API Development & Integration
REST, GraphQL and gRPC APIs designed for the load you expect — plus integrations with the third-party systems you already run.
We design and build APIs that power modern businesses — from internal microservices to public developer platforms. Our APIs are documented with OpenAPI, versioned, secured with OAuth 2.0 or OIDC, and designed against the request volumes and latency targets agreed for your workload.
In short: SOCIA designs and builds REST, GraphQL and gRPC APIs, and integrates the third-party systems a business already runs — payment gateways, ERP and accounting packages, logistics aggregators, biometric devices and internal services — behind a single documented contract.

What we deliver
Comprehensive capabilities that ensure your project's success from start to finish.
API Design First
OpenAPI 3.0 specs designed before code, reviewed with stakeholders.
Security & Auth
OAuth 2.0, JWT, API keys, mTLS, rate limiting, and WAF protection.
Performance Targets
Latency and throughput targets agreed per workload, with caching, connection pooling and CDN delivery where they apply.
Versioning Strategy
Semantic versioning, backward compatibility and a written deprecation policy.
Developer Portal
Generated docs, SDKs, a sandbox environment and usage analytics.
Integration Work
Integrations with the systems you actually run — CRM, ERP, payments, messaging and internal services.
