Free tool
Message template checker
Catch the structural mistakes that get templates rejected before you submit — and see plainly which rules this tool does not verify.
Meta documents: lowercase letters, numbers and underscores, up to 512 characters.
Paste the body including its variables, for example {{1}} or {{first_name}}.
What we checked
Enter a template name or body to run the checks.
What this tool does NOT check
We only implement rules Meta states publicly. These are real requirements we cannot verify here, so we say so instead of guessing:
- Character limits for header, body, footer and button text — Meta does not state them on the page we cite.
- How many buttons a template may have, and which combinations are allowed.
- Whether your text matches the category (marketing / utility / authentication) you submit it under.
- Whether the content complies with the WhatsApp Business Messaging Policy — the most common reason for rejection.
- Whether a variable may open or close the body, or sit next to another variable.
- Media header requirements — format, size and the sample file you must upload.
The rules we check come from Meta's Message Templates documentation
This tool runs entirely in your browser. Nothing you type is sent to us or stored anywhere — this site has no form backend at all.
How to use it
