  • Send Text Message — Send a text message to an active WhatsApp conversation within the 24-hour session window.

  • Send Button Message — Send a message that includes interactive buttons.

  • Send List Message — Send a message with a selectable list of options.

  • Get Messages — Retrieve messages from a conversation using the conversation ID.

  • Get Media file — Download a media file (such as an image, video, document, or audio file) using the file URL available in the incoming message’s data field, typically passed from the Wati Trigger output as {{ $json.data }}.

Template message operations

Use these operations to manage and send WhatsApp message templates.

Wati Triggers

The Wati Triggers allows your n8n workflow to start automatically when specific events occur.

  • To ensure the trigger works correctly, you must copy the webhook URL generated in n8n and add it in Wati: Connectors → Webhooks

  • If the webhook URL is not registered in Wati, the trigger will not receive any events and the workflow will not run.

Here's the list of available Wati triggers in n8n:

  • On all events — Fires the workflow whenever any supported activity or webhook event occurs within your Wati account.

  • On message received — Activates whenever any incoming WhatsApp message is received from a user.

  • On new contact message — Triggers specifically when a message is received from a phone number that is not already saved in your Wati contacts.

  • On session message sent — Fires when an outbound, free-form reply is successfully sent to a user within the active 24-hour customer service window.

  • On template message sent — Activates when a pre-approved, structured WhatsApp template message is successfully dispatched from your account.

  • On message delivered — Triggers when an outbound message successfully reaches the recipient's device (equivalent to two grey ticks).

  • On message read — Fires when the recipient actually opens and views your sent message (equivalent to two blue ticks).

  • On message replied — Activates when a contact uses the specific swipe-to-reply feature to respond directly to a previous message contextually.

  • On template message failed — Triggers if an attempt to send a template message encounters an error (e.g., invalid number, account restrictions) and cannot be sent.

These triggers enable real-time automation when customers send messages or when message delivery events occur.
