PerplexityWhat you can put in the header
These are WhatsApp's own rules, and Lead Pattern supports the same options.
| Header type | File | Size limit | Good for |
|---|---|---|---|
| Image | JPG or PNG | 5 MB | New collection, festive offer, event poster |
| Video | MP4 (H.264 video, AAC sound) | 16 MB | Product demo, short launch video |
| Document | 100 MB | Brochure, price list, catalogue, invoice | |
| Text | Up to 60 characters, 1 variable | — | A short headline instead of media |
| Location | A map pin | — | Store or event address (utility and marketing templates) |
A template has one header. Under it: the body (up to 1,024 characters), an optional footer (up to 60) and up to 10 buttons.
Tips
- One picture per template. In Lead Pattern the header image, video or PDF comes from the template itself, so make a separate template for each new campaign picture.
- Keep videos short and small. Use MP4. A file well under 16 MB downloads quickly on mobile data.
- Make the picture readable on a phone: big text, one message, no tiny print.
- Add a button so people can act right away. Broadcast with buttons →
- Sending a PDF to one customer? Inside the 24-hour window you can just attach it in the inbox. Send an invoice on WhatsApp →
What it costs per message
A media header doesn't change the price. Meta charges by the template's category: about ₹0.86 for marketing and ₹0.115 for utility in India. Indicative Meta rates, excluding GST; Lead Pattern passes them through with zero markup.
