Businesses Using Multiple Tools
Connect CRMs, ERPs, payment gateways, and internal apps with two-way sync β so your data lives in one consistent state, not four.
Who we build for
Who We Build APIs & Integrations For
Most products break at the seams between systems. We design APIs that hide complexity from the caller and integrations that survive partner outages β so your data flows where it should and your team stops copying-pasting between tools.
Teams Needing Real-Time Data Flow
Webhook-driven, event-aware integrations that move data the moment it changes β instead of nightly batches that mask real problems.
Companies Modernising Legacy Systems
Wrap old systems with clean APIs so new products can move quickly β without ripping out what already works.
Platforms Exposing Public APIs
REST or GraphQL APIs designed for third-party developers β with auth, rate limiting, versioning, and docs you would not be embarrassed to share.
Why Chayaniq for APIs
API Development & Integration Benefits
Most products break at the seams between systems. Here is how we engineer APIs and integrations that hide complexity from callers and survive the messy reality of partner outages.
REST & GraphQL API Design
Clean, consistent API contracts with versioning, pagination, and error semantics β designed so consumers (your team or partners) integrate fast.
Third-Party Platform Integrations
CRMs, ERPs, payment gateways, and SaaS tools β connected with two-way sync and conflict-aware data handling.
Webhook & Event-Driven Architectures
Webhook receivers with signature verification, retries, and idempotency β so events do not disappear quietly and data stays consistent.
Data Pipeline & ETL Development
Extract, transform, and load pipelines that move data reliably between systems β with backfills, reconciliation, and clear observability.
Legacy System Modernisation & API Wrapping
Wrap old systems with clean APIs so new products move quickly β without ripping out what already works.
OAuth 2.0, SSO & Secure Authentication
OAuth flows, SSO integrations (Azure AD, Cognito), and token management implemented with the security details done right.
Industries we serve
API & Integration Work Across Industries
Every industry has its own integration stack β EHRs in healthcare, ERPs in manufacturing, MLS in real-estate. We have stitched them together across the verticals below.
Remote patient monitoring
- Real-time collection of wearables data
- Enhanced doctor-patient communication
- Comprehensive view of patient health data
- Data-driven report generation
- Seamless integration with existing systems
- Improved patient outcomes
Electronic medical records (EMR)
- Interoperability of medical data across departments
- HIPAA / GDPR compliant solutions
- Improved patient care
- Quick access to patient records, vitals, and lab results
- Enhanced security and privacy of patient health data
Document management
- Compliant documentation workflow
- Streamlined management of health information
- Integrations with existing systems for a 360Β° data view
- Secure file sharing and access management
Insurance verification
- Automated medical insurance eligibility
- Proactive identification of coverage issues
- API-ready and HIPAA-compliant
How we work
Our Process for APIs & Integrations
Integrations age fast when they are not designed defensively. Our process focuses on contracts, observability, and reversibility β so every integration we ship survives partner changes.
Discovery
We map source systems, data flows, and SLAs β including the corner cases your team has been working around for years.
Contract Design
REST or GraphQL contracts with versioning, error semantics, and pagination β published so consumers can integrate without guesswork.
Build
Idempotent, retryable, and observable integrations β with auth, secrets, and signature verification done right.
Testing
Contract tests, fault-injection, and replay-based tests β so partner outages are something you handle, not something that wakes you up.
Deployment
Phased rollouts with structured logs and traces β automations go live in a state your on-call team can actually support.
Monitoring
SLA dashboards, anomaly detection, and runbooks linked from alerts β integrations stay healthy and incidents close fast.
How we ship APIs & integrations
Most products break at the seams between systems. We engineer APIs and integrations that hide complexity from the caller and survive partner outages.
Clean, consistent API contracts with versioning, pagination, and error semantics β designed so consumers integrate fast.
- Schema-first design with OpenAPI or GraphQL SDL
- Auth, rate limiting, and tenant isolation handled at the edge
- Generated SDKs and docs you would not be embarrassed to share
