REST is the universal integration protocol. ScadaHud ships both a REST client (poll any HTTP endpoint and turn the response into tags) and a REST server (expose your tags, history and alarms to ERP, MES and custom apps).
What is REST API?
REST is an architectural style on top of HTTP using GET, POST, PUT, DELETE methods and JSON or XML payloads. Any modern web service speaks REST: weather APIs, energy markets, ERP systems, cloud platforms, custom microcontroller endpoints. Authentication is typically Bearer token, API key, or Basic.
What ScadaHud's driver supports
- GET, POST, PUT, DELETE methods
- JSON-path tag extraction
- Bearer token, API key (header or query), Basic and OAuth 2.0 client credentials
- TLS verification with custom CA pinning
- Configurable polling interval and request timeout
- Outbound REST server: read tags, query history, list alarms via authenticated HTTPS
Common use cases
- Weather and grid pricing data acquisition
- ERP / MES integration (SAP, Odoo, Dynamics)
- Cloud platform integration (AWS, Azure, GCP)
- Custom microcontroller and edge devices speaking JSON
- Power / energy market signals from ENTSO-E, EPIAS, MISO
Generic, anything that speaks HTTP/JSON. Common targets: SAP, Odoo, Microsoft Dynamics, AWS Lambda, Azure Functions, Salesforce, ServiceNow, custom ESP32/Raspberry Pi gateways.
