http://openhaldex.local(or controller IP) - Response format:
JSON
API Endpoint
Set Mode
Set runtime mode with alias parsing and capture safety guard.
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/modeand 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.
