How to Send WhatsApp Messages Automatically Using n8n and CRM Messaging

Most CRMs and platforms today still don’t provide native WhatsApp support—especially when it comes to automated conversations and customized workflows. That’s where n8n and CRM Messaging together become a game-changer.

With CRM Messaging as your WhatsApp backend and n8n as your automation engine, you can connect ANY CRM, Google Sheets, form builder, or app to send automated, personalized WhatsApp messages—without writing a single line of code.

Why Use n8n with CRM Messaging (When You’re Using Another CRM)

If you are using CRM such as Hubspot, Zoho or Salesforce we have native integration

But if your CRM doesn’t support native WhatsApp workflows—or you’re tired of paying extra for basic automation—this setup gives you:

• 🌐 Integration with any CRM or platform (Lemlist, Pabbly, Airtable, Notion, Typeform, etc.)
• 📲 Automated WhatsApp messaging for leads, customers, or subscribers
• 💬 Triggered messages based on CRM actions (e.g., form filled, contact created, tag added)
• 🧠 Personalization powered by variables like name, product, service, etc.
• 💥 No platform lock-in—you control the flow using n8n

How the System Works

Your CRM or App → Webhook/API → n8n Workflow → CRM Messaging API → WhatsApp Sent ✅

Think of CRM Messaging as your WhatsApp gateway, and n8n as your workflow builder. No need to replace your current CRM. You just extend its power.

Step-by-Step Setup Guide

To use CRM Messaging inside your n8n workflows, you need:

• API Token
  Go to your CRM Messaging Developer Console, copy the API token
• n8n account (self-hosted or cloud)

📨 New Incoming Message Trigger

You can listen for incoming messages using the Webhook Node in n8n.

Steps:

1. Drag the Webhook Node into your n8n workflow.
2. Set:
   • Method: POST
   • Path: incoming-message (or any custom name)
3. Copy the Production Webhook URL and go to CRM Messaging > Developer > Webhooks.
4. Paste the URL in incoming and save.

✅ Now, when a message is received on your number, it will be pushed to this workflow in n8n.

📤 Send SMS / WhatsApp Action

The Send SMS / WhatsApp step allows you to send messages through CRM Messaging directly from n8n.

To use:

1. Add an HTTP Request Node in n8n after your trigger.
2. Choose:
   • Method: POST
   • URL: https://app.crm-messaging.cloud/index.php/Api/sendMsg
3. Use a Bearer Token authentication:
   • Add your CRM Messaging API Token in credentials
4. Send the following formdata in the body:
   • to = {{ $json.body.from }} or use any other reference for to number
   • msg = your sms content
   • fromnum = {{ $json.body.to }} or use your other from number

Additionally, if your message has media attachments or is multilingual or your account has multiple phone numbers and channels then pass these additional optional parameters in form data in the API call

mediaUrl
fromnum
channel
lang

Here mediaUrl is the media attachment link

fromnum is from a phone number, it can be a WhatsApp phone number id in the case of WhatsApp or Long Code for SMS

channel is either whatsapp or SMS

lang is as per language saved in the template, you can find this code in template manager Text Messaging for Marketers and Sales Reps – CRM Messaging (crm-messaging.cloud) for eg. Pass en_US for English(US)
