Open Seller tools > WhatsApp Shop for the active business. Before connecting, the vendor needs a Meta business portfolio, WhatsApp Business Account, business phone number, commerce catalogue and permanent system-user access token with permission to manage the catalogue.
Enter the Meta catalogue ID, WhatsApp Business Account ID, phone number ID and access token. Tuaneka verifies all four with Meta before saving. The access token is encrypted and is never shown again. Never send the token by email, support chat or WhatsApp.
After connection, choose Add to WhatsApp beside a published product or use Sync all published products. Products need a public image. Tuaneka sends the title, description, current marketplace price, sale price, stock, product URL and product image. Active variants are sent as individual WhatsApp catalogue items with their size, colour, SKU, price and stock. A private catalogue-feed URL is also available for Meta Commerce Manager as a fallback.
Turn on automatic sync to queue catalogue updates regularly. Product and inventory changes remain managed in Tuaneka. A failed item does not erase the Tuaneka listing; review the error, correct the product image, publication state, Meta permission or catalogue ownership, then select Sync changes. Disconnecting WhatsApp stops future syncs but deliberately leaves existing Meta catalogue items in place until the vendor removes them in Commerce Manager.
