Integration & API Management
Connect your systems. Give your teams more time.
Duplicate data, fragile point-to-point connections and unclear error cases slow down digital processes. We connect applications via traceable interfaces and create order in the API lifecycle. This makes data flows controllable, partners easier to integrate and changes to individual systems easier to control.
Your options
Services that move your project forward
Map existing integrations
We record data sources, target systems, responsible parties and critical dependencies. Duplicate interfaces and manual handovers become visible.
You will receive a prioritized overview of the most sensible improvements.
Design APIs and contracts
We document data formats, business meaning and error responses. Versioning and changes are planned around the systems that consume each API.
Interfaces can be used and further developed more consistently.
Implement data flows
We connect synchronous APIs, messages, and scheduled transfers according to the respective process needs. Validation and mapping are part of the implementation.
Information arrives at the right destination in a defined form.
Access control and API gateways
Authentication, authorizations, limits and approvals are coordinated. A gateway is used where central control creates a concrete benefit.
Published functions are given comprehensible access rules.
Detect and resolve errors
We plan retries, duplicate handling, undeliverable messages and conflicts between business rules. Correlation identifiers and monitoring make individual operations traceable.
Errors don't disappear unnoticed between your systems.
Manage the API lifecycle
Each interface has documentation, an owner, tests and a plan for retiring old versions. Teams have a clear process for adding integrations.
New connections do not have to start from scratch every time.
Where to start
Integration & API Management Use cases
Three example situations show how we can help.
Connecting ERP and CRM
Customer data and order status need to remain consistent. We identify the authoritative system for each data type and agree conflict rules before automating transfers.
Connect partners faster
A business partner needs access to selected functions. Documented APIs, appropriate authorizations and an agreed test path facilitate integration.
Stabilizing fragile interfaces
Scheduled transfers fail repeatedly. We examine failure patterns and establish traceable retry and correction procedures.
From requirements to results
A clear process with agreed milestones
Map the data flow
We record sources, destinations, business meaning and existing errors together.
Agree API contracts
We agree communication patterns, data ownership, security and operational responsibilities.
Test the integration
We implement a defined workflow and test it, including failures and retries.
Expand in an orderly manner
Documentation and monitoring accompany the handover. Further data flows follow in order of priority.
Your benefit
What you receive
- Integration overview with responsibilities and dependencies.
- Documented API contracts and data mappings.
- Implemented interfaces with error and retry handling.
- Tests, monitoring requirements and handover documents.

Platform experience for your project
We use these selected tools in SYNEDAT PLATFORM or its delivery processes. We adapt suitable practices to your project and align their integration with your existing systems.
From source code to verified artifacts
Azure DevOps · GitLab · Jenkins · Harbor · Nexus
Version control, build processes and artifact repositories make software versions traceable. Our platform approach connects these activities with defined checks and approvals. For your project, we select tools that fit your teams and existing processes.
A clear delivery process and traceable software versions.
Developer access and shared knowledge
Backstage · code-server · Structurizr · Swagger UI
A service catalog, suitable development environments, architecture views and API documentation help teams find their way and work together. The focus is on useful workflows and maintained information. An additional portal alone does not remove an organizational bottleneck.
Less time searching and an easier start for development teams.
Quality and the software supply chain
SonarQube · Trivy · Dependency-Track · DefectDojo · Renovate · Syft · Cosign
Code quality, vulnerabilities, dependencies and artifact provenance require different checks. Findings need to be linked to the product and delivered version, with a defined process for resolving them. Automated checks complement reviews and informed decisions.
Security and quality information that teams can act on.
Questions before you get started
Do we need a new integration platform for this?
Not necessarily. We evaluate existing features and the expected scope of integration. A new platform must justify its additional licensing, operational, and learning effort with concrete benefits.
REST API or Events: Which Fits Better?
That depends on the process. Direct inquiries are suitable for a timely response; events can decouple systems in time. Both patterns are often combined. Data consistency and error handling also determine the design.
How do we avoid API change failures?
Contracts, compatibility tests and coordinated versioning rules make effects visible at an early stage. Transition periods and the replacement of old versions are planned with the affected consumers.
What happens if a connected system fails?
For each data flow, we define which operations can wait and which need an immediate response. Timeouts, bounded retries, buffering and manual correction procedures are implemented and tested according to the business requirements.
How do you prevent duplicate orders or bookings?
Appropriate transaction identifiers and idempotent processing ensure that repeated messages do not inadvertently trigger the same business transaction multiple times. The concrete implementation depends on the capabilities of the systems involved and is tested with repeat cases.
Can older systems be integrated without a modern API?
We examine supported exchange options such as files, data exports or existing connectors. Stability, manufacturer support and operational costs are taken into account. Not every technical access option is a suitable permanent integration path.
How is sensitive data protected in interfaces?
We limit transmitted data to the required scope and plan authentication, authorizations, and transport encryption. Logs and error messages should not reveal unnecessary confidential content. Retention and access are coordinated in the project.
What do our partners get for API usage?
The agreed scope can include machine-readable interface descriptions, examples, test accesses and notes on error handling. Responsibilities and changes are documented so that integration does not depend on informal individual knowledge.
