Systems Integration & API Development
Where does information stop moving inside your business?
SEVN7 Intelligence connects software, data and workflows through secure APIs, integrations and proprietary technology layers.
We help organisations reduce duplication, remove fragile workarounds and make the platforms they already pay for more valuable together.
Buying software does not automatically create a connected business.
Sales, finance, operations, service, projects, marketing and ecommerce may each use specialist platforms that perform their own role well.
The difficulty begins between them.
Employees export files, copy records, update several systems and remember what should happen after each handover. Data becomes delayed, duplicated or inconsistent. Customers repeat information the organisation already holds.
Integration creates a controlled route for information and actions to move.
What problems can integration solve?
Duplicate data entry
Define which system owns each record and move approved updates to the platforms that need them.
Broken handovers
Allow a completed stage in sales, finance, operations or delivery to trigger the correct next workflow.
Manual reporting
Connect source systems to a reliable reporting or intelligence layer without creating an uncontrolled second version of the data.
Fragmented customer experience
Bring relevant account, project, order, support, document and reporting information into one secure customer environment.
Unofficial workarounds
Replace spreadsheets, copied notes and manual reminders that have become essential but remain poorly governed.
AI without business context
Give approved AI capabilities access to the information and tools required for a defined role – without unrestricted access to the organisation.
Should you replace the current software?
We favour interoperability over unnecessary replacement. The integration design should preserve the systems that remain valuable while creating a controlled route for data and actions to move between them.
Often, the stronger answer is connection rather than replacement.
Before recommending a new platform, we consider what the current system does well, where friction actually occurs, whether reliable APIs exist, the cost of migration and whether a proprietary layer could solve the gap.
What can we connect?
Integration architecture
The right pattern depends on the systems, volume, timing and consequence of failure.
APIs
REST, GraphQL or provider-specific APIs can support direct, governed exchange where reliable interfaces exist.
Webhooks and events
Event-driven patterns can move work when something changes rather than relying on constant polling or manual export.
Scheduled or batch synchronisation
Where real-time data is unnecessary, controlled batch movement can be simpler, cheaper and easier to operate.
Middleware and integration layers
A dedicated orchestration layer can help when several systems need shared mapping, validation, routing or monitoring.
Legacy interfaces
Where modern APIs are unavailable, we assess supported exports, database access, file interfaces or carefully controlled alternatives before committing to a fragile workaround.
- CRM and sales platforms
- finance and billing systems
- project and workflow tools
- ecommerce platforms
- analytics and marketing systems
- document and knowledge platforms
- customer-support software
- internal databases
- proprietary products
- AI models and agents
- third-party data providers
Technical access and provider terms determine what is possible. We verify those constraints before committing to an approach.
Every important record needs a source of truth.
Data contracts and schema
Important integrations should define the fields, formats, validation rules, ownership and version expectations on both sides. This reduces silent breakage when a provider or internal system changes.
Identity and access
OAuth, OIDC, service accounts, API keys, scoped credentials and role-based controls can be used according to the provider and risk. Credentials should be protected and access should be revocable without redesigning the complete workflow.
We define:
- where the record originates
- which platform remains authoritative
- which fields other systems may update
- how often information synchronises
- how duplicates and conflicts are handled
- what happens when the source is unavailable
- how changes and failures are logged
- who owns data quality
What happens when an integration fails?
Depending on the process, we may use idempotency or duplicate protection, retries, dead-letter or failed-record queues, reconciliation, timeouts, circuit-breaker patterns, reauthorisation and manual fallback. The precise controls depend on the technology and business consequence.
Failure should be visible and recoverable.
Depending on the process, we design error detection, retry logic, failed-record queues, duplicate prevention, reconciliation, reauthorisation, manual fallback and clear operational ownership.
A business-critical connection should never stop silently.
Secure by design
Security should also account for secrets management, transport protection, input validation, logging, provider permissions and the blast radius of a compromised integration. Where sensitive systems are involved, least privilege is a design requirement rather than an afterthought.
Each integration should have the minimum access required, with scoped authentication, encrypted credentials, protected APIs, logging and immediate access withdrawal.
Integrations make agents operational.
With governed access to approved systems, an agent can check account status, retrieve knowledge, create a draft task, request missing information or trigger an approval.
Integration assurance and observability
We can test mapping, validation, permissions, rate limits, error paths, retries and recovery before release, then monitor connector health, latency, failures and changes in provider behaviour after go-live.
Total cost and vendor dependency
The design should account for API pricing, provider limits, contractual dependencies, maintenance effort and the cost of changing or replacing a supplier later.
Systems & Integration Review
A focused review can map systems of record, key interfaces, duplicated data, manual handovers, authentication, failure points and the integration sequence that would create the strongest operating value.
Make existing technology investments work harder.
A strong integration layer can reduce manual work, improve data accuracy, create a more consistent customer experience, support better reporting and prepare the business for AI-enabled workflows.
