Design your Carousel WhatsApp message
1. In the Design step, you should select the pre-approved Carousel template in the template selection.
In the Design step, you can only use pre-approved templates you have applied for. While creating your templates, you can use media such as images, videos, documents, variables, emojis, and action buttons.
Using variables and emojis in templates is highly recommended since they help you make your content more friendly and, therefore, more personalized.
The media are useful for drawing users' attention. They can be personalized according to their attributes.
Using buttons will help you to engage with your users and target them more efficiently. For example, you can offer a discount coupon in the second message after the user chooses the positive reply in the first message.

When uploading videos, remember that changing a file’s extension to .mp4 does not convert it into an MP4 format. The video must be originally encoded in MP4; otherwise, it might fail the format check and result in an error. If your video is in a different format or exceeds the size limit, you must convert or resize it before uploading.
If the template includes a Call-to-Action (CTA) button, you can update the link.
