How to get WhatsApp templates approved first time
- Pick the right category. Order, shipping and payment updates are utility; anything with an offer or product suggestion is marketing. Meta re-categorises templates that mix the two.
- Give variables context. Write “Hi {{1}}, your order {{2}} has shipped” rather than “{{1}} {{2}}”. Never start or end the message with a variable.
- Add sample values. When you submit, give realistic examples for each variable so the reviewer understands the message.
- Keep it clear. Avoid ALL CAPS, lots of emoji, shortened links and vague wording like “click here”.
- Offer a way out. For marketing templates, a footer or quick reply such as “Stop promotions” reduces blocks, which protects your quality rating.

Frequently asked questions
What are the character limits for WhatsApp templates?
A text header can be up to 60 characters, the body up to 1,024 characters, the footer up to 60 characters, and each button label up to 25 characters.
Why does Meta reject WhatsApp templates?
The most common reasons are a variable at the very start or end of the message, variables next to each other or numbered out of order, too many variables for the amount of text, unclear or misleading wording, and promotional content in a template submitted as utility.
How do I make text bold or italic in WhatsApp?
Wrap text in asterisks for *bold*, underscores for _italic_, tildes for ~strikethrough~ and three backticks for ```monospace```. Templates support the same formatting.
Is my template text saved?
No. The preview runs entirely in your browser and nothing you type is sent to us.
