Shopify WhatsApp Integration: Sell and Support Through the UKs Favourite Messenger

Why WhatsApp Is the Marketing Channel UK Stores Are Underusing

WhatsApp has 2.4 billion global users and is the most used messaging app in the UK. Open rates for WhatsApp Business messages are 98%, compared to 20–30% for email. For direct-to-consumer Shopify brands, WhatsApp represents a high-engagement, low-competition channel that most competitors haven’t fully adopted yet.

This guide covers how to integrate WhatsApp with Shopify across customer service, marketing, and automated flows.

WhatsApp Business vs WhatsApp Business API

WhatsApp Business App (Free)

The free app for small businesses. Features: business profile, quick replies, automated greeting messages, product catalogue. Limitations: one user at a time, no bulk messaging, no API integration with Shopify. Suitable for stores receiving up to 20–30 WhatsApp conversations per day.

WhatsApp Business API (Paid, via BSPs)

The API version, accessed via WhatsApp’s Business Solution Providers (BSPs). Unlocks: multiple agents on one number, automated flows triggered by Shopify events, broadcast campaigns to opted-in subscribers, CRM integration. Accessed via platforms like Zoko, WATI, DelightChat, or Interakt.

Cost: BSP platform fee (£30–£150/month) + WhatsApp’s per-message fees (very low, around £0.01–0.05 per business-initiated message). For UK stores with significant customer volume, the API is worth it.

Click-to-Chat Button on Your Shopify Store

The simplest WhatsApp integration: add a floating “Chat on WhatsApp” button to your Shopify store that opens a WhatsApp conversation with your business number. Apps like WhatsApp Chat (many free options in App Store) add this in 5 minutes.

This converts customers with pre-purchase questions from email/contact form (slow) to WhatsApp (immediate). Response speed matters for conversion — a customer asking “does this come in large?” who gets an answer in 5 minutes on WhatsApp converts. One who waits 24 hours for an email reply usually doesn’t.

Automated WhatsApp Flows (API)

Via WhatsApp API platforms, Shopify events trigger automated WhatsApp messages:

• Order confirmation: “Hi [name], your order #[number] has been confirmed. We’ll notify you when it ships.”
• Shipping notification: “Your order is on the way! Track it here: [link]”
• Delivery confirmation: “Your order has been delivered. Let us know if everything looks perfect!”
• Abandoned cart: “You left [product] in your cart. Still interested? Here’s a 10% discount: [code]”
• Back-in-stock alert: “The [product] you were looking at is back in stock. Grab it here: [link]”
• Review request: “How’s your [product]? Leave a quick review and we’ll add 50 loyalty points to your account.”

WhatsApp Broadcast Campaigns

Via the API, send broadcast messages to opted-in subscribers for promotions, new product launches, and flash sales. WhatsApp broadcast rules:

• Only send to customers who have explicitly opted in to WhatsApp marketing (consent required)
• Use approved message templates for business-initiated messages
• Include a clear opt-out option
• Don’t send more than 1–2 promotional messages per week

Response rates on WhatsApp broadcast campaigns (when messages are relevant and non-spammy) are significantly higher than email — both because of the open rate and because replies happen in a conversational context.

WhatsApp for Customer Service

Integrating WhatsApp with a customer service platform (Gorgias, Zendesk, or a WhatsApp-native platform like WATI) allows your support team to handle WhatsApp messages alongside email and chat in a single inbox. This is critical for teams handling high message volumes — handling WhatsApp in the WhatsApp app itself is unscalable above 20–30 conversations/day.

UK consumers increasingly expect WhatsApp support as an option for higher-value purchases. Offering it — especially for premium or considered purchases — signals responsiveness and builds purchase confidence.
