Standards and Specifications

API development according to international standards: REST, OpenAPI/Swagger, JSON\: API, gRPC, SOAP, WSDL - for compatibility, scalability and simplified integration.
Expert Stanislav Anisimov

High-quality API integration is impossible without complying with industry standards and specifications. We build our APIs on international protocols and architectural approaches, providing predictable behavior, ease of implementation, and scalability.

Both classic protocols (SOAP/WSDL) and modern solutions (REST, GraphQL, gRPC) with complete documentation and automated SDK generation are supported.

What standards are used

Standard/Approach Purpose and scope
REST (RFC 7231) Architectural style for building HTTP interfaces
OpenAPI / Swagger Specification for REST API Description and Documentation Generation/SDK
GraphQL (Facebook) Flexible, precisely structured data requests with a single point of entry
gRPC + Protobuf Fast binary protocol for microservices and high-load systems
SOAP + WSDL Standardized XML interface for integration with banking/government. systems
JSON\:API Unified JSON communication style

What is implemented

APIs are described according to the OpenAPI 3 standard. 0 +, with Swagger UI generation

Support for client SDKs for popular languages ​ ​ (PHP, Python, JS, Java, Go)

Input/Output Typing and Validation

Custom Query, Filter, Pagination, and Sort Options

Authorization specifications: API key, OAuth2, JWT, HMAC, etc.

Developer and Partner Benefits

Transparent structure and complete documentation

Quick generation of SDKs and Postman collections

Easy connection without manual interface analysis

Easy stack-independent scalability

Flexibility - REST and GraphQL can work simultaneously, for different tasks

Where especially important

Integration with external platforms, providers, payment systems

Development of frontend and mobile clients

API-first or backend-for-frontend commands

Projects with industry compliance requirements (PCI DSS, ISO 27001, etc.)


Support for standards and specifications is the key to fast, secure and predictable integration. We build APIs that are easy to connect, easy to document and safe to scale.
