Authorizations
Signed (HMAC) authentication. Required headers: x-access-id, x-request-id (UUID v4), x-timestamp (ISO 8601, must be within 5 minutes of server time), and authorization: the Base64 HMAC-SHA256 of the JSON string {"timeStamp":"","requestId":"","accessId":""} (keys in that order, no whitespace) using your access secret. The request body, method and path are not signed. The API key must be linked to an outlet.
Headers
