ONDC Project Development Plan

11 April 2023



Open Network for Digital Commerce (ONDC) is a market-led initiative aimed at enabling interoperability in Digital Commerce.

Based on the principles of Openness, it aims to enable unbundling Digital Commerce, democratising Digital Commerce and unlock value for all parts of Digital Commerce, as well as enable innovation to unlock the next chapter of Digital Commerce. — ONDC LinkedIn

ONDC uses async APIs, which buyer apps and seller apps have to integrate to use the network.The APIs starting with on_ are callback APIs/webhooks.

Example. The buyer app will call search API to search an offering. Once this call is sent, the buyer app will get a unique id in response. Now the on_search hook of the buyer app will be called by the network to provide the result of the search from the sellers.

How does it work?:

ONDC is not a website or an app but it's a network. An open network built on top of Beckn protocol that makes it possible for any buyer/seller/logistics partner/credit provider, etc. to communicate with each other in a standardized language.Which in turn makes the ecosystem open for anyone to participate.So any buyer can use a buyer app to search for any products/services and sellers can list their offerings and serve orders.

Benefits of ONDC?

Here are the points about the benefits of ONDC:

  • Increased access to customers: By connecting to the ONDC platform, businesses can reach a wider audience and expand their customer base beyond their local market.

Who is the buyer app?

The buyer app on ONDC is a mobile application designed for buyers to easily purchase products and services from sellers registered on the ONDC network. The app provides a user-friendly interface and features such as product search, order tracking, and payment processing.

Use Cases:

Use Case for Search:

Ramesh wants to buy 100ml of Milk using the Buyer App, He searches the product using the product name, Using Search API to discover the product based on Ramesh's specific location from the large network of seller available in the ONDC


Use Case for Select:

Ramesh uses the search API response to select products and adds them to his cart. Later on, he can modify the list of products in his cart by adding or removing items as needed. It is important to note that ONDC will not be involved in any interactions between the buyer and seller after the search API. ONDC only facilitates the initial handshake between the buyer and seller during the search API process.


Use Case for Init:

In order to place the order on the buyer app, Ramesh needs to proceed with payment. However, before doing so, he must provide his billing and shipping address. This is necessary to ensure that the products can be delivered to the correct location. Ramesh must accept the delivery charges and any additional charges that may apply before completing his order.


Use Case for Confirm:

Once Ramesh has selected the products and provided his billing and shipping address, he can proceed to order the products with a single click. After he has made the payment successfully, the order will be placed successfully. This means that the seller will receive the order details and can begin processing it. It is important for Ramesh to ensure that he has reviewed his order carefully before completing the purchase, as any errors or issues may result in delays or additional charges. However, assuming that everything is in order, Ramesh can expect to receive his products within the specified delivery timeframe.
