Authorizations

​
X-Hook0-Signature
string
header
required

HMAC-SHA256 signature of the raw request body, computed using your webhook secret. Webhook receivers should always verify this header before processing the event. The header value is hex-encoded and prefixed by the algorithm and timestamp, e.g. t=1700000000,v1=abc123... (refer to the Webhook Security docs for the exact verification algorithm).

This scheme applies to webhook delivery (outbound POSTs from CDP to your endpoint), not to inbound CDP API requests.
