    API Gateway:Change domain protocol and certificate

    Last Updated:Jun 02, 2026

    Change the protocol or certificate of a domain name when the SSL certificate expires, the domain owner changes, or you want to upgrade from HTTP to HTTPS.

    Procedure

    1. Log on to the API Gateway console.

    2. In the left-side navigation pane, click Domain Name. In the top navigation bar, select a region.

    3. On the Domain Name page, click the target domain name.

    4. On the domain name details page, click Edit to change the protocol or certificate.

      • Change the protocol: Select a protocol from the drop-down list next to Domain Name, and then click OK.

        Note

        Cloud-native API Gateway supports HTTP and HTTPS. HTTPS requires an SSL certificate. Supported ports:

        • HTTP: port 80.

        • HTTPS: port 443.

      • Change the certificate: Select a certificate from the Certificate drop-down list, and then click OK.
