Concept Project
Concept visualisation — not a real screenshotCustom Software2026
Demo Project — Integration Platform
A sample custom software concept that synchronises data between separate business systems.
- Node.js
- Python
- MongoDB
- Docker
06 · Supporting capability
Systems that talk to each other — and tell you when something goes wrong.
Reliable connections between your software and the services you depend on.
What this service is
We design and build REST APIs for your own products and connect your software to external services — payment, shipping, accounting, CRM or internal systems. Every integration includes validation, authentication, retries and logging, so failures are visible instead of silent.
Who it's for
- Businesses entering the same data in several systems
- Products that need a public or partner API
- Teams with fragile, undocumented integrations
- Companies connecting a new tool to existing software
Problems it addresses
- Double data entry and inconsistent records
- Integrations that fail silently
- No documentation for existing endpoints
- Insecure or shared API credentials
How we solve them
- Clear, versioned API contracts
- Validation at every boundary
- Retries, idempotency and alerting
- Secrets kept in server-side configuration

How the work runs
- 01Inventory of systems, data and provider documentation
- 02API contract and data mapping
- 03Implementation with sandbox testing
- 04Monitoring, documentation and go-live

- Error logging and alerts
- Developer documentation
What you can expect
A map of the systems involved and the data exchanged between them, documented endpoints, and error handling that makes failures visible instead of silent.
After delivery
Integrations change when the other side changes. We can monitor them, update them when a provider changes its API and add new connections.

Questions about this service
Can you integrate any third-party API?
If the service provides a documented API and you have the necessary account access, usually yes. We check the documentation and limits before committing to scope.
What happens when the external service is down?
Integrations are designed to retry, queue or report failures depending on the use case, so data is not lost silently.
Do you maintain integrations after launch?
Providers change their APIs over time. Ongoing maintenance can be agreed as part of a support arrangement.
