How to Connect Square to WhatsApp with DMHub

Most Square merchants handle transactions in one system and customer communication in another. That disconnect means missed follow-ups, manual receipt sharing, and zero post-purchase engagement. Connecting Square to WhatsApp through DMHub closes that gap in about 15 minutes.

This guide walks through the full setup, from API credentials to your first automated message.

Why Connect Square to WhatsApp?

Square processes payments. WhatsApp is where your customers actually are. When the two talk to each other, you unlock workflows that neither can do alone:

• Automatic order confirmations sent via WhatsApp the moment a Square transaction completes
• Digital receipts delivered to customers' phones without asking for email
• Post-purchase follow-ups triggered by purchase amount, frequency, or product category
• Loyalty point notifications synced with your Square loyalty program
• Review requests sent 2 hours after purchase

For businesses in Latin America, the Middle East, and Southeast Asia, WhatsApp isn't optional. It's the primary communication channel for 2 billion people, and Square's expanding global footprint makes this combination increasingly powerful.

What You Need

1. A Square account with API access (free on all Square plans)
2. A DMHub account with an active WhatsApp Business number
3. About 15 minutes

Step-by-Step Setup

Step 1: Get Your Square API Credentials

1. Log into your Square Developer Dashboard
2. Create a new application or select an existing one
3. Copy your Access Token from the Credentials tab
4. Note your Location ID from the Locations section

Step 2: Connect Square in DMHub

1. Navigate to Settings > Integrations in your DMHub dashboard
2. Find Square in the integration directory and click Connect
3. Paste your Access Token and Location ID
4. Click Test Connection to verify everything works
5. Select which data to sync: orders, customers, inventory, or all three

Step 3: Configure WhatsApp Automations

With the connection live, set up your first automations:

1. Go to Automations > New Automation
2. Select Square Order Completed as the trigger
3. Choose your WhatsApp message template (order confirmation, receipt, or custom)
4. Set conditions if needed (e.g., only for orders over $25, or only for new customers)
5. Activate the automation

Step 4: Map Customer Data

DMHub automatically matches Square customers to WhatsApp contacts using phone numbers. For customers without a phone number in Square, you can:

• Add a QR code at your counter that links to WhatsApp
• Ask for WhatsApp number at checkout
• Use DMHub's web widget to capture contacts on your website

Global Use Cases

Coffee shop in Dubai: Every transaction triggers a WhatsApp receipt with loyalty points balance. Customers reply to reorder their usual.

Boutique in Sao Paulo: Purchase confirmations include a WhatsApp link to the product care guide. Returns dropped 18% in the first month.

Restaurant in Manila: Square POS syncs daily revenue to the owner's WhatsApp dashboard summary every evening at 10 PM.

Retail store in Lagos: End-of-day sales reports sent to the owner via WhatsApp, with low-stock alerts for items that need reordering.

Testing Your Setup

Send a test transaction through Square and verify:

1. The order appears in DMHub's activity feed within 30 seconds
2. The WhatsApp confirmation message is delivered to the customer
3. Customer data syncs correctly (name, phone, purchase history)

If messages aren't sending, check that your WhatsApp template has been approved by Meta and that the customer's phone number is in E.164 format.

Getting Started

Connecting Square to WhatsApp turns every transaction into the start of a conversation. Your POS data powers your messaging, and your messaging drives repeat purchases. It's a loop that compounds over time.
