Your API key (configured in credentials)

HMAC-SHA256 signature (auto-generated) To test manually: HMAC-SHA256 of apiKey + timestamp (or apiKey + timestamp + userId when X-User-Id is required), keyed with your API secret. The HMAC Generator flow computes this for you.

Unix timestamp in seconds (auto-generated) Unix seconds, e.g. Math.floor(Date.now() / 1000). Must match the timestamp used in the X-Signature computation.

Unique request identifier (auto-generated) Any unique string per request, e.g. a UUID.
