How to use it

3 steps, under a minute.

  1. 1Pick a category

    Choose Marketing, Utility or Authentication and add an optional header.

  2. 2Write body and buttons

    Type the body with {{1}}-style variables, add sample values, a footer and up to three buttons.

  3. 3Fix the warnings

    Read the approval tips and fix anything flagged before submitting to Meta.

The short answer.

The WhatsApp Template Previewer shows a message template (header, body with {{1}} variables, footer and buttons) inside a realistic phone chat, and lints it against the most common reasons Meta rejects templates, such as variable formatting, length and promotional wording in utility templates.

Why preview before you submit

Every business-initiated WhatsApp message must use a template approved by Meta. Rejections cost you days, usually because of avoidable issues: variables at the very start or end of the body, variables placed side by side, a missing sample value, a body over 1,024 characters, or salesy wording in a template filed as Utility. Previewing helps you catch these first and see how line breaks and buttons really render on a phone.

Marketing vs utility vs authentication

Marketing templates promote offers, utility templates confirm something the customer asked for (an order update or appointment reminder), and authentication templates carry one-time passwords. Meta charges each category differently, so choosing the right one matters for your costs as well as your approval chances.

Questions

WhatsApp Template Previewer, answered.

Does this submit my template to Meta?

No. It's a preview and linting tool. You submit templates from your WhatsApp Business API dashboard, such as RapBooster's.

What is the body character limit?

The template body can be up to 1,024 characters. The header text is limited to 60 and the footer to 60.

How many buttons can a template have?

Quick-reply and call-to-action buttons have limits set by Meta. Keep to three or fewer for a clean layout; this previewer supports up to three.

Are the lint rules official?

They are based on Meta's published guidelines and common rejection reasons as of Sept 2026. Meta has the final word.
