META OFFICIALPowered by Meta Graph API for Instagram Professional Accounts & Razorpay India Payments
Transform Direct Messages into 1-Click Checkouts

Turn Instagram Conversations into Instant DM Commerce

Enable customers to discover viral drops on Instagram, receive automated product cards in DMs, and complete secure checkouts with Razorpay or COD without ever leaving the conversation funnel.

The Core Architecture

Instagram is for Discovery. OnSpotBuy Handles Commerce.

We respect Meta’s API policies with 100% compliance. No unsupported native checkout iframes or password scraping.

1

Discovery & DM

Customer messages “HOODIE” or comments on an ad drop.

2

Automated Card

Webhook triggers verified product card with image and “Buy Now” CTA.

3

Secure Checkout

Fast mobile-first page selects variant, verifies live inventory & shipping.

4

Razorpay / COD

Server HMAC signature verification locks payment and deducts stock safely.

5

Courier Tracking

Seller generates AWB (Delhivery, Blue Dart) & customer tracks live delivery.

Enterprise Ready

Engineered for High-Conversion Direct Commerce

Built with Next.js App Router, multi-tenant isolation, cryptographically verified webhooks, and Razorpay server-side SDK.

Meta Official OAuth & Messaging

Connect Instagram Professional accounts securely. Only requests required scopes (instagram_manage_messages). Handles token expiry, renewal, and includes an interactive in-dashboard phone simulator.

Razorpay Signed Payments & COD

Never trusts client prices. Backend calculates subtotals, verifies HMAC-SHA256 signatures, logs raw body webhooks idempotently, and prevents stock overselling.

Courier Fulfilment & Live Tracking

Integrated tracking URL generators for Delhivery, Blue Dart, Shiprocket, and DTDC. Customers track their deliveries step-by-step with secure guest tokens.
