Authorization
string
header
required

Recommended authentication for new integrations. Generate a short-lived JWT from your API Secret ID and API Secret Key, then pass the signed JWT as a bearer token in the Authorization header.

Sign the JWT with HMAC-SHA256 using this signing secret:

Send the signed JWT as a bearer token:

Tokens expire 5 minutes after the iat timestamp. Generate a new JWT per request, or cache it briefly for less than 5 minutes. Generate JWTs only from trusted server-side code; do not expose the API Secret Key in browser, mobile, or other client-side code.
