Prompt copied, paste it into the chat (Ctrl/Cmd + V).

You are an expert in WhatsApp message templates. Review and fix the template below so it passes Meta's approval.

Meta's rules: body max 1024 characters, header and footer 60 each, button text 25. Variables in double-curly-brace format, sequential from 1 with no gaps, never adjacent, never at the start or end without text. Utility templates without promotional language. Auth templates without links, media or emojis.

Return the corrected template plus the ready-to-use JSON for the Cloud API endpoint POST /message_templates.

No rule-based issues found. Review tone and clarity.

Three steps to a submission-ready template.

Pick a category, then add a header, body with variables, footer and buttons.

The preview shows the real WhatsApp view; the checker flags every rule-based rejection reason.

Copy the API JSON, submit it in SendSeven and send the template within minutes.

Rule-clean templates clear Meta in minutes. Each mistake costs a fix-and-resubmit cycle, or bumps you into slow manual review.

Export the exact payload for the Cloud API endpoint, with no manual work.

WhatsApp template categories: Marketing, Utility, Authentication

Every WhatsApp message template belongs to exactly one of three categories. The choice decides what's allowed and what Meta charges per message.

Promotions, offers, product news and re-engagement. Highest per-message price and an opt-out requirement. Promotional content always belongs here.

Transactional and service updates after a customer action, such as order or shipping confirmations. Notably cheaper than marketing.

One-time verification codes. No links, media or emojis, and parameters capped at 15 characters.

Most rejections have formal, rule-based causes you can avoid before submitting. These are exactly what the generator validates live:

Wrong variable format or gaps in the placeholder numbering

Two variables next to each other, or a variable at the very start or end of the body

A missing sample value for a placeholder

Body over 1,024 characters, or a header/footer that's too long

Promotional language in a Utility template, which forces the pricier Marketing reclassification

A link shortener instead of a branded domain

Links, media or emojis inside an Authentication template

Content judgments such as spam suspicion, brand impersonation or quality are decided by Meta's reviewers. For those, the tool gives an AI risk assessment rather than a guarantee.

WhatsApp sets fixed limits per template element. Staying within them keeps you in the fast automated review and out of slow manual checks.

Character and count limits for each WhatsApp message template element, from body text and header to buttons.

Text formatting: asterisks for *bold*, underscores for _italic_, tildes for ~strikethrough~ and triple backticks for monospace. The live preview shows the result instantly.
