10 Golden Rules to Protect Your WhatsApp API Number
1️⃣ The Golden Rule: Only Message People Who WANT You ❤️
Imagine you walk into someone’s home uninvited… awkward, right? That’s what happens when you message people without permission.
Always get opt-in consent → online form, QR scan, checkout checkbox, or a “Reply YES” flow.
✅ Good Example: “Hi Riya, thanks for signing up! We’ll send you order updates and special offers on WhatsApp. Reply STOP anytime.”
❌ Bad Example: Sending a promo to a random list you bought. (Spam alert 🚨 = block + report = danger for your API).
Why this protects your number → Meta loves when users expect your messages. Zero surprises = zero complaints.
2️⃣ Play by the 24-Hour Rule ⏳
If a customer messages you, you’ve got a 24-hour magic window to reply with anything (free chat).
After 24 hours? Use an approved template only.
✅ Example: Customer says “Where’s my order?” → reply anytime in 24 hrs. ❌ Example: Sending them a discount message 2 days later without a template.
Why this protects your number → keeps you in Meta’s “green zone” and avoids penalties.
3️⃣ Templates: Dress Right for the Occasion 👗👔
Every template has a category → Utility, Marketing, or Authentication. Pick the right outfit for the right party.
Utility → service updates (“Your order is shipped”)
Marketing → promos & offers (“20% off today”)
Authentication → OTPs (“Your code is 54321”)
✅ Good: “Hi Aditi, your appointment is confirmed for 4 PM.” (Utility)
❌ Bad: “Hi Aditi, your appointment is confirmed. Also, here’s 20% off hair spa!” (Mixed up! Should be Marketing, not Utility).
Why this protects your number → No template mix-ups = no Meta red flags.
4️⃣ Stop Cold Broadcasting 🥶 → Start Warm Conversations 🔥
Cold blasting = 🚫. Warm, targeted audiences = ❤️.
Use Custom Audiences → past buyers, recent leads.
Use Lookalikes → people who resemble your best customers.
Retarget people who clicked your ads → they already showed interest.
✅ Good: Send “Thanks for shopping last month, here’s early access to our festive sale.” ❌ Bad: Blast 20,000 random numbers with “BIG SALE TODAY!!!”
Why this protects your number → Warm = fewer complaints, more replies. Cold = high spam reports → restriction risk.
5️⃣ Spice Up Your Messages 🌶️ (Content that Clicks)
Keep it short, friendly, personal.
Add value: updates, reminders, guides, deals.
Use media: 📸 images, 🎥 videos, 📄 PDFs, 🎯 CTA buttons.
✅ Good: “Hi Aarav! Your AC service is booked for 12 Sep. Tech: Raju (📞 9xxx). Tap below to confirm 👇 [Confirm Booking]”
❌ Bad: “AC SERVICE DISCOUNT. CALL NOW!!!”
Why this protects your number → Fun, helpful messages = happy customers = positive engagement = Meta loves you.
6️⃣ Don’t Be Pushy 🚦 (Cadence & Frequency)
1-2 messages a day is more than enough.
Give space → follow-up after 24–72 hours if no reply.
Ramp campaigns slowly: 100 → 500 → 2000 (test engagement before scaling).
✅ Smart Flow: Day 1: Order update Day 3: Feedback request Day 7: Personalized offer
❌ Spam Flow: 3 promos in 1 day → instant blocks.
Why this protects your number → Prevents the dreaded “131056 error” (too many messages too fast).
7️⃣ Always Offer a Way Out 🏃♂️
Let users unsubscribe anytime. Simple “STOP” is enough.
✅ Good: “Reply STOP to unsubscribe. You won’t hear from us again (promise 🤞).” ❌ Bad: Keep messaging even when someone says “I don’t want updates.”
Why this protects your number → Users feel in control = fewer complaints. Meta notices when you ignore opt-outs (big danger).
8️⃣ Track Your Health 🩺
Check your Account Quality in Facebook Business Manager: Green ✅, Yellow ⚠️, Red ❌.
Also monitor:
Block rate → keep Quality rate high
Opt-out rate → keep low
Response rate → higher = better
Template approvals → if rejections pile up, rethink your wording
Why this protects your number → Early signs help you fix before Meta steps in.
🔍 How to Check Your Block Rate & Number Health in FBM
You can monitor your WhatsApp Business API number’s health directly inside Meta Business Manager (FBM). Here’s how:
🛠 Step-by-Step Guide
Login to FBM Go to Meta Business Manager and sign in with your admin account.

Navigate to WhatsApp Accounts
Go to Accounts → WhatsApp Accounts.
Select your WhatsApp Business Account (WABA).

Review Number Health Here you’ll see:
Messaging Tier → Shows how many unique users you can reach per day (1K, 10K, 100K, unlimited).
Quality Rating →
🟢 High (Green): Your messages are well received.
🟡 Medium (Yellow): Some users are blocking you, needs improvement.
🔴 Low (Red): Too many blocks or negative feedback. Immediate action needed.

Block rate is simply how many users are blocking your number after receiving your messages.
If too many people block → your quality rating drops.
If rating stays Low → Meta may restrict your number.
