🔢 Character Limit

  • Minimum: 1 character
  • Maximum (technical): 512 characters
  • Best practice: Keep names under 50 characters for readability and easier management.

❌ Invalid Characters

Template names cannot include:

  • Spaces → order confirmation 🚫
  • Special characters → order#update, order@2024 🚫
  • Uppercase letters → OrderUpdate 🚫

✅ Valid Format

  • Use only lowercase letters, numbers, and underscores.
  • Must be unique across your WhatsApp Business Account.

🛠️ What Happens If You Violate the Rules?

  • ⚠️ MyOperator will show an error message at submission.
  • 🔄 You’ll need to rename and re-submit following the correct format.

🌟 Best Practices for Naming Templates

  • Keep names short and descriptive (under 50 characters).
  • Use prefixes by use case for easier management:
    • order_update_2024
    • promo_summer_sale
    • otp_login_flow
  • Avoid generic names like template1 — they make it harder to track usage later.
