For the API

This builder doesn't submit anything to Meta — paste the text into WhatsApp Manager, or send the JSON to the Graph API yourself.

How to Use Template Builder

01

Draft your template

Select a category and language, then write your message header, body text with variables, footer, and action buttons.

02

Verify validation checks

Ensure all validation checks turn green before submitting. Provide realistic sample values for each variable used in your message.

03

Submit for approval

Copy and paste your finalized template into WhatsApp Manager, or send the generated JSON payload directly to Meta’s Graph API.

What is a WhatsApp Business Template?

When using the WhatsApp Business API, you can respond to customer messages freely within a 24-hour service window. To initiate a conversation or contact customers outside this window, Meta requires you to send a pre-approved message template.

Templates are divided into three core categories:

Marketing: Promotional offers, product updates, and cart reminders.
Utility: Transactional updates, order confirmations, shipping details, or billing receipts.
Authentication: One-time passcodes (OTPs) with fixed security text mandated by Meta.

Practices for Approval

Select the correct category: Avoid embedding discounts or promotional phrases into utility templates, as Meta will reclassify them to marketing.
Provide clear text context around variables: Use structured text around variables (e.g., "Hi {{1}}, your order {{2}} is on its way!"). Avoid messages that consist mostly of variables.
Include realistic sample data: Reviewers check your sample values to understand the message context. Use realistic example text rather than filler characters.
Position variables properly: Ensure variables are not placed at the very start or end of the message body.
Include opt-out options: Adding a simple opt-out footer (e.g., “Reply STOP to unsubscribe”) helps speed up approval for marketing communications.

Frequently Asked Questions

Does this builder submit the template directly to Meta?

No. This tool formats and validates your template code. You can copy the result into Meta WhatsApp Manager or send the JSON file via the WhatsApp Graph API.

How long does Meta take to review templates?

Most templates receive approval within a few minutes, though some reviews may take up to 24 hours. You can track approval status inside WhatsApp Manager or via API webhooks.

What are the character limits for templates?

Message Body: Up to 1,024 characters

Header & Footer: Up to 60 characters each

Button Labels: Up to 25 characters per button (maximum 10 buttons total, with up to 2 website URL buttons)

Can I use named variables like {{name}} instead of numbers?

Meta supports named variables via the API. This tool uses numbered parameters ({{1}}, {{2}}), which are universally supported across both the API and WhatsApp Manager interface.

Can I create and dispatch templates using AI?

Yes. Through WhatSync Business, you can link your Business API account to ChatGPT or Claude to draft, submit, and trigger approved templates automatically.
