date().toISOString(),
        level: "error",
        message: "Payment gateway timeout",
        requestId: "req-" + Date.now(),
        region: "us-east-1"
      }
    ]
  };

  const res = await fetch("https://ingest.techguys2go.com/v1/logs", {
    method: "POST",
    headers: {
      "X-TG2G-Api-Key": process.env.TG2G_INGEST_KEY,
      "Content-Type": "application/json"
    },
    body: JSON.stringify(payload)
  });

  if (!res.ok) {
    console.error("Failed to send logs:", res.status, await res.text());
  }
}

sendLogs().catch(console.error);
