Prefilled, OTP-verified addresses at checkout.
One API returns a shopper's consented shipping address so your checkout autofills in a tap. Fewer fields, fewer wrong addresses, fewer RTOs — and a faster path to buy.

The solution
An address-prefill API built for Indian checkout
Everything you need to turn a phone number into a verified, ready-to-ship address — securely and fast.
OTP-verified address prefill
A single API call returns the shopper's shipping name, address, and pincode — consented via a one-time code — so your checkout autofills in a tap instead of a 9-field form.
Seamless Shopify integration
Drop it into your Shopify checkout or theme with a few lines. No data migration, no heavy SDK — call the endpoint, prefill the fields, done.
Built for India · 93%+ match
Tuned for Indian numbers, PIN codes and address formats, with a 93%+ match rate across live e-commerce order data.
Double-digit millisecond response
A low-latency edge that answers in double-digit milliseconds, so prefill feels instant and never slows your checkout.
Drop-in for Shopify checkout
Notifik plugs straight into your Shopify store. Call the prefill endpoint with the shopper's verified number and populate the address fields — no data migration, no bloated SDK, no checkout slowdown.
