Zendesk for WHMCS brings Zendesk support tickets directly into the WHMCS client area. Clients can manage their support requests without signing in to a separate Zendesk portal, while support staff continue working entirely in Zendesk.

The module replaces the native WHMCS client ticket pages and homepage ticket data with the logged-in requester's Zendesk tickets. It also displays tickets received by Zendesk through email when the requester address matches the client's WHMCS email address.

Clients can:

• View their Zendesk tickets and public comment history
• Open new tickets directly in Zendesk
• Post public replies
• Upload up to five attachments per ticket or reply
• Mark tickets as solved
• Associate a selected WHMCS service or domain with an optional Zendesk custom field

Zendesk remains the only support-ticket datastore and sends all requester notifications. Ticket subjects, messages, replies, attachments, history and statuses are not copied into native WHMCS support tables. Private Zendesk notes remain hidden from clients.

The integration uses Zendesk OAuth with automatic encrypted token storage, renewal and retry handling. It requires no synchronization cron, webhook, queue, native WHMCS support department or duplicated ticket history.

Support staff manage tickets in Zendesk. Clients remain in the familiar WHMCS client area.

Requirements:

• WHMCS 9.0 or later
• PHP cURL
• HTTPS-enabled WHMCS installation
• Zendesk API and ticket attachments enabled
• A dedicated active Zendesk administrator for the OAuth client
