The character count limit for a message on the WhatsApp Federation channel is 4096 characters. This limit is imposed by the WhatsApp Business API used for Sending Text Messages as explained here.
Sending a message containing more than 4096 characters will cause the following error.
Notes:
- The character count includes the display name and colon, so slightly fewer than 4096 characters are available for a message.
- Line breaks and items formatted with bold and italics also use up character space.
