API 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 the place where projects most often go wrong. ZebIQ designs, builds, and integrates APIs with the rigour of an infrastructure team: clear contracts, versioning strategies, authentication done right, and documentation that other developers actually enjoy using.
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.
What's included
API Design & Documentation
OpenAPI-specified REST and GraphQL APIs with versioning strategy, sandbox environments, and developer-friendly docs.
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.
How it works
A clear, numbered path from kickoff to live operation — so you always know what happens next.
Contract-First Design
We define the API specification and integration contracts up front, reviewed with all consuming teams before implementation.
Build with Tests
Implementation alongside automated contract and integration tests, validated against sandbox environments of every third party.
Staged Rollout
Deployment behind feature flags with canary traffic, monitored before full cutover from legacy paths.
Operate & Document
Runbooks, dashboards, and developer documentation handed over, with optional ongoing API operations support.
Where it shines
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.

Frequently asked
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.
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.
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.
