ONDC Network API Integration
Discover catalogs and place orders across the Open Network for Digital Commerce as a buyer/seller app.
What ONDC Network API integration does
ONDC is an attempt to unbundle e-commerce. Rather than a platform owning discovery, ordering and fulfilment end to end, participants implement a shared protocol and interoperate — so a buyer app can surface catalogs from sellers it has no bilateral relationship with, and a seller reaches every buyer app on the network from a single integration.
The protocol is Beckn-based and asynchronous, which is where most teams underestimate the work. Search does not return results synchronously; it broadcasts and results arrive as callbacks. Ordering, fulfilment and status follow the same pattern. A team whose experience is with conventional REST marketplaces typically has to rebuild its assumptions about state before writing much code.
Our ONDC integration provides that protocol implementation for buyer-side or seller-side participation, so your engineering effort goes into catalog, pricing and fulfilment logic rather than into learning Beckn.
What teams build with it
Buyer app
Search catalogs across the network and place orders with any participating seller without per-merchant integrations.
Seller app
Publish your catalog to the network and receive orders from every buyer app on it.
Category-specific commerce
Participate in a specific vertical — grocery, food, mobility — with catalog and fulfilment logic tuned to it.
Additional demand channel
Run ONDC alongside an existing Shopify or WooCommerce storefront on shared inventory.

ONDC Network API integration — FAQs
What does joining ONDC involve?
Implementing the Beckn-based protocol for your role and completing network onboarding. Our connector supplies the protocol implementation, which is the part that otherwise dominates the timeline.
Can we sell on ONDC and keep our own storefront?
Yes, and most sellers do. ONDC becomes an additional demand channel sharing the same inventory as your existing storefront.
How is ONDC different from a marketplace?
A marketplace is an intermediary that owns the relationship. ONDC is a protocol: buyers and sellers interoperate without a single platform sitting in the middle.
