The Header dropdown also offers a Text header. This guide covers the media header types — Image, Video, and Document. For the full template walkthrough, see How to Create a Message Template Campaign for WhatsApp API.
Step 1: Open the template builder
Go to the bitCRM Template dashboard, click Create new template, and select Campaign.
Choose between WhatsApp Business App or WhatsApp Cloud API.
Step 2: Complete Template setup
In the first step of the wizard, fill in your Template name, Languages, Message category, and Template type, then click Next to move to Message content.
The header is available on Standard templates. It is hidden on Carousel and Catalog templates, in line with Meta’s WhatsApp Business API policy.
Step 3: Choose a media header type
In the Message content step, open the Header dropdown and choose the media type you want:| Header type | Supported format |
|---|---|
| Image | JPEG or PNG |
| Video | MP4 |
| Document |

Step 4: Upload your media
After selecting a media type, a file drop container appears. Upload your file. The builder checks that the file matches the supported format and size limit for that header type before accepting it.
Each media type has a maximum file size. For the current format and size limits, see the header-type table in How to Create a Message Template Campaign for WhatsApp API. If your file is the wrong format or too large, the builder shows an error so you can replace it.
Step 5: Preview and submit
Preview your message on the right sidebar to confirm the media displays as expected, then click Save template to submit it to Meta for review.
