API design
Define interfaces and data contracts around a clear system boundary.

Service Overview
Disconnected systems can make a workflow harder to understand and operate. Integration work begins by mapping where information originates, how it changes, and which system owns each decision. We define data contracts, authentication, failure behavior, and operational visibility before connecting services. The resulting scope should consider provider limits, changes to upstream interfaces, and how the connection will be supported over time.
What We Offer
Third-party connections
Connect approved providers after reviewing their interfaces and access requirements.
Workflow automation
Map repeatable steps and identify where automation is appropriate.
Data mapping
Agree how fields, identifiers, and ownership translate between systems.
Failure handling
Plan validation, retries where appropriate, and actionable error reporting.
Integration documentation
Describe contracts and operational expectations for future maintenance.
Tech Stack
Technologies We Work With
Design connections using REST APIs, GraphQL, and OpenAPI, with authentication and data contracts matched to the systems involved. Provider permissions and supported interfaces are assessed before implementation. The final stack and supported setup are agreed for each project.

Why Choose Devoynx
A clear scope
Make requirements, assumptions, and responsibilities visible before implementation.
Maintainable decisions
Consider how the software will be understood, operated, and changed over time.
Thoughtful delivery
Build verification and handover into the agreed plan rather than leaving them until the end.
Frequently Asked Questions
Can you connect a system without an existing API?
The available interfaces, data-access permissions, and vendor constraints need assessment. A safe integration approach cannot be assumed before that review.
What happens when an external service fails?
Failure behavior should be designed explicitly. Depending on the workflow, this may include validation, bounded retries, recovery steps, and clear operational alerts.
Who supplies third-party accounts and credentials?
The required account ownership and access should be agreed during planning. Credentials should be delivered through an approved secure channel and kept out of client code.
