With the partnership between Jio Mart and Whatsapp, WhatsApp will be the main means of communication between kirana stores and customers. To use the service, a user has to add JioMart's number 8850008000 on the smartphone, and send a 'Hi' on WhatsApp.
A link is then sent by JioMart that redirects users to a webpage where they have to fill in details like name and address before visiting the online grocery market. The link is valid for 30 minutes. On the Marketplace, a user can buy a product from the catalog displayed.
If you want, you can directly visit the official website of Jio Mart - https://www.jiomart.com/.
