API & third-party integrations

Your website, talking to every tool you run.

Clean integrations with payment, CRM, shipping, booking, and content APIs.

A website rarely works alone. Orders flow to fulfilment, enquiries land in a CRM, bookings sync to calendars, and content comes from a headless CMS. I build those connections so data moves by itself, reliably.

I have integrated payment gateways, storefront APIs, headless CMS platforms, and internal systems across REST and GraphQL, with proper error handling, retries, and logging, so a hiccup in one tool never silently loses a customer.

If a tool you rely on has an API, I can connect your website to it, and leave you documentation that makes the integration easy to live with.
