External orders & POS

Ingest a signed external-order cancellation revision

POST/external-order-ingress/{sourceId}/orders/{externalOrderId}/cancel

Open native orders are canceled atomically. Submitted orders remain available for explicit operator resolution. Hallify HMAC profile external-orders uses HMAC-SHA256. Canonical input: RFC3339 timestamp + "." + key-sorted stable JSON. Send x-hallify-timestamp as rfc3339; timestamps outside ±300 seconds are stale. Send x-hallify-signature as lowercase hexadecimal; comparison is timing-safe. Secret handling: Use the issued base64url text as the UTF-8 signing secret. Accepted Content-Type: application/json. Malformed input: A malformed signature returns 401 Webhook signature is invalid. Stale input: A timestamp outside the 300-second window returns 401 Webhook timestamp is stale. Repeated delivery: Order revision and payload fingerprint semantics control duplicate and conflicting delivery.

Authentication

x-hallify-signature: <HALLIFY_SIGNATURE>

HMAC-SHA256 signature credential. Each operation documents its exact protocol through x-hallify-hmac metadata and the operation description.
