How to Send WhatsApp Messages & Actions with Wawp and n8n

The power of Wawp lies in its ability to automate your WhatsApp communication. This is done through the Wawp Main Action node in n8n, which allows you to send various messages and control your connected WhatsApp number.

Understanding the Wawp Main Action Node

The Wawp Main Action node is your primary tool for sending all types of messages and commands. It is designed to be a single, powerful node with multiple capabilities.

The node’s functionality is organized into two main fields, as seen in the screenshot:

• Category: This field defines the type of action you want to perform (e.g., Send Message, Chats, Presence).
• Operation: This field specifies the exact action within the selected category (e.g., Send Text, Start Typing, Get Chat Info).

By selecting a Category and an Operation, you can access a wide range of powerful functions.

Key WhatsApp Actions You Can Send

The Wawp Main Action node gives you the ability to manage your WhatsApp account from within your n8n workflows. Below are some of the most common categories and operations you can use.

Sending Messages

This is the most common use case. The Send Message category allows you to send various message types to any phone number.

• Send Text: Send a simple text message.
• Send Media: Send images, videos, or documents by providing a media URL.
• Send Buttons/Polls: Send interactive messages to engage your audience.

Presence & Chat Control

You can control your account’s status and manage individual chats to create a more responsive user experience.

• Set Presence: Set your status to typing or recording before sending a long message.
• Mark as Seen: Mark incoming messages as read to show the blue checkmarks.
• Star Message: Mark a specific message to find it easily later.
• Archive Chat: Archive a conversation to clean up your chat list.

Profile & Account Management

The node also allows you to control key aspects of your account and manage contacts.

• Get Profile Info: Retrieve a contact’s profile picture or “About” message.
• Set Profile Info: Change your own profile information directly from a workflow.
• Block/Unblock Contact: Control who can send you messages.

📦 Successful Message Response (n8n JSON Output)

When the Wawp Main Action node successfully dispatches a text or media message, it returns a structured JSON response payload. You can capture and map this output in downstream nodes to log the message ID in your CRM database or record it inside Google Sheets to audit the delivery pipeline:

💡 Professional Automation Best Practices:

• Simulate Human Interaction: Before calling the Send Text action to reply, prepend a Set Presence node and set your session presence status to typing for 2 to 5 seconds. This adds a realistic human delay to the conversational workflow.
• Pre-Flight Contact Auditing: To prevent messages from getting bounced by invalid entries, use the Contacts category and invoke the Check Phone Exists operation beforehand to safely filter active WhatsApp accounts.

Explore More Actions

The Wawp Main Action node supports a wide range of other categories, including Groups, Contacts, and 24 Hour Status. Each of these contains multiple operations that you can use to build custom automations.
