API Endpoint

Write Active MAP Table

Replaces active map bins and lock table.

POSTMap and Curves/api/map

Reach It

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

Query Input

None

Body Input

JSON with speedBins[9], throttleBins[7], lockTable[7][9]. lock values clamped 0..100.

Response / Parse

Receive: JSON: {"ok":true}

Parse: Rejects wrong dimensions/rows.

Error Behavior

400 invalid json/map sizes; 200 success

Example Call

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

Endpoint-Specific Engineering Notes

This section is intentionally unique for POST /api/map. Focus area: full map replacement with validation of table dimensions and values. When integrating OpenHaldex at scale, this endpoint should be treated as a dedicated workflow step rather than a generic HTTP action.

Operational scenario: Send a validated matrix payload, then re-read map and status to confirm firmware accepted the exact structure.

Domain vocabulary: map-upload, matrix-shape, bin-count, cell-clamp, table-sanitize, write-apply, active-map, draft-commit, table-atomicity, postwrite-read.

Common Mistakes for This Endpoint

Mismatched axis lengths
Values outside expected lock range
No immediate post-write verification

Practical Validation Pattern

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