Setup Guide

How to connect Shopify Flow to WhatsApp API

Ensure Shopify Advanced or Plus plan

Shopify Flow is only available on Shopify Advanced (₹22,680/month) and Shopify Plus. If on Basic or Shopify plan, use the standard WA.Expert Shopify plugin instead.

Install WA.Expert Shopify app

Install WA.Expert from the Shopify App Store. This adds WA.Expert as an available action in Shopify Flow.

Open Shopify Flow and create workflow

In Shopify Admin → Apps → Flow. Create a new workflow. Select your trigger (Order Created, Customer Created, Inventory Level Changed, etc.).

Add conditions for complex logic

Add Condition blocks for your business rules: Customer lifetime value > ₹50,000, Risk Level = High, Inventory quantity < 20. Shopify Flow supports AND/OR conditions and nested logic.

Add WA.Expert Send WhatsApp action

After your conditions, add the WA.Expert action from the action library. Map Shopify variables (customer.phone, order.total_price, product.title) to WhatsApp template variables. Test and enable.

Sample Shopify Flow → WhatsApp configuration

// Shopify Flow: VIP Customer WhatsApp
// Trigger: Order Created
// Condition: customer.total_spent > 50000

// Action: WA.Expert Send WhatsApp
template: "vip_welcome"
to: {{order.customer.phone}}
variables:
  name: {{order.customer.first_name}}
  order_count: {{order.customer.orders_count}}
  total_spent: {{order.customer.total_spent}}

// Second action: Slack alert to founder
// "VIP customer {{name}} just ordered again"

WA.Expert handles WhatsApp API authentication, template approval, and delivery. You pass trigger data from Shopify Flow — no WhatsApp API expertise needed.

FAQ

Shopify Flow + WhatsApp — common questions

How is Shopify Flow different from the standard WA.Expert Shopify plugin?

The WA.Expert Shopify plugin handles the standard use cases: order confirmation, shipping, COD verification, abandoned cart. Shopify Flow handles advanced business logic — VIP customer detection, inventory alerts, fraud flagging, and any trigger/condition combination you can build in the visual Flow builder.

Do I need both the WA.Expert Shopify plugin and Shopify Flow?

For most stores: use the WA.Expert plugin for all standard order notifications, and use Shopify Flow only for advanced automation that requires complex conditions. Both work simultaneously — there is no conflict.

What Shopify plan is needed for Flow?

Shopify Flow is available on Shopify Advanced (₹22,680/month) and Shopify Plus (₹1,82,250/month). If on Basic or Shopify Standard, the standard WA.Expert Shopify plugin covers all standard automation needs. Flow is worth it for stores at ₹10Cr+/month scale with complex operational requirements.

Can Shopify Flow trigger WhatsApp for B2B wholesale orders?

Yes — Shopify B2B (available on Shopify Plus) has specific Flow triggers for wholesale orders. When a B2B customer places an order, Flow can fire a WhatsApp to both the customer and the assigned account manager with order details and expected delivery.

Can I use Shopify Flow for subscription billing (Recharge, Bold)?

Yes — Recharge and Bold Subscriptions have Shopify Flow connectors. Subscription-specific triggers (upcoming renewal, payment failed, subscription paused) can fire WhatsApp via WA.Expert through Flow.

What are the most impactful Shopify Flow + WhatsApp use cases for Indian D2C brands?

Top 3 for Indian D2C: (1) VIP customer recognition (LTV > ₹25,000) — personal WhatsApp from founder drives retention and referrals. (2) Low-inventory alerts to operations team — prevents stockouts during sale periods. (3) High-value order review (orders above ₹10,000 with new customer + COD) — manual verification before dispatch reduces fraud losses.
