Can Vercel Cron send Google Analytics reports?

Yes. Vercel Cron can request a protected API route that fetches GA4 data and sends a Telegram report.

How should the Vercel Cron route be protected?

Use a long CRON_SECRET and require the secret through a query parameter or Authorization bearer token.

GA4 Vercel Cron Report

Create the API route

The Vercel adapter wraps runDailySummary() and handles request authorization, dry runs, site selection, and JSON responses.

api/daily-summary.js Vercel

const {
  createVercelDailySummaryHandler,
  ga4Source,
  telegramDestination
} = require("web-analytics-reporter");

module.exports = createVercelDailySummaryHandler({
  secret: process.env.CRON_SECRET,
  source: ga4Source({
    clientEmail: process.env.GOOGLE_CLIENT_EMAIL,
    privateKey: process.env.GOOGLE_PRIVATE_KEY
  }),
  destination: telegramDestination({
    botToken: process.env.TELEGRAM_BOT_TOKEN
  }),
  sites: [{
    id: "marketing",
    name: "Marketing Site",
    ga4PropertyId: process.env.GA4_PROPERTY_ID,
    telegramChatId: process.env.TELEGRAM_CHAT_ID
  }]
});

Add the Vercel Cron schedule

vercel.json JSON

{
  "crons": [
    {
      "path": "/api/daily-summary",
      "schedule": "0 8 * * *"
    }
  ]
}

Test the route

Preview the report without sending Telegram by opening the route with dryRun=1. Send a real report only after the message looks right.

dry run URL

https://example.com/api/daily-summary?secret=<CRON_SECRET>&dryRun=1

Use the initializer

The CLI can create the starter Vercel route, vercel.json, and .env.example for you.

terminal npx

npx web-analytics-reporter init --site-name "Marketing Site"
