I already have a WordPress site whose key pages and layout were generated with AI. WHMCS is installed on the same server for billing and provisioning, and the two platforms are partially connected. For this first milestone I need two concrete additions: 1. A real-time domain search widget that uses the WHMCS API. When a visitor types a name, the field should query WHMCS instantly and display availability results without page reloads. I only need the availability results (no alternative suggestions for now) and a clean “Add to Cart” flow that hands the name straight to the existing WHMCS cart. 2. Single-sign-on with Google. A user who clicks “Continue with Google” on WordPress should be created or matched inside both WordPress and WHMCS, then logged in seamlessly on both systems. Please base this on Google OAuth 2.0 and keep token refreshes transparent to the user. Acceptance criteria • Domain widget shows live availability status returned by WHMCS in under two seconds. • Selected domains transfer correctly into the WHMCS checkout with pricing intact. • One-click Google SSO works for new and existing users across WordPress and WHMCS sessions. • All code is delivered as installable plugin/snippet with brief setup notes so I can re-deploy on staging. Tech you will probably touch: PHP, WHMCS API, WordPress hooks, JavaScript/AJAX, Google OAuth 2.0. If you have a preferred framework for the front-end search component, let me know—React, Vue, or vanilla JS are all fine as long as it stays lightweight. This is the opening task of a longer roadmap, so tidy, well-commented code matters.

Hi there, We’ve developed similar solutions where we integrated WHMCS with WordPress for seamless user experiences. For example, we created a custom WordPress plugin that allowed users to log in with their WHMCS credentials, automatically syncing their accounts and ensuring they were always up-to-date. We can also enhance your existing WHMCS setup by adding a dedicated product for domain registration, allowing users to purchase domains directly from the WHMCS interface. This way, you can manage all domain-related tasks, such as renewals and transfers, directly within WHMCS. In addition to PHP, I’m well-versed in JavaScript and can handle both front-end and back-end tasks efficiently. Let’s schedule a quick 10-minute call to discuss your project in more detail and see if I’m the right fit for your needs. I’m eager to learn more about your exciting project. Best regards, Adil

Hi! I can help you with both the live domain search widget and the Google SSO bridge between WordPress and WHMCS. I'd use vanilla JS with AJAX calls to the WHMCS DomainWhois API endpoint for the real-time lookup, keeping it lightweight and under that two second target. For the SSO piece, I'll handle the Google OAuth 2.0 flow on the WordPress side then sync the user into WHMCS using their API so sessions stay linked. I'm Edward, 10+ years with PHP and WordPress. Clean, well-commented code is how I work anyway so this fits well, especially knowing there's a longer roadmap ahead. Happy to chat through the approach.

Hi, I hope you are doing good Understanding your requirements: As per my understanding, you already have WordPress and WHMCS partially integrated and now need two major improvements: 1. Real-time domain search using WHMCS API 2. Google SSO between WordPress and WHMCS using OAuth 2.0 Pain point and solution: While integrating WordPress with WHMCS, the major challenge is maintaining smooth authentication, session sync, and fast API response handling without affecting checkout flow or user experience. To handle these situations, I focus on optimized AJAX/API handling, secure OAuth implementation, proper token/session management, and lightweight scalable architecture so future maintenance becomes easier. My skills and experience: I have around 13 years of experience in PHP, WordPress, JavaScript/AJAX, API integrations, OAuth authentication, and backend development. I have worked on custom integrations, authentication systems, and scalable web applications. Queries: 1. Are WHMCS APIs already configured? 2. Should Google SSO support new registrations also? 3. Any existing auth plugins currently in use? 4. Plugin based setup or direct theme integration? Best regards, Davinder

Hi, I’ve worked on WordPress + WHMCS integrations before, and the important part here is making both systems feel like one platform instead of two separate applications stitched together. Your two requirements are very achievable with lightweight PHP/AJAX integration and proper session handling between WordPress and WHMCS. For the domain search flow, I’d use a lightweight live-search component (probably vanilla JS/AJAX to keep it fast) connected directly to the WHMCS API so users can check availability instantly and move directly into the existing WHMCS cart without page reloads. For Google SSO, the focus will be properly syncing users between WordPress and WHMCS while keeping login/session behavior seamless for both new and existing accounts. I can help with: – WHMCS live domain availability search – AJAX-powered “Add to Cart” flow – Google OAuth 2.0 SSO integration – WordPress ↔ WHMCS user/session sync – installable plugin/snippet delivery – clean, documented, maintainable code Relevant experience includes PHP, Laravel, WordPress customization, API integrations, authentication workflows, and dashboard systems. A quick question: are WordPress and WHMCS already sharing the same top-level domain/session scope, or are they running on separate subdomains currently? Feel free to message me and we can discuss the integration flow further. Waseem

Hello, I am ready to dive into your project immediately. I’ve integrated WordPress and WHMCS environments before where the key challenges were synchronizing authentication states, preserving cart/session data, and keeping API-driven interactions fast without breaking existing provisioning flows. For your milestone, I’d build a lightweight AJAX-based domain lookup component tied directly to the WHMCS API with clean cart handoff logic, then implement Google OAuth SSO that maps users consistently across both WordPress and WHMCS sessions while keeping the authentication flow seamless for both new and returning users. I want to discuss with you in more detail. Kind regards, Mojjammil

Hi, I can implement both WHMCS live domain search + Google OAuth SSO cleanly as a lightweight WordPress plugin without breaking your existing setup. I’ve worked with WHMCS API integrations, WordPress hooks/AJAX components, and OAuth 2.0 flows where real-time availability checks and cross-platform session sync (WordPress ↔ billing systems) need to stay fast, secure, and minimal. Quick alignment: is your WHMCS currently using standard API credentials or a custom endpoint wrapper? should SSO sync user roles/permissions between WordPress and WHMCS or only authentication identity? Let’s connect in chat and confirm integration details. Pricing and timeline can be finalized after reviewing your current WHMCS–WordPress connection structure.
