🔔 Meta Ads Low Balance Alert – Auto Notification via WhatsApp or Email

Hello my loves! I’m Amanda... I created this workflow with care for marketing professionals and agencies who manage multiple Meta Ads (Facebook) accounts and want to track ad account balances automatically — no more logging in every day or risking campaigns stopping unexpectedly.

With this setup, n8n will check the balance of each account using the Meta API, compare it to a defined threshold, and if the balance is too low, it will automatically send a friendly alert via WhatsApp or email. It also logs everything neatly into a Google Sheet — so you always know where things stand.

✨ What this workflow does

- 🧾 Pulls balance data from Meta Ads accounts using the Facebook Graph API - 📉 Compares current balance with the minimum threshold set in a Google Sheet - 🚨 Sends low-balance alerts via WhatsApp (Evolution API) or Gmail - 🧠 Customizes alerts depending on payment type: Boleto or Credit Card - 📊 Updates the Google Sheet with new balance, check date, and status - 📆 Can run automatically every day or manually whenever you want
