When your tools do not talk
Data gets copied by hand between the shop, the CRM and the inbox, and mistakes creep in. An integration moves it automatically.
The usual way
- Data copied between tools by hand
- Integrations that fail without telling anyone
- A plugin for every connection
How I do it
- Data moves on its own
- Failures logged and retried safely
- One tidy integration you can maintain
What an integration covers
Payment gateways
Checkout connected and tested end to end. I wrote the payment gateway plugin for Moneybag.
Email, CRM and forms
Enquiries and orders sent where your team works, with confirmations that arrive.
Delivery and couriers
Order and delivery details handed to the courier service you use.
Your own API
A clean API for your product so a mobile app or a partner can build on it.
Failure handling and logs
Retries, timeouts and a log, so a problem is visible before a customer reports it.

How an integration project runs
- Step 01
Study your competitors
I look at what competitors do well and where they leave gaps, before a single screen is drawn.
- Step 02
Design the UI and UX
I design the screens myself, so what you approve is what gets built.
- Step 03
Build frontend to backend
Pages, accounts, orders, payments and the admin dashboard, built as one job.
- Step 04
Launch and look after it
Speed checked on a phone, then backups, monitoring and changes through website care.

Your questions about API integration services
Ask something else on WhatsAppHow much do API integration services cost?
Integrations are quoted per job after I read the documentation of the services involved. Extra developer time on an existing project is $25 an hour.
Which services can you connect?
Anything with a documented API: payment gateways, email and SMS, CRM, delivery services and your own systems. If I have not used a service, I read its docs first and tell you what to expect.
What happens when the other service goes down?
The integration retries safely, logs the failure and does not charge or send twice. You can see what failed and when.
Can you build an API for my product?
Yes. I build the API as part of a web application so mobile apps and partners can use it.
