Query Parameters
`include` string[] Possible values: [`custom`, `type`, `status`] List of additional/complex metadata to include in the response. Omit this query parameter if you don't want to retrieve additional metadata.
`auth` string String which is either the auth key (PAM v2) or a valid token (Access Manager) used to authorize the operation if access control is enabled. Authorization token with permissions to perform the request.
`signature` string Signature used to verify that the request was signed with the secret key associated with the subscribe key. If Access Manager is enabled, either a valid authorization token or a signature are required. Check Access Manager documentation for details on how to compute the signature.
`timestamp` integer Unix epoch timestamp used as a nonce for signature computation. Must have no more than ± 60 seconds offset from NTP. Required if `signature` parameter is supplied.
