WhatsApp UI Validation to Enforce 24-Hour Messaging Limits

/in

We’ve introduced a UI validation that automatically checks your 24-hour messaging limit per phone number, preventing you from exceeding Meta’s allowed thresholds. This helps you avoid hitting Tier-based limits (1,000 messages/24 hours) and significantly reduces the risk of account bans or phone number being flagged

✔️ Acceptance Criteria

🚫 Example Error Message

Messaging Limit Exceeded!

We’re sorry, but you cannot send WhatsApp bulk messages to 344,611 contacts. Your current messaging limit is 1,000 customers per 24 hours.

To increase your messaging limit, initiate conversations with at least 500 unique customers over a 7-day rolling period.

ℹ️ What Are Messaging Limits?

Messaging limits determine how many business-initiated conversations you can start in a 24-hour rolling window. A “business-initiated conversation” occurs when you send a WhatsApp user a marketing, utility, or authentication template for the first time in that 24-hour period.

Initial Limit: Most new business phone numbers can initially send up to 250 business-initiated conversations within 24 hours.

Tier Increases: Over time (and based on your account quality), this limit can be raised to:

  1. 1K (1,000)
  2. 10K (10,000)
  3. 100K (100,000)
  4. Unlimited

❓ How Do I Increase My Limit?

You can self-upgrade from 250 to 1K conversations per 24 hours by completing business verification. Submit your business for business verification. If your business is approved, we will analyze your messaging quality to determine if your messaging activity warrants an increase to your messaging limit. Based on this analysis, we will then either approve or deny a messaging limit increase.

Automatic Scaling beyond 1K happens when your phone number consistently remains connected and maintains a high quality rating.

If your phone number’s quality rating is low, Meta may retain the 250 limit until the quality improves.
