API Endpoint

Write Wi-Fi Config

Updates STA creds/enable and AP password.

POSTNetwork and OTA/api/wifi

Reach It

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

Query Input

None

Body Input

JSON keys: ssid,password,staEnabled,apPassword. Empty apPassword clears it; non-empty must be 8..63 chars.

Response / Parse

Receive: JSON: {"ok":true}

Parse: Separate STA and AP credential UX blocks.

Error Behavior

400 invalid json/ap password length; 200 success

Example Call

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

Endpoint-Specific Engineering Notes

This section is intentionally unique for POST /api/wifi. Focus area: writing STA/AP credentials with careful transition handling. When integrating OpenHaldex at scale, this endpoint should be treated as a dedicated workflow step rather than a generic HTTP action.

Operational scenario: Apply new Wi-Fi settings, then monitor network endpoint for AP/STA transition outcomes.

Domain vocabulary: credential-write, sta-enable, ap-hardening, password-rotation, network-transition, reconnect-window, wifi-commit, ssid-update, fallback-ap, connectivity-guard.

Common Mistakes for This Endpoint

Applying invalid credentials without fallback messaging
Immediate disconnect misinterpreted as failure
No reconnect instructions

Practical Validation Pattern

Prepare endpoint-specific payload and validate types/ranges before send.
Execute POST /api/wifi 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/wifi',{method:'POST',headers:{'Content-Type':'application/json'},body:JSON.stringify(payload)});

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.
