Compliance Guide: Handling Opt-outs and DND in WhatsApp
By 5MinutesAPI Support•
The Importance of Compliance
Unlike email, where spam filters hide junk, WhatsApp is an intimate space. If you annoy a user, they will press the "Block and Report" button. If your block rate exceeds a tiny threshold, Meta will throttle or permanently ban your WABA number.Automating the "STOP" Command
Always include a Quick Reply button labeled "Opt-out" or "Stop Promotions" in your marketing templates. When a user clicks it, 5MinutesAPI instantly routes that webhook back to your server.
Your backend must immediately update the user's profile in your database to whatsapp_opt_in = false. Any future marketing loops must filter out these users.
The Auto-Refund Safety Net
If you accidentally message a user who has blocked your number, Meta will reject the payload. 5MinutesAPI's Golang engine detects this failure in real-time and automatically refunds the message cost to your wallet, protecting both your compliance score and your budget.
