Native REST API

The REST API that TIA Portal deserved.

TIA Portal doesn't have a native REST API. T-IA Connect fills this gap by exposing all features through standard HTTP endpoints. Integrate TIA Portal into any technology stack.

Why REST?

HTTP is the universal standard

REST is the world's most used API protocol. Every language, framework and tool supports it natively.

Universal

Python, JavaScript, Java, Go, Rust... Any language can make HTTP calls. No proprietary SDK.

Stateless

Each request is independent. Ideal for scaling, load balancing and microservices architectures.

Cacheable

Responses can be cached. Optimal performance for frequent reads.

Standard

HTTP verbs (GET, POST, PUT, DELETE), status codes, headers... Everything is standardized and documented.
