    API Gateway:Domain Name Management

    Last Updated:Jun 23, 2026

    Manage domain names, change protocols and certificates, and configure HTTPS cipher suites in Cloud-native API Gateway.

    Create a domain name

    Note

    If you want to associate independent domain names with Cloud-native API Gateway instances in a region in the Chinese mainland, you must apply for ICP filings in the Alibaba Cloud ICP Filing system or add Alibaba Cloud as a service provider to the ICP filing information of the domain names. If you want to associate independent domain names with Cloud-native API Gateway instances in a region outside the Chinese mainland, ICP filings are not required.

    Cloud-native API Gateway provides multi-domain management for protocols, certificates, and route configurations. Complete ICP filing for your domain names before you proceed. For more information, see Create a domain name.

    Delete a domain name

    For more information, see Delete a domain name.

    Change the protocol and certificate of a domain name

    You typically need to change the protocol or certificate of a domain name in the following scenarios:

    • The SSL certificate is expired. In this case, a new certificate is required to encrypt data being transmitted.

    • The domain name owner is changed.

    • The protocol of the website is changed from HTTP to HTTPS.

    For more information, see Change domain protocol and certificate.

    Configure an HTTPS cipher suite

    Important

    The version of your Cloud-native API Gateway instance must be 2.0.0 or later.

    An HTTPS cipher suite is a set of encryption algorithms and protocols used to establish secure communication between a server and a client. Configuring a cipher suite for your gateway instance helps ensure data security, compatibility, performance optimization, and regulatory compliance.
