Interactive list block

WhatsApp interactive list message — best when the customer needs to choose from more than 3 options.

Config

• Body text — required, max 4096 chars
• Header / Footer — optional text
• Button text — what the customer taps to open the list (max 20 chars, default “Choose”)
• Sections — at least 1, each with:
  • Title — section header inside the list
  • Rows — up to 10 per list across all sections. Each row has a title (24 chars)
    • optional description (72 chars)

Behaviour

• Sends as interactive { type: "list" } to Meta
• The flow parks until the customer picks a row
• Each row has its own socket on the canvas — wire each to its downstream step
• 24-hour window applies
