COD OTP & Fraud Verification

Key Features

SMS OTP phone verification on every COD order — confirmation gated until the one-time code entered by the shopper is validated against the sent code

Configurable verification flow: inline at checkout (where your plan permits checkout extensibility) or via a branded post-purchase verification page linked from order-confirmation SMS/email

CAPTCHA challenge to block bots and scripted junk orders before an OTP is even spent

Risk-scoring engine that weighs signals you choose — repeat suspicious numbers, address/phone mismatch, disposable/VOIP number patterns, prior RTO history, order velocity

Phone-number and customer blocklists with one-click add from any flagged order in the Shopify Admin

Auto-cancel or auto-hold of unverified orders after a configurable timeout window, with optional restock

Order tagging and order metafields written via the Admin GraphQL API so verification state is visible and filterable in native Admin order views

Webhook-driven processing on orders/create and orders/updated — verification runs server-side, not just client-side, so it can't be bypassed

Multi-location inventory aware — stock is not committed to unverified orders, reducing oversell on real demand

Your choice of SMS gateway integrated (Twilio, MSG91, Vonage, or a regional provider) with per-country sender IDs and templates

Configurable retry limits, OTP expiry, and resend throttling to control SMS spend and stop OTP abuse

Admin dashboard view of verification rate, flagged orders, and blocklist activity inside the embedded app

About this Product

Cash-on-delivery is your highest-converting payment method and your biggest leak. Fake numbers, joke orders, and serial returners drive your RTO (return-to-origin) rate up while you eat reverse shipping, packaging, and restocking costs. COD OTP & Fraud Verification closes that gap by forcing every COD order to prove a working phone before it ever reaches your packing table.

This is a build-to-order Shopify app — ECOSIRE builds it against your exact theme, SMS provider, and fulfillment flow, then installs and configures it on your store. It is not an instant App Store download. After you order, we scope your requirements, develop, deploy via Shopify OAuth as a custom app, and hand you a working system with documentation.

What it does: When a shopper places a COD order, the app fires an SMS OTP to the entered number; the order is only confirmed once the code is validated. A CAPTCHA challenge blocks bots at checkout or on a post-purchase verification page. A risk-scoring engine evaluates each order against signals you choose — repeat fake numbers, mismatched address/phone, prior RTO history, blocklists — and flags or auto-holds high-risk orders. Unverified orders can be auto-cancelled or tagged for manual review after a configurable window.

Technically, it integrates through the Admin GraphQL API and order webhooks (orders/create, orders/updated), writes verification state to order metafields and tags, and respects multi-location inventory so nothing is held against stock until an order clears. Your team works entirely inside the familiar Shopify Admin — flagged orders, OTP status, and risk scores show up where you already manage fulfillment. Built, deployed, and supported by ECOSIRE Private Limited.

Who this is for

COD-heavy regional store owner

Sells in markets where cash on delivery dominates and fake or prank orders inflate RTO. Wants a working-phone guarantee before crews pack and dispatch, without killing COD conversion.

Operations / fulfillment manager

Owns the packing and dispatch queue and is tired of shipping orders that bounce back. Needs unverified orders auto-held or auto-cancelled and high-risk ones flagged before they hit the warehouse.

Finance / margin owner

Watches reverse-logistics and restocking costs erode margin on COD. Wants measurable reduction in RTO and a blocklist that stops repeat offenders from re-ordering.

Frequently Asked Questions about COD OTP & Fraud Verification

How long until the app is live on my store?

Because this is built to order, there is a lead time — it is not an instant install. After your purchase we confirm requirements (your SMS provider, target countries, risk rules, and verification flow), then build, test, and deploy. A standard configuration typically takes a few business days to two weeks depending on complexity, custom risk logic, and SMS-provider setup. We give you a firm timeline once scope is confirmed.

Do you provide ongoing support and updates after launch?

Yes. Every build includes a post-launch support and warranty window for bug fixes and for keeping the app compatible with Shopify Admin GraphQL API and webhook changes. After that period, ongoing support, new rules, and feature additions are available as a maintenance arrangement. ECOSIRE Private Limited builds and supports the app directly.

Which SMS provider does the OTP use, and who pays for the messages?

We integrate the SMS gateway of your choice — Twilio, MSG91, Vonage, or a regional provider that gives you the best rates and deliverability in your markets. SMS costs are billed by that provider directly to you; we configure sender IDs, templates, retry limits, and resend throttling to keep your spend predictable.

Can verification run inside Shopify checkout itself?

Where your Shopify plan and checkout extensibility allow it, OTP can be presented inside the checkout flow. Otherwise — and most reliably across plans — we run verification as a branded post-purchase step linked from the order-confirmation SMS/email, backed by server-side webhook logic so it cannot be bypassed. We recommend the right approach for your plan during scoping.

What happens to an order that is never verified?

You decide the policy. After a configurable timeout, an unverified order can be auto-cancelled (with optional restock), or auto-held and tagged for manual review so your team can decide. Either way the order is clearly tagged and its OTP/risk state is written to order metafields, so it's filterable in your normal Admin order views.
