Versioned HMAC-SHA256 signature authenticating server-to-server SDK requests (your backend calling Stash), as opposed to client-side SDK operations. Recommended over the deprecated X-Stash-Api-Key for the best security. Header format: v1;{appId};{unixMillisTimestamp};{base64Signature} (semicolon-delimited). {base64Signature} is the base64-encoded HMAC-SHA256 of the string {unixMillisTimestamp}.{requestBody} using your app ingress secret (the ingress secret is shown base64-encoded in Studio; base64-decode it to the raw bytes used as the HMAC key), where {requestBody} is the compact canonical request JSON for POST requests and empty for GET requests. The timestamp must be within 5 minutes of Stash server time. Your appId is your immutable app identifier, shown in Stash Studio under Project Settings > App details; your ingress secret is under Project Settings > API Secrets.
