Customers or partners need a supported way to connect to your product.
Authentication, permissions, failure behaviour, versioning and documentation affect whether another team can actually use the interface.
API development services
If your product or internal system needs a stable way for other software to access data or functionality, Galvia can design and build the API, define the rules around it and document it for the teams that need to use it.
Tell us what needs to be exposed, who needs to consume it and what already exists. You do not need a finished API specification.

When to bring us in
An API is not only a list of endpoints. The consumers, permissions, failure behaviour and ownership after launch determine whether other teams can depend on it.
Authentication, permissions, failure behaviour, versioning and documentation affect whether another team can actually use the interface.
A defined interface can reduce dependency between systems, but only if ownership and business rules are clear.
We investigate what the application permits and whether an API, service layer or another supported interface is the right route before committing to a build.
How we start
We start with the consumers and the behaviour they need. That gives authentication, errors, versioning, testing and documentation a real context instead of treating them as afterthoughts.
Agree who will use the API, what data or actions they need, the permissions involved and how success will be tested.
Specify authentication, errors, retries, rate limits, versioning and observability that fit the use case.
Deliver the interface with practical documentation and examples, then agree who owns changes and support after launch.
What happens after the enquiry? The initial conversation is not a full technical audit. Repository access, detailed investigation and implementation are scoped separately.
Published project examples
These are adjacent public engineering examples rather than invented API case studies. They show Galvia working around product integration, connected data, documentation and software other teams need to use.
Stimare / product integration
Galvia created a shared mobile SDK, demo application and supporting documentation for barcode-scanner integration across Android and iOS.

Galvia connected monitoring devices, normalised their readings and delivered the information through a shared cloud platform.

The people behind the work
Galvia is a Belfast software development team. We work alongside your people, explain the trade-offs and document what we build so the result can be understood and maintained.
You can get to know the team and how we approach a project before sharing your brief.
How Martin approaches a projectWhat the work can involve
The useful API is the one another team can integrate with and operate against confidently. That means the contract, failure behaviour, permissions and documentation matter alongside the code.
Design and build an API around the data or functionality your customers, partners or internal systems need. We define the contract around real use cases so the interface does not become a collection of unrelated endpoints.
Build HTTP-based interfaces where REST or another web API pattern is appropriate for the consumers and system. The technology choice follows the operating constraints rather than the keyword on the page.
Define who can do what, how failures are communicated and how consumers should respond. Authentication, authorisation, validation and errors are part of the interface design, not a finishing task.
Provide practical documentation, examples and testing around the interface so another team can use it. If you also need the systems on either side connected, see our custom API integration services.
Keep the technical route proportional to the problem. API development and API integration overlap, but they are not the same job. Development creates the interface a system exposes. Integration connects systems using the interfaces that exist.

Before you enquire
API development creates or extends the interface a system exposes. API integration connects systems using available interfaces. Some projects need both, but separating the two helps clarify ownership and scope.
Sometimes. The right route depends on the application architecture, data access, security model and how safely new interfaces can be introduced. We investigate those constraints before assuming an API can simply be bolted on.
Yes, where REST is appropriate for the consumers and the system. We can also work with other interface patterns when the technical and operational requirements point elsewhere.
Authentication and authorisation are designed around the users or systems that need access and the sensitivity of the actions or data involved. The exact mechanism is selected during technical design rather than promised generically.
They can be part of the delivery scope and normally matter when another team must integrate successfully. We agree the level of automated testing, examples and documentation needed for the consumers and handover.
Yes. Where the requirement includes connecting the API to another application or workflow, that can be scoped as part of the work or through our custom API integration service.
Tell us who needs the interface
Tell us which product or system is involved, who needs to consume the API and what data or actions they need. We review each enquiry before arranging a call.
Commercial conversations are led by Martin Naughton, Galvia’s founder and solution architect. Meet Martin.
