API & application integration
Connect existing applications so data and actions move between systems in a controlled way.
SYSTEM INTEGRATION
Connect systems so processes do not break between applications.
Organisations often have the right individual systems while the process between them still depends on duplicate entry, exports, manual checks or brittle point-to-point connections. Link2Leap designs integrations around how the process works in practice, its data and its responsibilities.
When system integration becomes relevant
When the process crosses system boundaries
Integration comes into view when individual applications do their job, but the handovers between them slow the process down, make it fragile or leave responsibilities unclear.
- 01
Data is entered manually, exported or reconciled between systems.
- 02
A process crosses business, logistics, customer or specialist applications.
- 03
Existing point-to-point connections are fragile, difficult to understand or hard to change.
- 04
One system holds the trigger or data while another must perform the next action.
- 05
A new application must fit the existing landscape without duplicating logic or data ownership.
Not always the right route
Not every process problem needs a new integration
We start with the process and the responsibilities of existing systems. Sometimes the better answer sits within one system or a different boundary, without another API.
The right route may combine approaches, provided data ownership and process responsibility remain clear.
- 01
Improve the process within one system
Solve the issue at source when one existing system can carry the process well.
- 02
Use a standard integration
Use an available standard or native connector when it fits the functional and technical need well enough.
- 03
Build a targeted integration
Connect specific data and actions when a bounded handover is the missing link.
- 04
Introduce an orchestration or service layer
Coordinate multiple steps centrally when no single application owns the whole process.
- 05
Redesign boundaries or ownership
Reconsider system responsibilities when the structure of the landscape is itself the problem.
What we build
Integrations designed around a clear process responsibility
What we build depends on what must happen reliably between systems, when it must happen and who stays responsible when something deviates.
Data flows & synchronisation
Define which system owns which data, when information moves and how consistency is maintained.
Process orchestration
Coordinate multi-step workflows where no single application owns the entire process.
Integration architecture
Define boundaries, interfaces and responsibilities so connections remain understandable and maintainable.
How we approach integration
From process flow to controlled data and actions
We first clarify which data and actions must move between systems, then design the technical connection together with exception handling, recovery and handover.
- 01
Understand process & systems
We map the steps, handovers, applications involved and current failure points.
- 02
Clarify ownership & boundaries
We identify source systems, data ownership and where each responsibility belongs.
- 03
Design interface, event & flow
We choose an appropriate contract, event or data flow for each handover.
- 04
Build & validate
We implement the integration and test its behaviour using representative process paths and exceptions.
- 05
Design errors, monitoring & recovery
We make failures visible and define retries, recovery paths and accountable follow-up.
- 06
Document, transfer & evolve
We record decisions and dependencies so maintenance and change do not rely on implicit knowledge.
Technical depth
What must work beneath a reliable integration
A connection that works is not enough. Contracts, data meaning and exception behaviour determine whether the process remains manageable as systems change.
- APIs & contracts
- Clear agreements about data, actions, expectations and failure behaviour between applications.
- Data modelling & mapping
- Translate different data models without losing meaning or ownership.
- Events & asynchronous flows
- Where relevant, decouple events and processing without making sequence and status unclear.
- Identity & permissions
- At application-integration level, define which connection may use which data and actions.
- Error handling & retries
- Handle expected and unexpected failures without silent duplication or loss.
- Observability & logging
- Make process steps and handovers traceable so exceptions can be investigated.
- Testability & versioning
- Change interfaces in a controlled way and test important integration behaviour reproducibly.
What good integration can change
A process no longer dependent on isolated handovers
These are design goals, not guaranteed outcomes. What is achievable depends on the landscape, source-data quality and responsibilities in the process.
More connections are not the goal. What matters is a process that runs reliably and stays understandable.
- Less duplicate entry
- Information does not need to be recorded manually in multiple places.
- Fewer manual handovers
- Next steps can be initiated in a controlled way from an event or status.
- Clearer data ownership
- It becomes explicit which system is the source and where changes belong.
- More reliable process execution
- Failures, exceptions and recovery become part of the design rather than improvised responses.
- Lower coupling between applications
- Applications need less knowledge of each other’s internal workings.
- Changes easier to reason about
- Contracts and boundaries make the impact of adjustments more understandable.
Within Link2Leap
System Integration sits within Software Engineering
When integration reveals a deeper issue in existing software, architecture, modernisation or decision logic, Link2Leap can connect those disciplines around the same process. System Integration focuses on how existing systems work together. A new application is not the default answer.
Explore Software EngineeringWhere we are less likely to fit
Not every handover calls for integration engineering
Link2Leap is usually not the best fit when:
- A standard or native connector meets the need adequately with limited risk.
- The task is only moving files from A to B without meaningful process or engineering complexity.
- The organisation mainly wants a middleware or platform reseller.
- Unclear process ownership is the underlying problem and there is no willingness to resolve it first.
A process that breaks between systems?
Tell us which systems, data and handovers are involved and where the process fails. We can determine whether integration, orchestration or a different system boundary is the right route.
