ExploreAPI Development & Integration
Production-grade REST and GraphQL APIs, third-party integrations, and middleware that make your systems talk to each other reliably.
APIs are the connective tissue of modern business — and where projects most often go wrong. ZebIQ designs, builds, and integrates production-grade REST and GraphQL APIs with the rigour of an infrastructure team: clear contracts, versioning strategies, authentication done right, and documentation that other developers actually enjoy using.
APIs That Connect Your Systems Reliably
We work on both sides of the interface.
On the build side: REST and GraphQL APIs with OpenAPI specifications, rate limiting, OAuth2/JWT auth, and automated contract tests.
On the integration side: Connecting your platforms to payment gateways, government systems, logistics providers, CRMs, messaging platforms, and event-tech tools — with retry logic, circuit breakers, and monitoring, because third-party services fail and your system shouldn't fail with them.
For event clients, this often means the unglamorous work that makes a show run: badge printers talking to registration systems, access-control turnstiles validating against live ticket data, and sponsor lead-capture apps syncing to exhibitor CRMs in real time.
Core Capabilities
API Design & Documentation
OpenAPI-specified REST and GraphQL APIs with versioning strategy, sandbox environments, and developer-friendly documentation.
Authentication & Security
OAuth2, JWT, API keys, and scoped permissions implemented to current best practice, with rate limiting and abuse protection.
Resilient Third-Party Integrations
Retries with backoff, circuit breakers, idempotency, and dead-letter queues — so a partner outage degrades gracefully instead of cascading.
Middleware & Data Sync
Event-driven pipelines and transformation layers keeping CRMs, ERPs, and operational tools consistent in near real time.
Webhook Infrastructure
Signed, verified, replayable webhook systems for both consuming partner events and publishing your own.
Monitoring & SLAs
Latency, error-rate, and uptime dashboards with alerting, plus structured logs for fast incident diagnosis.
Contract-First, Tested, Staged, Documented
Our API Development Process
1. Contract-First Design We define the API specification and integration contracts up front, reviewed with all consuming teams before implementation.
2. Build with Tests Implementation alongside automated contract and integration tests, validated against sandbox environments of every third party.
3. Staged Rollout Deployment behind feature flags with canary traffic, monitored before full cutover from legacy paths.
4. Operate & Document Runbooks, dashboards, and developer documentation handed over, with optional ongoing API operations support.
Why API Architecture Matters

Common Use Cases
Event-Tech Stack Integration Registration, badging, access control, and lead-retrieval systems unified into one real-time data flow for large exhibitions.
Partner & Public APIs Documented external APIs that let partners, resellers, or developers build on your platform securely.
Legacy System Modernisation API layers wrapped around older ERP or database systems, letting modern apps consume legacy data safely.
The difference between a working integration and a fragile one is invisible to users — until it breaks at the worst moment. Good API design is invisible infrastructure that earns its keep through reliability, not visibility.
Frequently Asked Questions
REST or GraphQL — which do you recommend?
REST remains the right default for public and partner APIs due to simplicity and cacheability; GraphQL shines for complex internal frontends consuming many entities. We frequently use both in one system and will recommend based on your consumers, not fashion.
How do you handle third-party API changes and outages?
Defensively: adapter layers isolate each integration, contract tests catch breaking changes early, and retries, circuit breakers, and fallback paths ensure a partner outage degrades your system gracefully rather than taking it down.
Can you take over and fix an existing integration mess?
Yes — it is a common engagement. We start with an integration audit mapping every data flow and failure mode, stabilise the worst offenders with monitoring and retry logic, then refactor incrementally without halting your operations.
Let's Build Reliable APIs Together
Whether you need a new production API, resilient third-party integrations, or help untangling existing systems, ZebIQ brings infrastructure-grade discipline to API design and operations.
