Why Integrate Busy ERP with WhatsApp?

Busy ERP is a powerful accounting and business management software. WhatsApp, on the other hand, is where your customers already are. When you connect the two, you can:

• Send automatic messages for invoices, payments, and stock alerts

• Improve communication speed with clients and vendors

• Reduce manual effort and errors

• Keep your team and customers updated in real time

Step 1: Get Your FastWASMS.in Account

Go to FastWASMS.in and create an account. Once you log in, you’ll get two key details:

• Instance ID

• Access Token

You’ll need these for your API configuration.

Step 2: API URL Format

Here’s the format you’ll use to send WhatsApp messages directly from Busy ERP using FastWASMS.in:

Let’s break that down:

• [TONUMBER] → Recipient’s WhatsApp number (with country code, no + sign)

• [MSGTEXT] → Your message text

• instance_id → Your unique instance ID from FastWASMS

• access_token → Your API access token

Example:

You can test this link in your browser or from a script to confirm the message is sent successfully.

Step 3: Add It to Busy ERP

In Busy ERP, you can automate WhatsApp messages through its SMS/Email configuration or custom script setup (depending on your version).

You simply need to:

1. Open Configuration → Messaging or Alerts

2. Select HTTP API as the sending method

3. Paste the FastWASMS API URL (replace placeholders with field variables)

4. Test the setup

Once configured, Busy ERP will automatically trigger WhatsApp messages when an event occurs (like an invoice is created or a payment is received).

Step 4: Automate Common Messages

You can use this integration for:

• Invoice notifications

• Payment reminders

• Stock alerts

• Order confirmations

• Customer greetings

Just update the [MSGTEXT] parameter as needed.

Wrapping Up

That’s it. Your Busy ERP is now connected to WhatsApp using FastWASMS.in.
With this setup, your communication becomes faster, more reliable, and more personal — all without switching between apps.
