We write the
integration.
Not the plugin.
Most agencies mean "we installed a Zapier step" when they say API integration. We mean we wrote the code — REST endpoints, webhook handlers, custom middleware, real-time sync with error handling and monitoring. These integrations are running live in production right now.
Before WordPress existed,
we were writing the integrations.
Velocity Web was founded in 1998 — before most current web platforms existed. The early years were spent hand-building ecommerce systems, booking engines, and membership platforms in PHP from scratch. That background matters because we understand how systems connect at the data level, not just at the plugin level.
When a client asks whether their Magento store can sync with their POS system, we know the answer because we've built and maintained that exact integration. When someone needs a booking system that doesn't fit a standard plugin, we know what it takes to build one properly — and we know when to recommend a third-party platform instead.
We're honest about scope. Not every integration needs custom code — sometimes a well-configured plugin or Zapier flow is the right answer. But when data accuracy, reliability, and real-time sync are business-critical, that's when you need the real thing, not a middleware wrapper that breaks when either system updates.
These are demonstrable. Several of our live integrations can be shown — not described in a case study, but actually pointed at and walked through. If you're evaluating whether we can handle a specific integration, ask us and we'll show you the closest equivalent we have running.
Six live integrations.
In detail.
Each one built against the platform API, not via middleware. Each one currently running in a production environment.
Real-time bidirectional sync between a physical retail store running Lightspeed POS and a WooCommerce website. Products, stock levels, and order data stay in sync across both channels. Stock sold in-store updates online immediately. Online orders flow into the POS without manual entry. One of the only live Lightspeed integrations at this scale in the South West — and one we can demonstrate.
Live order and project workflow sync between a national Magento 2 store and Monday.com operational boards. Orders from the website flow directly into the relevant Monday.com boards without manual entry — keeping the fulfilment and project teams in sync. Running as part of a three-site cluster under a single retainer, alongside the commercial appliances site and a product microsite.
Automated direct debit collection for membership schemes and subscription billing, integrated directly into WooCommerce checkout via the GoCardless API. Renewals, payment confirmations, and failed payment handling all automated — reducing manual admin for the society team. The same approach is available for any recurring payment or membership model.
Three systems running inside one WordPress build: WooCommerce for merchandise and passes, Events Calendar for the full festival programme, and integrated ticketing for individual events. The entire annual cycle — programme publishing, ticket sales, merchandise, post-event — runs through this single site. The most technically layered WordPress build in the portfolio.
WooCommerce handles submission fee payments for an academic journal. On successful payment, a unique validation code is generated and passed back to the journal submission system — gating access to the submission form. Custom payment logic, unique code generation, and third-party system validation all running in production. An example of integration that goes beyond simple payment processing.
AI chat widget built on Claude with WhatsApp escalation via the Meta Cloud API. When a conversation reaches a threshold that needs human response, it escalates directly into a WhatsApp thread with the business owner — no third-party helpdesk, no ticket queue. Currently being built as part of Momentum Concierge, with H2O Swimming Pools as the first live client.
Plugin, Zapier, or
custom — honestly.
We don't push custom development for everything. A well-configured plugin or Zapier flow is often the fastest and cheapest solution — and when it's the right answer, we'll say so. The honest calculation is what happens when it breaks or the platforms update.
Custom integrations are worth building when: data accuracy matters at every transaction, real-time sync is required rather than periodic batch updates, the systems involved don't have a shared plugin ecosystem, or the integration logic is complex enough that no plugin handles it correctly.
The test is simple: what's the cost of the integration failing? If a failed sync means a customer can buy stock you don't have, or an order never reaches fulfilment, that's a business problem — not a technical inconvenience. Custom code with proper error handling and monitoring costs more up front and costs much less long term.
Periodic sync (5–15 min delay). Breaks when either platform updates. Limited error visibility. Can't handle complex conditional logic.
Real-time webhook-driven sync. Survives platform updates if APIs are stable. Full error logging and alerting. Handles any business logic required.
Silent failure. You find out when a customer complains or you notice stock discrepancies. No audit trail.
Monitored. Alerting fires when errors exceed threshold. Retry logic handles transient failures. You know before the customer does.
Marketing automation, low-volume data transfer, non-critical notifications, simple one-way data pushes.
Inventory sync, order management, payment processing, membership management, anything transactional.
Platforms and systems
we've integrated with.
Grouped by category. Asterisked entries are live integrations currently running in production.
When no platform exists,
we build one.
Sometimes the right answer is custom software, not an integration. Two examples currently live and processing transactions.
Custom PHP gift voucher sales and management system — not a plugin, not a SaaS product. Built from scratch to handle multi-venue sales, gift voucher generation, redemption tracking, and reporting across two restaurant venues in the South West. Thousands of transactions processed. Still running, still maintained.
A fully custom accommodation booking engine built for a Devon campervan hire company with a mixed fleet — Renault campervans and Roller Team / Auto Trail motorhomes. Custom availability calendar, hire period management, vehicle selection, and payment flow. Built when no off-the-shelf booking platform handled vehicle hire with the required flexibility. Running live and processing bookings.
