flow sends a WhatsApp Flow built in WhatsApp Manager: the end user taps a button, fills in a form inside WhatsApp, and the fields come back to the agent as a message. WhatsApp only. The platform teaches this block on every channel except web and tells the model to use it only when it knows the channel is WhatsApp; instruct it explicitly with your Flow ID. See Response formatting.
Verified against lua-cli 3.33.0.
Syntax
Fields
Each field goes on its own line. Separators can be
= or :, with or without spaces or quotes; a block written on one line is dropped because the first field swallows the rest.
Example

A WhatsApp Flow: the message, the form, and the confirmation
Where it renders
Submitted data
When the end user submits, the agent receives a message of the formUser completed a WhatsApp Flow. Submitted data: followed by one - field: value line per field. Password fields are hidden in the WhatsApp chat but still arrive in that message and are stored in the conversation; for one-time codes, validate inside the flow with a data-exchange endpoint so only the result reaches the agent.
