Requirements for the content and format of VK messages
You can use 2 layouts for your message template:
- Text + Image
It is only necessary to agree on the text of the message.
The allowed length of a business message in VK is no more than 2048 characters, including emoji. You can attach up to 5 images to a message.
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.
Emoji messages cannot be registered in service and transaction messages. Emoji can only be used in promotional dispatch.
