How We Integrate ONDC With Your Store
ONDC — the Open Network for Digital Commerce — is a Government of India initiative that turns online selling into a shared, open network instead of a set of walled marketplaces. It runs on the Beckn protocol, a set of open API specifications, so any compliant seller node and any compliant buyer app can transact with each other. AppsyOne onboards you as a seller on that network and connects it to the store you already run, so you list once and sell across the whole network.
You join ONDC as a Seller Network Participant, technically a seller node. There are two routes: an Inventory Seller Node (ISN), where your own catalog and inventory sit on your node, and a Marketplace Seller Node (MSN), where a marketplace hosts many sellers on one node. We take your Shopify, WooCommerce or custom store, map its catalog to the ONDC schema, and expose it to the network through the Beckn search, select, init, confirm and fulfilment calls buyer apps use.
The payoff is reach without a landlord. Because ONDC is decentralised, one catalog mapped to the network schema on your own node surfaces inside every compliant buyer app — Paytm, PhonePe Pincode, Magicpin and the growing list behind them — rather than being penned into a single marketplace. With 370,000-plus sellers already trading and settlement and reconciliation handled through the protocol's own flows, it is early enough to be a real opening. We stand you up from your existing store for a fixed setup fee plus a flat monthly, and the seller node stays yours.
