Question
I'm using AI agents in messaging (Legacy) to create an AI agent for WhatsApp. Is there a character limit for AI agent messages in the Present options step with WhatsApp?
Answer
Yes. For AI agents in messaging (Legacy), the options in the Present options step on social messaging channels such as WhatsApp are limited to a maximum of 20 characters each. While general messaging text bodies can support up to 4,095 characters, option labels exceeding the 20-character limit will fail or degrade. If your options require more detail, keep the option label concise (under 20 characters) and include the detailed text in a preceding Send message step or link to a Knowledge article.
