Parameter	Type	Description
publish_id	String	API publication record ID.
api_id	String	API ID.
group_name	String	Name of the API group to which the API belongs.
binding_time	String	Binding time.
env_id	String	ID of the environment in which the API has been published.
env_name	String	Name of the environment in which the API has been published.

api_name	String	API name.
id	String	Binding record ID.
api_remark	String	API description.
sign_id	String	Signature key ID.
sign_name	String	Signature key name. It can contain 3 to 64 characters, starting with a letter. Only letters, digits, and underscores (_) are allowed.
sign_key	String	Signature key. hmac: The value contains 8 to 32 characters, including letters, digits, underscores (_), and hyphens (-). It must start with a letter or digit. If not specified, a key is automatically generated. basic: The value contains 4 to 32 characters, including letters, digits, underscores (_), and hyphens (-). It must start with a letter. If not specified, a key is automatically generated. public_key: The value contains 8 to 512 characters, including letters, digits, and special characters (_-+/=). It must start with a letter, digit, plus sign (+), or slash (/). If not specified, a key is automatically generated. aes: The value contains 16 characters if the aes-128-cfb algorithm is used, or 32 characters if the aes-256-cfb algorithm is used. Letters, digits, and special characters (_-!@#$%+/=) are allowed. It must start with a letter, digit, plus sign (+), or slash (/). If not specified, a key is automatically generated.
sign_secret	String	Signature secret. hmac: The value contains 16 to 64 characters. Letters, digits, and special characters (_-!@#$%) are allowed. It must start with a letter or digit. If not specified, a value is automatically generated. basic: The value contains 8 to 64 characters. Letters, digits, and special characters (_-!@#$%) are allowed. It must start with a letter or digit. If not specified, a value is automatically generated. public_key: The value contains 15 to 2048 characters, including letters, digits, and special characters (_-!@#$%+/=). It must start with a letter, digit, plus sign (+), or slash (/). If not specified, a value is automatically generated. aes: The value contains 16 characters, including letters, digits, and special characters (_-!@#$%+/=). It must start with a letter, digit, plus sign (+), or slash (/). If not specified, a value is automatically generated.
sign_type	String	Signature key type. hmac basic public_key aes To use a basic signature key, ensure that your gateway version supports it. If your gateway does not support this type of signature key, contact technical support to upgrade your gateway. To use a public_key signature key, ensure that the public_key feature has been configured for your gateway. For details, see "Appendix" > "Supported Features". If your gateway does not support this feature, contact technical support to enable it. To use an AES signature key, ensure that your gateway version supports it. If your gateway does not support this type of signature key, contact technical support to upgrade your gateway. Enumeration values: hmac basic public_key aes
