Partner CAD import

Partner integrations such as Adam or Onshape can POST feature-tree payloads to import structured CAD context into Rowe without re-uploading geometry. Use a paid API key for /api/v1/cad/import-feature-tree, or a signed webhook for /api/v1/cad/partner-webhook.

POST /api/v1/cad/import-feature-tree

Partner systems send structured feature-tree JSON with a paid API key. Four Echelon proxies to the hosted Rowe runtime when available and falls back to local normalization otherwise.

Terminal

$ curl https://fourechelon.com/api/v1/cad/import-feature-tree \
    -H "Authorization: Bearer $FOUR_ECHELON_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
$     "partner": "adam",
$     "document_id": "doc_123",
$     "feature_tree": []
$   }'

Signed webhooks

For Adam-style push delivery, use partner CAD webhooks with FOUR_ECHELON_PARTNER_WEBHOOK_SECRET.
