WhatsApp Message Templates: How to Write Them and Get Meta Approval

WhatsApp message templates (also known as Highly Structured Messages or HSMs) are pre-approved formats businesses must use to send outbound notifications to customers outside the standard 24-hour service window.

Whether you want to send booking confirmations, appointment reminders, or order receipts, your templates must be approved by Meta's review systems. Here is how to submit templates that pass review on the first try.

The 3 Official Template Categories

Meta categorizes templates strictly. Selecting the wrong category is the most frequent reason for rejections:

• Utility Templates: Confirmations, appointment reminders, order receipts, and status updates directly requested by the customer. Easiest to get approved.
• Authentication Templates: One-time passwords (OTPs) and security verification codes for user logins.
• Marketing Templates: Promotional updates, discounts, product announcements, and re-engagement campaigns.

Best Practices to Prevent Meta Rejections

Following simple formatting standards ensures fast approval times (often under five minutes):

• Use Clear Variable Placeholders: Number variables sequentially (e.g., {{1}}, {{2}}) and provide realistic sample values during submission.
• Avoid Overly Promotional Language in Utility Templates: Mixing discount codes or marketing hooks into an appointment reminder triggers immediate category rejection.
• Clear Opt-Out Information: Marketing messages should include straightforward unsubscribe language or footer buttons.
• Flawless Grammar and Punctuation: Automated Meta filters reject templates with spelling errors or excessive capitalization.
