Requirements for the content and format of WhatsApp messages
You can use 4 layouts for your message template:
- Text + button
- Text + image + button
It is only necessary to verify the text of the message.
WhatsApp allows you to send very long messages — up to 4096 characters in any language, including emoji.
When you add emoji to the text, remember that each emoji takes several characters. For example, a smiley is 8 characters long, a heart is 7 characters long, etc.
Important! Emoji messages cannot be registered in service and transaction messages. Emoji can only be used in promotional dispatch.
The maximum image size that you can use in a WhatsApp message is 1600x1200px, up to 2MB. The image can be uploaded from the device when creating the layout, or selected from the gallery of previously uploaded images.
Video materials requirements: file size up to 200 MB, 3gp, m4v, mov, mp4 format.
