AI-generatedSummary
Sends a plain WhatsApp text message through the Wasup API, either from a chosen instance or from one Wasup auto-selects, with optional link preview and human-behavior options.
Inputs
- Auto-Select Instance — When on, posts to /api/send and Wasup picks a connected instance. When off, posts to /api/instances/{id}/send for the chosen instance.
- From Phone — Shown only with Auto-Select. Optional connected number to send from. Sent as from_phone when non-empty.
- Instance (required) — Shown only when Auto-Select is off. Pick from a searchable list or enter the instance ID (e.g. wa_lxyz123_abc45).
- To (required) — Recipient phone number with country code (no + or spaces), or a chat id.
- Message (required) — The text body to send.
- Link Preview — Whether to render a rich preview card when the text contains a URL. Defaults to true.
- Advanced Options — Collection with Typing Simulation (default true), Human Delay (default true), Skip Contact Save (default false) and Contact Name for auto-saving the recipient. Only the options you add are sent, with empty values dropped.
Output shape
One output item per input item, containing the JSON response from the Wasup send endpoint. If the response is an array, it is split into multiple items.
The send response includes a message_id, which the React and Get Status operations can use. With Continue On Fail enabled, a failed item returns {error: message} instead of stopping the workflow. API errors are raised as NodeApiError.
Examples
Example 1: Send an order confirmation from a specific WhatsApp number
Auto-Select off; Instance chosen from list; To = {{$json.phone}}; Message = 'Your order is confirmed'; Link Preview on.
Example 2: Send from any connected number without choosing an instance
Auto-Select on; optionally From Phone = 60123456789; To = recipient number; Message = text.
Example 3: Send a quick bulk-style notice without simulated typing delays
Instance set; To and Message set; Advanced Options: Typing Simulation off, Human Delay off, Skip Contact Save on.
