# What types of headers can I use in a WhatsApp template?

|| Info
A WhatsApp template supports one optional header that appears at the top of your message. You can choose only one type per template (Text, Image, Video, or Document) — or no header at all. Different header types cannot be combined. Headers help grab attention or add media context, but they must follow Meta’s format and size guidelines.

## 1. Text Header

* Limit: Max 60 characters
* Best for: Short static titles like “Order Confirmation” or “New Offer”
* Restrictions: Only 1 variable `{{ }}` allowed in Text option.
* Correct Example:

```
Order Confirmation
```

Incorrect (dynamic, no longer supported):

```
Order #{{1}} has shipped!
```

## 2. Image Header

* Limit: Max 5MB
* Formats: JPEG, JPG, PNG

## Important Rules

* You can add only one header type (text, image, video, or document).
* The header is optional, but once added, it must meet format and size requirements.
* Meta will reject templates with unsupported formats, oversized files, or disallowed content.

| Tip
Use headers to highlight critical info visually (like an invoice PDF or promo banner), while keeping personalization in the body section of your template.
