SATIK DEVELOPER DOCS · V1 BETA

Signed updates. Straight to your system.

Receive batch completion and quota notices on a public HTTPS endpoint.

Connect an endpoint

In Webhooks, add a public HTTPS URL. Save the signing secret, shown once. Satik encrypts it at rest. Redirects, credentials in URLs, IP literals, and private-network destinations are blocked.

Verify the signature

Validate the signature against the exact raw request body before processing an event.

Webhook signature checks
Check	How to verify
Signature header`Satik-Signature`	Parse t=<unix>,v1=<hex> into timestamp and signature.
Expected signature`HMAC-SHA256`	Use the endpoint secret to sign timestamp + "." + the exact raw request body.
Signature comparison	Compare signatures in constant time.
Timestamp tolerance	Reject timestamps outside a five-minute window.
Duplicate event	Deduplicate by event ID before applying the event again.
