# Receive Inbound Webhook

> Inbound webhook receiver. No Bearer auth — caller authenticates via HMAC
signature header (x-causeloop-signature or x-hub-signature-256).

H-1: Buffers raw bytes, resolves the connector's workspace + inbound webhook,
decrypts its signing secret, computes HMAC-SHA256 over the raw body, and FAILS
CLOSED — a missing secret, a missing signature header, or a mismatch all 401.
