The character limit for a single text message in Meta's WhatsApp Business API is 4,096 characters. This limit applies to both regular text messages and message templates. While there is a higher overall limit for the total length of a message (including text, spaces, and special characters) of 65,536 characters, it's often recommended to stay within the 4,096 limit for optimal performance and user experience.
Here's a breakdown of character limits in the context of WhatsApp Business:
- Individual Text Messages: 4,096 characters.
- Template Headers: 60 characters, including the parameter name (e.g., {{1}}).
- Template Body: 1024 characters, including dynamic values.
- Template Footers: 60 characters.
- Interactive List Rows: 24 characters for the title and 72 characters for the description.
- Interactive Reply Buttons: 20 characters for the button label.
It's important to note that while the overall message limit is higher, exceeding the 4,096 character limit for a single message or the header/footer limits for templates can lead to issues with message delivery or rejection, according to Meta's documentation.
