- WALoops now integrates natively with Shiprocket (Fastrr) Checkout to recover abandoned carts on WhatsApp.
- Send personalised messages within minutes of a shopper dropping off — featuring their real name, cart total, product image, and a one-tap checkout link.
- AI Agent follow-up: If the customer replies with doubts about sizing, delivery, or payment, your catalogue-trained AI agent answers immediately and closes the sale.
- No coding or Zapier needed. Setup takes under 2 minutes with WALoops's dedicated Shiprocket webhook connector.
- 0% markup on Meta WhatsApp message rates (about ₹0.8631 per marketing message in India).
For Indian D2C ecommerce brands, checkout abandonment is a constant challenge. Across mobile-first storefronts, over 70% of shoppers who initiate checkout leave before completing payment. While traditional email reminders see open rates below 20%, WhatsApp messages in India achieve over 95% open rates and prompt response times.
Shiprocket's Fastrr Checkout has become one of the most popular 1-click checkout solutions in India. Up until now, connecting Fastrr abandoned cart webhooks to WhatsApp required complex custom scripts or third-party webhooks. With WALoops's native Shiprocket Checkout app, you can now launch automated, AI-assisted recovery campaigns in minutes.
Why Shiprocket Fastrr carts get abandoned
Fastrr Checkout streamlines checkout by pre-filling saved addresses, phone numbers, and payment preferences. However, shoppers still drop off due to common friction points:
- Payment hesitation: Unsure whether to pick UPI or Cash on Delivery.
- Delivery questions: Wondering if their order will arrive in time for an upcoming event or festival.
- Sizing or product doubts: Second-guessing fit or color before committing money.
- Distractions: Mobile phone notifications or poor connectivity during OTP entry.
When you reach out on WhatsApp with the exact product they left behind, you meet shoppers on the channel they check dozens of times a day.
How the integration works
abandoned_checkout webhook. WALoops receives the event, normalises the data (including Indian phone number formats), and immediately queues your automated WhatsApp sequence.
| Step | Action | Time to complete |
|---|---|---|
| 1. Connect App | In WALoops, go to Apps → Shiprocket Checkout and click Connect to get your webhook URL. | 30 seconds |
| 2. Configure Webhook | Paste the webhook URL in your Shiprocket/Fastrr dashboard under Settings → Webhooks → Abandon Cart. | 1 minute |
| 3. Set Up Automation | Create an automation in WALoops with your approved WhatsApp recovery template. | 1 minute |
| 4. AI Takeover | Enable WALoops AI Agent so replies to recovery messages are automatically answered. | Instant |
Available template variables
WALoops extracts the full cart and customer context from Shiprocket's webhook payload, allowing you to build highly personalized messages:
| Variable | Example value | How to use it |
|---|---|---|
{{customer.first_name}} | Priya | Greet the customer personally in your opening line. |
{{customer.name}} | Priya Sharma | Full customer name for formal communications. |
{{customer.phone}} | 919876543210 | Auto-formatted E.164 phone number. |
{{cart.total}} | 1,499 | Show the exact payable amount. |
{{cart.currency}} | INR | Store currency. |
{{cart.product_summary}} | Cotton Embroidered Kurta | Name of the item left in the cart. |
{{cart.product_image}} | https://cdn.store.com/item.jpg | Use in template header image for high visual recall. |
{{cart.abandon_url}} | https://store.com/?cart-resume=... | Button URL so the customer returns to checkout with one tap. |
Smart phone number handling for India
One common headache with Indian checkout webhooks is phone number formatting. Shiprocket Fastrr often sends raw 10-digit mobile numbers (e.g. 9876543210) without the international country code.
WALoops automatically detects 10-digit numbers and prepends India's 91 country code, ensuring messages are delivered without API rejection. If the number already includes +91 or 91, WALoops cleans it up seamlessly.
The power of combining WhatsApp automation with an AI agent
Traditional recovery messages are a dead end: if a customer replies asking "Can I get this delivered by Friday?", "Is size M true to size?", or "Can I pay ₹200 advance and rest COD?", the lead goes cold unless a live support agent is online.
With WALoops, your AI Agent is connected directly to the chat:
- Catalogue awareness: The AI knows your products, inventory, size charts, and shipping policies.
- Instant answers: Doubts are answered in seconds in natural English, Hindi, or Hinglish.
- Dynamic offers: If configured, the AI can offer a 5% or 10% instant discount code to seal the purchase.
- COD confirmation: Can confirm orders and convert hesitant COD buyers into prepaid customers with payment links.

}What does it cost?
WALoops does not charge per-message surcharges or markup on WhatsApp. You pay Meta directly at official rates:
- Meta marketing message cost: Approximately ₹0.8631 per delivered message in India.
- WALoops platform: Included in all WALoops plans with full automation builder and AI agent capabilities.
- Return on Investment: Because recovering even a single ₹1,500 cart covers the cost of hundreds of WhatsApp messages, recovery campaigns regularly generate 20x to 40x ROI.
