WhatsApp Chat Support

WhatsApp Chat Support Add-on for CS-Cart allows customers to connect with support teams quickly through WhatsApp.

The WhatsApp Chat Support add-on for CS-Cart lets customers reach a store's support team directly through WhatsApp. It places a WhatsApp icon on the storefront that either redirects shoppers to WhatsApp Web or opens a chat box with preset text, image, and colours. Because it supports separate settings for the main store and for individual vendors, each seller on a marketplace can manage its own WhatsApp support number and appearance. It is aimed at CS-Cart store owners and Multi-Vendor sellers who want faster query resolution and a familiar messaging channel for customer support.

WhatsApp Chat Support Add-on for CS-Cart allows customers to connect with support teams quickly through WhatsApp. A WhatsApp icon appears on the storefront, making it easy to start a chat. The add-on supports separate settings for the main store and individual vendors, so each seller can manage their own WhatsApp support.

The add-on includes both admin and vendor-level controls. Admin manages global settings, layout placement, redirection options, and vendor plan permissions. Vendors can update their own support number, contact image, chat text, colors, and display options from the vendor panel.

Customers either get redirected directly to WhatsApp Web or see a chat box with preset text, image, and color settings. This setup ensures quick communication, faster query resolution, and a smooth support experience through a trusted messaging platform.

Frequently asked questions

How do customers start a WhatsApp chat from the storefront?

A WhatsApp icon appears on the storefront. When a customer clicks it, they are either redirected straight to WhatsApp Web or shown an on-page chat box with preset text, image, and colour settings, depending on how the store has configured the redirect option.

Does it work with CS-Cart Multi-Vendor and per-vendor support numbers?

Yes. The add-on supports separate settings for the main store and individual vendors, so each seller can set its own support number, contact image, chat text, colours, and display options from the vendor panel.

What can the admin control versus the vendor?

The admin manages global settings, layout placement, redirection options, and vendor plan permissions. Vendors control their own support number, contact image, chat text, colours, and display options for their storefront.

What is the difference between the redirect and the built-in chat box?

When the redirect option is enabled, clicking the support icon sends the customer directly to WhatsApp Web. When it is disabled, the icon opens a WhatsApp chat box using the text, colours, and support image set in the Settings tab.
