WHMCS Client Mobile App

This package builds a branded Android and iOS app for your hosting company where clients sign in with their WHMCS details and see their services, invoices, support tickets and domains. It suits hosting providers and resellers who run WHMCS and want customers to check a due date or answer a ticket without opening a laptop.

How the app talks to WHMCS

WHMCS API credentials carry admin-level power, so they never go inside the app. A small Laravel bridge on your server holds them, checks each client's login through the ValidateLogin action and returns only that client's own records, using calls such as GetClientsProducts, GetInvoices, GetTickets and GetClientsDomains. The API role is limited to the actions the app needs, and the bridge rate-limits login attempts. Replies go in through AddTicketReply, so your staff keep answering from the normal WHMCS admin.

Paying invoices and placing orders

Pay buttons open the invoice in your WHMCS client area through a single sign-on token, so your existing gateways, credit balance and tax settings all keep working. On Premium, clients also order products and domains from your WHMCS catalog, search for a domain, change nameservers and request upgrades; each order is created in WHMCS and paid on its invoice. Store reviewers sometimes question payment flows in hosting apps and their decision is final, so I check the current guidelines before submitting.

Push that follows WHMCS events

On Business and Premium, WHMCS hooks for new invoices, payment reminders and staff ticket replies send a push to the right client's phone. A customized client area theme does not get in the way, because the app uses the API rather than your templates. Data from a third-party module that the WHMCS API does not expose needs the custom module extra. More on connecting WHMCS to other systems is on WHMCS API integration.
