Make Your Systems Work as One.
Your website shouldn’t be an island. We build custom API and webhook integrations that connect your site to your POS, CRM, payments, shipping, and communication tools — so data flows automatically, and nothing gets typed twice.
Website integration is the practice of connecting your website to the other systems that run your business — your point of sale, CRM, payment gateway, shipping carriers, and communication tools — so information moves between them automatically.
Most business websites operate in isolation. Orders get re-typed into the POS. Customer details live in three different systems. Online stock drifts out of sync with the shelf. Every one of those gaps costs time, causes errors, and frustrates customers.
At GNA Solutions, we build these connections ourselves using each platform’s API and webhooks — not just off-the-shelf plugins. That means we can handle many of the edge cases generic connectors struggle with. And because we’ve been developing on WordPress, WooCommerce, and Shopify since 2011, every integration is designed around how your business actually operates.
The result: your website stops being a brochure, and starts being part of your operations.
If it has an API or supports webhooks, there's a good chance we can connect it. Below are the integration categories we work with most, ranging from systems we've delivered in production to ones we've scoped and can build.
Products, categories, stock, members, and orders flow both ways between your point of sale and your online store — automatically, in real time.
Configured properly, not just switched on — fraud and Radar rules, payment method control, and checkout flows optimised for conversion.
Enquiries, property listings, and client data sync the moment they change in your CRM — no manual re-entry, no stale information.
Transactional email and SMS that actually reach your customers — with sender authentication, deliverability hardening, and automated notifications.
E-signature workflows and identity or sanctions screening built directly into your website — contracts signed and checks completed without leaving the page.
Live shipping rates at checkout, automated tracking updates, and custom delivery date scheduling — connected straight to your store.
Every integration follows the same disciplined path — so you know exactly what syncs, how often, and what happens when things go wrong, before a line of code goes live.
We map your platforms, data flows, and the manual double-handling that shouldn't exist — and confirm what each system's API can actually do.
A clear proposal covering what syncs, how often, in which direction, and how errors are handled — agreed before we build anything.
Developed and validated on staging with your real product, and order data — before anything touches your live site.
Deployed with error logging. Ongoing maintenance plans are available to keep it running as APIs change.
Off-the-shelf connectors break on edge cases. We write the integration code ourselves and design it around how your business actually works — with maintenance plans available to keep it running as platforms change.
