Custom Integrations and APIs

I connect your website with the tools that run your business. Synced data and unified processes — no duplicate manual work, no information silos.

Your website, connected to your business

When your website, CRM, invoicing and booking system don’t talk to each other, someone ends up copying data by hand. That costs hours every week and leads to errors that your customers end up paying for.

I connect your website with the tools you already use —CRM, ERP, payments, bookings, maps or any service with an API— so information flows on its own and is always up to date. If there’s no ready-made integration, I build a custom one.

  1. Custom APIs

    I build custom connections with any service that offers an API: pulling data in, sending it out and keeping it in sync so your website talks to the rest of your stack.

  2. CRM and ERP

    I integrate your website with your CRM or ERP so every lead, order or customer goes straight into your systems — no copy-pasting, no information lost along the way.

  3. Payments with Stripe

    One-off payments, subscriptions or custom billing with Stripe, integrated securely and with a carefully crafted payment experience.

  4. Databases and backend (Supabase)

    When your project needs its own logic, I build the backend with Supabase: authentication, database and APIs ready to grow.

  5. Bookings and maps

    Booking and appointment systems, plus interactive Mapbox maps for businesses with a physical location or services organized by area.

  6. Webhooks and syncing

    I automate the flow of data between platforms with webhooks, so everything updates in real time without manual intervention.

How I work

A clear method so you always know where the project stands and what comes next.

  1. Paso 01

    Mapping your tools

    I review which systems you use, what data each one handles and where work is being duplicated. Within 48 hours you’ll have a firm proposal.

  2. Paso 02

    Integration design

    I define what data moves, in which direction and when, with only the minimum permissions needed.

  3. Paso 03

    Development and testing

    I build the connections and test them with real data in a safe environment before touching production.

  4. Paso 04

    Go-live

    I switch on the integration, monitor it and hand over documentation so you know exactly what it does.

Technologies and tools

I choose each tool for what it brings to the project, not out of habit.

CRMs and ERPs, payment gateways like Stripe, booking systems, Mapbox maps, databases like Supabase, email marketing and virtually any service with an API or webhooks.

If it has an API, I build a custom connection. If it doesn’t, I find another way: scheduled imports, webhooks or a small middleware service that acts as a bridge.

As a guide, integrations start at around €900 and depend on how many systems need to be connected and how complex the data is. After an initial call, I’ll send you a firm proposal within 48 hours. Calculate the price of your website

Synced data and zero duplicate manual work: form submissions go straight into your CRM, orders reach your ERP and bookings show up in your calendar. Fewer errors and more time for your business.

Yes. I work with encrypted credentials, minimum permissions and secure connections, and I document every integration so you know exactly what data is sent and where it goes.
