Integration specification
Systems, actors, events, fields, ownership, authentication, limits, dependencies, and acceptance cases.
Harmita services
API integration.
Connections your team can understand.
A reliable integration is more than a successful demo request. We define ownership, map the data, handle expected failures, and leave a testable record of how the connection works.
Scoped to your project
A defined outcome.
Reviewable work.
- Data and ownership mapped first
- Failures and retries designed explicitly
- Testing and handover included
Final deliverables, schedule, fees, and responsibilities are confirmed in a proposal.
Where it fits
Useful when the problem is clear.
These are common starting points, not a qualification checklist. Discovery confirms whether this service is a sensible fit.
- A website sending enquiries to an existing business system
- A product connecting an approved payment, messaging, or fulfilment provider
- A team replacing repeated spreadsheet imports or manual copying
- An application exposing a defined interface to an authorised system
Problems to solve
Start with the friction, not a package.
A useful brief names what is failing today and what a better operating state would look like.
- The same information is copied between systems by hand
- Data arrives without validation or clear ownership
- Failures are silent, duplicated, or difficult to replay
- An existing integration lacks documentation and tests
Possible deliverables
Concrete work you can review.
The proposal selects and adapts the deliverables needed for your objective. Items not named in the proposal are not implied.
Secure connection and mapping
Approved authentication, secret handling, field transformations, validation, and least-privilege access.
Reliability controls
Idempotency where relevant, timeouts, retries, webhook verification, meaningful logs, and partial-failure handling.
Test coverage
Happy path, invalid inputs, duplicate events, provider errors, and representative edge cases.
Documentation and handover
Configuration inventory, data flow, runbook, known limits, provider dependencies, and future ownership.
How the work moves
Decisions and inputs are visible.
Each stage names what Harmita does and what we need from your team, so dependencies do not disappear inside a timeline.
- 01
Map the workflow
Identify source, destination, event, data fields, volume, latency needs, and owners.
Needed from you: An owner for each system, API docs, test environments, and representative records.
- 02
Design failure-safe behaviour
Agree on authentication, validation, duplicates, retries, logs, alerts, and recovery.
Needed from you: Security requirements and decisions about what staff do when a connection fails.
- 03
Build and test
Implement the agreed paths and exercise them with representative and failure cases.
Needed from you: Test accounts, provider approvals, example payloads, and acceptance feedback.
- 04
Release and hand over
Coordinate configuration, monitor release, and document operation and ownership.
Needed from you: Credentials through an approved channel, release approval, and an operational contact.
Quote factors
What shapes scope and fees.
Fees are quoted after the scope is understood. The factors below usually change the effort, dependencies, and delivery plan.
- Number of systems, events, and data mappings
- API documentation and sandbox quality
- Authentication, compliance, and approvals
- Volume, latency, and reliability needs
- Migration, reconciliation, and monitoring needs
Boundaries and dependencies
Clear before work begins.
- Provider subscriptions, transaction charges, message fees, and usage charges are separate unless explicitly included.
- External availability, approval timelines, breaking changes, rate limits, and undocumented behaviour are provider dependencies.
- Production credentials should remain in approved secret storage and must not be sent through enquiry forms.
Questions, answered
A few things you might ask.
Questions about api integration, project scope, dependencies, and working with Harmita.
Can you integrate with an existing codebase?
Yes, after reviewing the platform, deployment process, documentation, code access, and test strategy. The review may identify prerequisites.
How long does an integration take?
It depends on systems, workflow count, authentication, documentation, approvals, test environments, and reliability requirements.
What happens when a provider is unavailable?
Behaviour is designed for the workflow. Options may include a safe error, queued retry, alert, manual recovery, or reconciliation; none is assumed.
Who owns the third-party accounts?
You should ordinarily own provider accounts, billing, and production credentials. Harmita receives only the access required for implementation.
