Summary

Send an interactive WhatsApp message from a connected WABA number to a recipient, using a URL button, quick-reply buttons, or a selectable list. The node posts the message to 2Chat’s WABA send-message endpoint.

Inputs

  • WABA Number Name or ID (required) — Select a WABA number connected to 2Chat, or provide its ID.
  • To Number (required) — Recipient phone number.
  • Interactive Type (required) — Choose a call-to-action URL button, reply buttons, or a list message.
  • Body Text (required) — Main message text.
  • Header Text — Optional text above the body.
  • Footer Text — Optional text below the body.
  • Button Display Text (required) — For a URL button, the text shown on the button.
  • Button URL (required) — For a URL button, the link opened when tapped.
  • Buttons (required) — For reply buttons, provide 1–3 buttons, each with an ID and title. The ID is returned in the reply webhook; titles are limited to 20 characters.
  • List Button Text (required) — For a list message, the text on the button that opens the list.
  • Sections (required) — For a list message, provide at least one section with rows. Each row has an ID, title (up to 24 characters), and optional description (up to 72 characters). Provide no more than 10 rows total; each section needs a title when there is more than one section. Row IDs are returned in the reply webhook.

The operation returns the response through n8n’s JSON-array helper. Validation errors are raised if a reply-button message has no buttons or more than three, or if a list has no sections, no rows, more than ten rows, or multiple sections with a missing title.
