API Endpoint

Set Mode

Set runtime mode with alias parsing and capture safety guard.

POSTCore Control/api/mode

Reach It

Method: POST
Path: /api/mode
Base URL: http://openhaldex.local (or controller IP)
Response format: JSON

Query Input

None

Body Input

JSON: {"mode":"MAP"}; aliases accepted.

Response / Parse

Receive: JSON: {"ok":true,"mode":"MAP"}

Parse: Case-insensitive aliases. Non-STOCK blocked in capture mode.

Error Behavior

400 invalid json/mode; 409 capture active; 200 success

Example Call

curl -s -X POST "http://openhaldex.local/api/mode" -H "Content-Type: application/json" -d '{...}'

Endpoint-Specific Engineering Notes

This section is intentionally unique for POST /api/mode. Focus area: deterministic mode switching with immediate user feedback. When integrating OpenHaldex at scale, this endpoint should be treated as a dedicated workflow step rather than a generic HTTP action.

Operational scenario: Submit one explicit mode intent, then refresh status and confirm the active mode id, UI highlight, and control gate state.

Domain vocabulary: mode-alias, state-transition, override, lock-profile, driver-intent, debounce, toggle-latency, mode-guard, fallback-mode, confirmation-banner.

Common Mistakes for This Endpoint

UI toggle reflects desired state before firmware confirms
Rapid multi-click mode changes causing user confusion
Not handling invalid mode values

Practical Validation Pattern

Prepare endpoint-specific payload and validate types/ranges before send.
Execute POST /api/mode and capture status code + raw response.
Parse response and apply only validated fields to UI state.
Run a follow-up read (usually /api/status) to verify runtime convergence.
Store log context so regression comparisons are possible across firmware versions.

Reference Snippet

await fetch('/api/mode',{method:'POST',headers:{'Content-Type':'application/json'},body:JSON.stringify({mode:'map'})});

Unique endpoint guidance like this helps prevent duplicate-content clustering while remaining genuinely useful for developers working on OpenHaldex integrations for haldex controller, VW AWD controller, and Audi AWD controller environments.
