Build with EUHub service
API and business integrations
CRM, ERP, payment, email, analytics, logistics, and internal database integrations.
Direct definition
API and business integration development connects websites and applications to the systems that run sales, operations, payments, logistics and reporting. It includes data contracts, authentication, validation, retries, observability and accountable ownership of every failure path.
What this service solves
An integration is reliable only when both success and failure are designed. We document the source of truth, data mapping, authentication, rate limits, idempotency requirements and recovery behavior before connecting production systems.
Modern REST, GraphQL and webhook interfaces are supported alongside legacy SOAP services where replacement is not practical. Adapter boundaries keep protocol-specific complexity away from the user interface and make future system changes less disruptive.
Logs, metrics and alerts are designed around business consequences, not just HTTP status. A failed lead, duplicate payment or delayed logistics update must be identifiable and recoverable by the team that owns the process.
What the scope includes
How delivery works
Every engagement follows the same evidence-led path from diagnostic through launch and measured improvement.
- 01
Diagnostic
We review your website, offer, users, technical stack, analytics, and bottlenecks.
- 02
Architecture
We define sitemap, content structure, integrations, data flows, and technology choices.
- 03
Design system
We create the visual language, components, UI patterns, and responsive structure.
- 04
Engineering
We build the frontend, backend/API integrations, CMS/content model, analytics, and deployment pipeline.
- 05
Launch and improve
We deploy, monitor, measure, iterate, and maintain.
Questions about this service
Can you integrate with legacy SOAP APIs?
Yes. We isolate SOAP envelopes, authentication and error mapping behind a modern adapter so the website or application does not depend directly on legacy protocol details.
How do you prevent duplicate actions?
Where the receiving system supports it, we use idempotency keys, stable event identifiers and replay-safe handlers, with logs that make duplicate or delayed delivery visible.
Who monitors an integration after launch?
Monitoring and ownership are agreed before launch. A maintenance arrangement can cover alerts, incident response, credentials, vendor changes and controlled retries.

We will identify the highest-value scope, integration risks and evidence required before you commit to a build.
