API engineering and integration
We build and connect application programming interfaces to support secure exchange of records, transactions and events between systems.
We build and connect application programming interfaces to support secure exchange of records, transactions and events between systems. The engagement begins by clarifying existing processes, relevant users, technical dependencies and the decisions that need to be made. The precise scope and acceptance criteria are agreed before delivery.

How API Development & Integration Works
Every engagement starts with a clear understanding of the existing environment, the people involved and the outcomes that matter. The delivery activities below show how this service moves from discovery into an actionable plan.

Ideal for organisations that:
- Product teams and businesses exposing or consuming APIs
The Challenges We Solve
- When api contract design is not properly planned, teams may face delays, inconsistent results or difficult handovers.
- When versioning and rate-limit planning is not properly planned, teams may face delays, inconsistent results or difficult handovers.
- When security testing is not properly planned, teams may face delays, inconsistent results or difficult handovers.
The Business Value
- API endpoints and specifications: the intended output, review responsibilities and acceptance criteria are documented in the agreed scope.
- Authentication and access controls: the intended output, review responsibilities and acceptance criteria are documented in the agreed scope.
- Webhook and event workflows: the intended output, review responsibilities and acceptance criteria are documented in the agreed scope.
- Logging and integration tests: the intended output, review responsibilities and acceptance criteria are documented in the agreed scope.

What to Expect
Before commissioning api development & integration, clarify what is included, what remains the client's responsibility, dependencies on existing software or suppliers, security and data access, the acceptance process, and any post-delivery support. Timeframes and costs should be confirmed only after discovery.
Typical deliverables
- API endpoints and specifications
- Authentication and access controls
- Webhook and event workflows
- Logging and integration tests
Frequently Asked Questions
1. How do you secure an API?
The design considers authentication, authorisation, input validation, logging and sensible access limits.
2. Do you provide API documentation?
Endpoint contracts, expected payloads, error handling and test guidance can form part of the deliverables.
3. What does api development & integration actually include?
We build and connect application programming interfaces to support secure exchange of records, transactions and events between systems. The detailed statement of work identifies inclusions, exclusions and the outputs to be reviewed.
4. What business problem does api development & integration address?
Reliable interfaces make it possible for software products to exchange information safely. Discovery determines which symptoms and underlying causes are within scope.
5. Who should consider api development & integration?
Product teams and businesses exposing or consuming APIs. The right engagement depends on business objectives and the condition of existing systems.
6. What will we receive after api contract design?
The expected outputs can include api endpoints and specifications. Their format, ownership and acceptance criteria should be agreed before work starts.
7. How do you approach versioning and rate-limit planning?
We first establish the existing environment and dependencies, then plan versioning and rate-limit planning with agreed checks and stakeholder review.
8. How will authentication and access controls be reviewed?
The parties should agree how to inspect and accept authentication and access controls, including any test evidence or documentation required.
9. How long does the engagement take?
Timing depends on scope, system access, decision-making, dependencies and the complexity of security testing. A realistic schedule follows discovery.
10. Can you work with our existing software and team?
Compatibility, access rights and team responsibilities are assessed first. Existing tools can be retained where they meet the requirements and support the proposed work.
